Answer:
a) (2x+7)(x-4)
b) x = -7/2 and x = 4
Step-by-step explanation:
a) (2x ?)(x ?)
set up the above and considered factors of 28 that, when paired with 2, would give me -1x and -28 → (1·28, 2·14, 4·7)
after trial-and-error, found that 4 and 7 worked (used un-FOIL)
b) 2x + 7 = 0
2x = -7
x = -7/2
*********
x-4 = 0
x = 4
Answer: 18.8 miles
Step-by-step explanation:
Ww are given the equation 4.7x=2.5x+8.8 to solve the question. This will be:
4.7x = 2.5x + 8.8
Collect like terms.
4.7x - 2.5x = 8.8
2.2x.= 8.8
x = 8.8/2.2
x = 4
To know how fast the kickers are going will be
4.7x = 4.7 × 4 = 18.8 miles
Answer:
lw/4
Step-by-step explanation:
Area of a rectangle = length × width
= l × w
Area of a rectangle = let
reduce the area of his rectangular garden by one-fourth
= 1/4 * lw
= 1/4lw
What is another way to write this expression?
Another way to write the expression is
= 1/4 * lw
= lw / 4
<span>x = 9
Since ZP bisects â OZQ, that means that the measurements for â OZP and â PZQ are the same. So create an equation with their respective values set to each other.
8x - 9 = 5x + 18
Now solve for x
8x - 9 = 5x + 18
Subtract 5x from both sides
3x - 9 = 18
Add 9 to both sides
3x = 27
Divide both sides by 3
x = 9</span>
It's C.
multiply by 3
x = 4, y = 4x3 = 12
x = 5, y = 5x3 =15
x = 6, y = 6x3 =18
