What is the change in elevation between 8,500m and -300m

The change in elevation is 5,100 m.

Step-by-step explanation:

Since we have given that

Initial height = 8,500 m

New height = 3,400 m

We need to find the change in elevation:

As we know the change in elevation is the difference between the heights:

So, it becomes,

8500-3400

=5,100 m

Hence, the change in elevation is 5,100 m.

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
