Explain why each of the following triangles has an area of 9 squared units

Some of them which have halves count too

Step-by-step explanation:

So 2 halves together = 1

Try counting now.

They may have different base, they may have different altitude (h). They will have same area if all triangles using the formula 1/2 x base x altitude equals

Step-by-step explanation:

Please give me brainliest :D

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )

if x decreases by 4 then y increases by 10
