Hello there! For this case, in order to simplify the expression, all you have to do is the distributive property. 4 is outside of the parenthesis, so we must multiply that by the terms in the parenthesis. 4 * 7x is 28x. 4 * 5y is 20y. There are no like terms in this case, so it stays put. There. The expression simplified is 28x + 20y.

In ABC the measure of angle a is 2X +3 the measure of angle B is 4X +2 and the measure of angle C is 2X-1 what are the measures

Novay_Z [31]

Angle A is 2x + 3
Angle B is 4x + 2
Angle C is 2x - 1

The three angles add up to 180
So:
2x + 3 + 4x + 2 + 2x - 1 = 180
Combine terms
8x + 4 = 180
Subtract 4
8x = 176
x = 22

Now we solve for the angles:
Angle A is 2(22) + 3 = 44 + 3 = 47
Angle B is 4(22) + 2 = 88 + 2 = 90
Angle C is 2(22) - 1 = 44 - 1 = 43

Quick check: 47 + 90 + 43 = 180
