Why is the number zero so important in our math system? How would our math system be affected if there were no such thing as zero?

Step-by-step explanation:

The number zero is important because, For example, lets say it was 50+76

we NEED that zero else it would me 5+76 then, you woudn't get the right answer.

Hope this helps you! <3

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 : )

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
