560+ 147= 707
14(40)= 560
14+ 14(1/2)=21
21(7)= 147
Distributive property, since 3(2x) you distribute and get 6x
I’m not sure if this was a typo, but A and B are the same answer. A and B are correct, because when you solve this the answer has to be anything less than -0.6.
Answer:
A = 99 cm²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A =
bh ( b is the base and h the perpendicular height )
Here b = 18 and h = 11 , then
A =
× 18 × 11 = 9 × 11 = 99 cm²
