I dont know this. pls help
Answer:
28, 4 or 4, 28 (order doesn't matter, both are true answers)
Step-by-step explanation:
l + w = 32
l*w = 112
l = 112/w
112/w + w = 32
w = 28 or 4
l = 28 or 4
Answer:
4,28
Step-by-step explanation:
So let's look at the sentence to take any necessary information out. It says the length of a rectangle plus it's width is 32. Since we do not know what the length and width are, let's just represent them as L (length) and W (width). Using this information we get the equation: [tex]L + W = 32[/tex] and since we're given the area of the rectangle, we can also define another equation which is: [tex]LW = 112[/tex] since the length * width = area.
So now all we have is a systems of equations. We can solve for L or W in the area equation and plug it into the addition equation. We can also solve for L or W in the addition equation and then plug it into the area equation, either should work, but in this example I'll solve for L in the addition equation:
Original Equation:
[tex]L + W = 32[/tex]
Subtract 32 from both sides
[tex]L = 32-W[/tex]
Now let's use this definition of L to plug into the second equation:
[tex]LW = 112 \implies (32-W)W = 112[/tex]
Distribute the W
[tex]-W^2+32W=112[/tex]
Now if you notice, we simply have a quadratic equation and we can subtract 112 from both sides and then use the quadratic formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
Subtract 112 from both sides
[tex]-W^2+32W-112=0[/tex]
Use quadratic formula
[tex]W = \frac{-32\pm\sqrt{32^2-4(-1)(-112)}}{2(-1)}[/tex]
Simplify stuff in radical
[tex]W = \frac{-32\pm\sqrt{576}}{-2}[/tex]
Calculate the square root
[tex]W=\frac{-32\pm24}{-2}[/tex]
Use positive sign:
[tex]W=\frac{-32+24}{-2}[/tex]
Simplify numerator
[tex]W = \frac{-8}{-2}[/tex]
Simplify fraction
[tex]W=4[/tex]
Take negative sign
[tex]W = \frac{-32-24}{-2}[/tex]
Simplify numerator
[tex]W=\frac{-56}{-2}[/tex]
W = [tex]28[/tex]
So we have two solutions, and the reason for this is because had we solved for W in the original equation and substituted that into here, there would be no different, it's not bound by some variable name. So these are actually the two sides of the rectangles

Step-by-step explanation:
Solution
The length of all the rectangles is 7
You need the width to be 4
Area rectangle = L*w
Area rectangle = 7*4
Area rectangle = 28
Answer: B
The sum of three numbers $a, b$ and $c$ is 60. If we decrease $a$ by 7, we get the value $N$. If we increase $b$ by 7, we get the value $N$. If we multiply $c$ by 7, we also get the value $N$. What is the value of $N$
The value of N is 28.
What is the solution of the equation?A mathematical statement that has a "equal to" symbol between two expressions with equal values is called an equation.
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have LHS = RHS (left hand side = right hand side) in every mathematical equation. To determine the value of an unknown variable that represents an unknown quantity, equations can be solved.
According to the question,
a+b+c=60
a-7=N
b+7=N
7c=N
From the above three equations,
a=N+7
b=N-7
c=N/7
So, N+7+N-7+N/7=60
2N+N/7=60
14N+N=420
15N=420
N=28

What is the distance between the points (22,27) and (2,-10)
Answer:
42.1
Step-by-step explanation:
The formula to calculate distance is √[(x₂ - x₁)² + (y₂ - y₁)²]. Using (22,27) as our x1 and y1, and (2,-10) as our x2 and y2.
Therefore our formula is √[(2 - 22)² + (-10 - 27)²].
(2 - 22)² = 400
(-10 - 27)² = 1369
(Make sure for both of these you put the negative number in parenthesis and the exponent outside them, if you are using a calculator of some sort)
Then we add and square root
√[400 + 1369] = 42.0594816896
The distance between the points (22,27) and (2,-10) is 42.1 units
How to determine the distance between the points?The coordinates of the points are (22,27) and (2,-10)
The distance is calculated as:
[tex]d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2[/tex]
So, we have:
[tex]d = \sqrt{(22 -2)^2 + (27 +10)^2[/tex]
Evaluate
[tex]d = \sqrt{1769[/tex]
Take the square root
d = 42.1
Hence, the distance between the points (22,27) and (2,-10) is 42.1 units

What is a linear equation in math?
A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction. When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line.I spent a dollars at American Eagle, which is 4 more than the amount I spent at Banana Republic ( b ).
a = b + 4. Therefore: b = a - 4
Also I spent 15 less at American Eagle than I spent in Cole Haan ( c ).
a = c - 15, or: c = a + 15.
75 - a - ( a - 4 ) - ( a + 15 ) = 75 - a - a + 4 - a - 15 =

Answer:
X=10
Step-by-step explanation:
You can subtract 180 by 110 to get 70. Then you can do 8x+30+70=180
Add 30+70 to get 100
Subtract 100 to 180 to get 80.
8x=80
You divide 8 from both sides which leaves you with x=10.
