Find the area of the figure.

The height is 57.5

Step-by-step explanation:

To find the height, you would use the equation h= 2 a/a+b

So you would insert the numbers and turn the equation into 2(6555/ 123+105)

Then you would solve.

After solving, you will find that H= 57.5

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
