h(x) = (-4x – 3)(x – 3)
lesser x =
greater x =
Answer:
x = -3/4 or x = 3
Step-by-step explanation:
Solve for x over the real numbers:
(-4 x - 3) (x - 3) = 0
Hint: | Find the roots of each term in the product separately.
Split into two equations:
-4 x - 3 = 0 or x - 3 = 0
Hint: | Look at the first equation: Divide both sides by the sign of the leading coefficient of -4 x - 3.
Multiply both sides by -1:
4 x + 3 = 0 or x - 3 = 0
Hint: | Isolate terms with x to the left hand side.
Subtract 3 from both sides:
4 x = -3 or x - 3 = 0
Hint: | Solve for x.
Divide both sides by 4:
x = -3/4 or x - 3 = 0
Hint: | Look at the second equation: Solve for x.
Add 3 to both sides:
Answer: x = -3/4 or x = 3
Answer:
lesser x = -3/4
greater x =3
Step-by-step explanation:
h(x) = (-4x – 3)(x – 3)
Set the function equal to zero to find the zeros
0 = (-4x – 3)(x – 3)
Using the zero product property
0 = (-4x – 3) 0=(x – 3)
Solve each equation
3 = -4x 3 =x
-3/4=x 3 =x
lesser x = -3/4
greater x =3

The area of a rectangle is represented by the formula A = lw, where I is the length
and w is the width. Solve the formula(equation) for width(w). *
Answer:
w= A / l
Step-by-step explanation:
A = lw
Where,
A= Area of a rectangle
l= Length of a rectangle
w= width of a rectangle
Area of a rectangle = length × width
Solve the formula(equation) for width(w).
A= lw
Divide both sides by l
A / l = lw / l
A / l = w
Width = Area of the rectangle / length of the rectangle
Example: Find the width of the rectangle with length of 6 inches and Area of 12 square inches.
A= 12 square inches
l= 6 inches
w= x inches
A= lw
w= A / l
= 12 / 6
= 2
w = 2 inches
Triangle ABC is shown below. Triangle A B C is shown. The length of side A B is 2 x, the length of side B C is 4 x minus 10, and the length of side A C is 3 x minus 7. Angle A B C and B C A are congruent. What is the length of line segment AC? 7 9 14 18
The length of line segment AC of the given triangle is; 14
How to find the length of the line segment?Since Angle ABC and BCA are congruent, it means that they are equal.
An isosceles triangle is a triangle that has two equal sides and two equal base angles.
Now, since Angle ABC and BCA are equal, it means that the triangle is an isosceles triangle. It also means that sides AC and AB are equal. The expression becomes;
3x - 7 = 2x
3x - 2x = 7
x = 7
To determine the length of line segment AC. We will substitute x = 7 into 3x - 7. It becomes
(3 × 7) - 7
= 21 - 7 = 14

Liam's breakfast was an egg and cheese biscuit with a carton of milk. He spent a total of $5.65. Finn spent $7.65 on an egg and cheese biscuit and two cartons of milk. How much was an egg and cheese biscuit?
Answer:
An egg and cheese biscuit was $3.65.
Step-by-step explanation:
Liam's breakfast was:
[tex] P = E + C + M [/tex]
Where:
P: total price
E: egg
C: cheese biscuit
M: carton of milk
[tex] P = E + C + M [/tex]
[tex] 5.65 = E + C + M [/tex] (1)
Now, Finn's breakfast was:
[tex] P = E + C + 2*M [/tex]
[tex] 7.65 = E + C + 2*M [/tex] (2)
By subtracting equation (2) from (1) we have:
[tex] 7.65 - 5.65 = 2M - M [/tex]
[tex] M = 2 [/tex]
Hence, the price of a carton of milk is $2, so by entering this value into equation (1) we can find the price of an egg and cheese biscuit:
[tex] 5.65 = E + C + M [/tex]
[tex] 5.65 - 2 = E + C [/tex]
[tex] E + C = 3.65 [/tex]
Therefore, an egg and cheese biscuit was $3.65.

How many dots would be in the 7th picture ?
Answer: 28 dots
Step-by-step explanation: In this pattern,
we can see the the first figure is just 1 dot.
The second figure has a new row on the bottom with 2 dots.
The third figure has a new row on the bottom with 3 dots
and the fourth figure has a new row on the bottom with 4 dots.
So continuing with this pattern,
the next figure will have a new row with 5 dots,
the next will have a new row with 6 dots,
and the next will have a new row with 7 dots.
So in the 7th picture, we will have 7 + 6 + 5 + 4 + 3 + 2 + 1 dots.
This simplifies to 28 dots.

You install 404 feet of fencing along the perimeter of a rectangular yard.
The width of the yard is 100 feet. What is the length of the yard?
Answer:
The length of the yard is 102
Step-by-step explanation:
If the width of the yard is 100 feet, and it's a rectangular, that means the other side of the rectangle is also equal to 100 feet. So so far we have 200 feet of the yard covered. Then we do 404-200=204. So the combined length of both the sides is 204. Since they both equal the same length, we can then do 204/2 to get 102. So one side length is 102 and the L, W, L, W of the rectangle is 102, 100, 102, 100. In other words, the rectangle is 102 by 100.
Answer:
Length of the yard = 102 ft
Step-by-step explanation:
Perimeter of the yard P = 404 ft
Width of the yard W = 100 ft
Find Length of the yard L = ?
Perimeter of a rectangular = 2L + 2W
404 = 2L + 2(100)
2L = 404 - 200
2L = 204
L = 204 / 2
L = 102 ft
