Answer:
18x - 3
Step-by-step explanation:
Add all the X values
8x + -2x + 12x = 18x
Put the final numbers on the side.
-3
18x-3
1.5/4 is shaded, since there is one block shaded, and half of another block (1.5)
The function in this problem should be: <span>f(x) =x</span>² <span>+ 12x + 6
y = x</span>² + 12x + 6
y - 6 = x² + 12x
x² ⇒ x * x
12x ⇒ 2*6*x
missing number is 6² = 36
y - 6 + 36 = x² + 12x + 36
(x+6)(x+6) ⇒ x(x+6)+6(x+6) ⇒ x² + 6x + 6x + 36 = x² + 12x + 36
y + 30 = x² + 12x + 36
y = (x+6)² - 30
Choice is D. 36,-36
I think it'd be 10in. If you cut it into three parts, where the bottom is sectioned off from the other two rectangles, the two rectangles on the side both have an area of 3in, so together they'd be 6in. The rectangle on the bottom has a length of 4 and a width of 1, so it'd be 4in... add those together and get 10in. Hope this helps
