Tasha is planning an expansion of a square flower garden in a city park. If each side of the original garden is increased by 10 m, the new total area of the garden will be 169 m2. Find the length of each side of the original garden
Answer:
6m
Step-by-step explanation:
To find the original length you must take away the add-ons. To do so we know that they added 7 and A= l*l (or l squared). They added the 7 to the length so multiply 7*7 (49) subtract your answer from 169 (120) and that's your new area. To find the original length divide by 4 (I believe) and get 30m2

= 4 1/20
= 4.05
Step-by-step explanation:
81/20 is the smallest it gets as a fraction I believe
and A. should be 5/4 if i'm not mistaken
Answer:
a) 1 1/4 or b) 4 1/20
Step-by-step explanation:
a) This one is the easier of the two. 7/8+3/8= 10/8 ---» 1 2/8 and 2/8 is 1/4. So 1 1/4.
b) This one is a bit more tricky. You need to find a common denominator between the two, in this case we can use 20.
9/5 ---» 36/20 and 9/4 ----» 45/20.
Do some adding and you get 81/20 ---» 4 1/20.

Consider the line 7x+5y=−2.
What is the slope of a line perpendicular to this line?
What is the slope of a line parallel to this line?
Answer: slope of a line perpendicular is [tex]\frac{5}{7}[/tex]; slope of a line parallel to this line is [tex]-\frac{7}{5}[/tex].
Step-by-step explanation:
Rewrite the line in y = mx + b form, where m is slope and b is y-intercept.
7x + 5y = -2
5y = -7x -2
y = [tex]-\frac{7}{5}[/tex]x - [tex]\frac{2}{5}[/tex]
The product of two slope of perpendicular line is -1.
Let x be the other line that perpendicular line with the line 7x + 5y = -2.
（[tex]-\frac{7}{5}[/tex])x = -1
x = [tex]\frac{5}{7}[/tex]
The slope of a line parallel to this line is the same, which is [tex]-\frac{7}{5}[/tex].
If an exponential model has a 9% decay rate,
what multiplier would be used in the function
model?
0.9 1.09
1.9 0.91
=====================================================
Explanation:
If you lose 9% of a substance, then you keep the remaining 91% because 100% - 9% = 91%. Or you can think of it as 91% + 9% = 100%
Then we convert 91% to decimal form to get 0.91
-----------
Or you can do the steps like this:
9% = 0.09
1 - 0.09 = 0.91

16. Marique is making a large table in the shape of a trapezoid. She needs
to calculate the area of the table. The longest side of the table is twice
as long as the table's width. Find the area of the table by decomposing
the trapezoid into familiar shapes. Show your work
Given that the length of the table is twice the width which is 1.25 m. and
the difference in the parallel side is 1 m., the area of the table is 2.5 m².
How can the area of the table be calculated?The possible table dimensions are;
Width of the table = 1.25 m
Width of the table = The height of the trapezoid
The difference in length between the parallel sides = 2 × 0.5 m = 1 m
Longest side of the table is a parallel side of the trapezoid
Given;
Length of the longest side of the table = 2 × The width
Which gives;
Length of the longest side of the table = 2 × 1.25 m = 2.5 m
Length of other parallel side = 2.5 m - 1 m = 1.5 m
[tex]Area \ of \ a \ trapezoid = \mathbf{\dfrac{Sum \ of \ length \ of \ parallel \ sides}{2} \times Height}[/tex]
Which gives;
[tex]\mathbf{Area \ of}\ the \ \mathbf{table} = \dfrac{2.5 + 1.5}{2} \times 1.25 = 2.5[/tex]
The area of the = 2.5 m²

https://brainly.com/question/4758162
— length of the longest side of the table = 2 × width which gives you 'length of the longest side of the table = 2 × 1.25 meters' which equals 2.5 meters. to find length of other parallel side use the equation 2.5 meters minus 1 meter, which is 1.5 meters. lastly to find the area, do [tex]\frac{sum of length of parallel sides}{2}[/tex] multiplied by the height, which afer you fill it out turns into [tex]\frac{2.5+1.5}{2} *1.25[/tex] , which equals 2.5 meters. so the area is 2.5 meters squared.

Each of 5 gift bags contains x pencils. Tyler adds 3 more pencils to each bag. Altogether, the gift bags contain 20 pencils.
Write an equation for the story. (use "X")
what is the reason for multiplication in the story?
Explanation:
Each of the five bags contain x pencils, where x is a placeholder for a positive whole number.
This means Tyler starts off with 5x pencils
He then adds 3 pencils per bag, so 3*5 = 15 extra pencils, to get the expression 5x+15. We're told the new grand total is 20 pencils.
Therefore, the equation for this story problem is 5x+15 = 20
The reason for the multiplication is because we have the same number of pencils per bag. So we're adding multiple groups together, or using multiplication to do a shortcut.
eg: instead of 5+5+5 = 15 we can do 5*3 = 15

f(x) = x(x - a)3(x - b)2
f(x) = 4(x-a)(x - b)2
f(x) = x2 (x-a)5 (x-b)
Answer:
f(x) = x2 (x-a)5 (x-b)
Step-by-step explanation:

The equation of the graph of the polynomials is f ( x ) = x² ( x - a )⁵ ( x - b )
What is Equation of Graph of Polynomials?Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.
Identify the even and odd multiplicities of the polynomial functions' zeros.
Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.
The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities
Given data ,
Let the function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = x² ( x - a )⁵ ( x - b )
From the graph of the polynomial , we can see that
The critical points of the function f(x) = x² ( x - a )⁵ ( x - b ) are x = 0, x = a, x = b, and x = (7a + 5b)/3
Hence , the function is f ( x ) = x² ( x - a )⁵ ( x - b )

Solve the equation 3m – 10 = 5. Find the value of m
Answer:
So I don’t know if this is right cause yeha but I think that m=5
Step-by-step explanation:
we can substitute different numbers starting with one
Or this is the way I did we can do 10+5 which = 15
So that means 15/3=5
So m=5
also I don’t know if this is correct….:/
Answer:
m=5
Step-by-step explanation:
step 1:letters to the left side of the =, numbers to the right (If there are numbers attached to the letter, keep it on the left) if a number is being taken to the right, change the sign to the opposite of what it was
3m= 5+10
step 2: add the numbers on the right
3m=15
step 2: divide both sides by 3 to get m alone
m=5
