Area: 5x² + 7x - 26, Answer C.
To solve the area if the shaded region, let's find the are of the whole figure then find the area of the open rectangle in the center and find the difference of them both.
(3x - 4)(2x + 2)
6x² - 8x + 6x - 8
<span>6x² - 2x - 8
</span>Next, let's solve the area of the open rectangle in the center of the shaded region.
<span>
(</span>x - 6)(x - 3)
x² - 6x - 3x + 18
x² - 9x + 18
Now, let's take the difference between both the areas.
(6x² - 2x - 8) - (x² - 9x + 18)
6x² - 2x - 8 - x² + 9x - 18
5x² + 7x - 26
Answer:
x = 10
x = -2
Step-by-step explanation:
I'll solve it.
Open parentheses:
x^2 - 8x + 15 = 35
x^2 - 8x - 20 = 0
(x - 10)(x + 2) = 0
x = 10, x = -2
Answer:
Correct choice is D). 8y + 96.
Step-by-step explanation:
Given expression is .
Now question says to simplify that expression using distributive property then find the correct matching choice from the given choices:
A). 8y=12
B). 20y
C). 20 - y
D). 8y + 96
So let's distribute 8 by using distributive property
Hence correct choice is D). 8y + 96.
You have to divide by both sides to get the answer
