Simplify the expression
4(w+2x)+9(-4w)

=−32w+8x

Step-by-step explanation:

4(w+2x)+9(−4w)

Distribute:

=(4)(w)+(4)(2x)+9(−4w)

=4w+8x+−36w

Combine Like Terms:

=4w+8x+−36w

=(4w+−36w)+(8x)

=−32w+8x

step-by-step explanation:

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 .
