Question

Show all steps. Let a= -1, b = 2, x = -5, y = 4, and w = -10.

Answer 1

5. Given

`a^2-bw`

You know that:

a=-1

b=2

w=-10

Replace these values into the expression:

`(-1)^2-2\cdot(-10)`

Following the order of operations, first, you have to solve the exponent and the multiplication:

`1-(-20)`

Both minus signs form a "double negative" when this happens, the signs cancel each other and turn into a plus sign, so that:

`1+20`

Next, solve the addition

`1+20=21`

The result of this operation is 21.
