Answer:
2(2x) - 2(9)
Step-by-step explanation:
this equation could've been distributed many different ways but this is the easiest way I can think of to undistribute this problem. I have never heard of undistributeing a problem either so that must be something knew they are teaching kids.
Answer:
D
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = 0.5h(a + b)
where h is the perpendicular height and a, b the parallel sides.
Given A = 120, then
0.5 × 8(a + b) = 120, that is
4(a + b) = 120 ( divide both sides by 4 )
a + b = 30 cm → D
y = x^2+5x-6 is the answer.
