In short, the set formed by the negative integers, the number zero and the positive integers (or natural numbers) is called the set of integers. Integer is also known as a whole number.
A). They are supplementary angles meaning they add up to 180
So
B) (12x+8)+(3x+7)=180
12x+8+3x+7=180
15x+15=180
-15 -15
15x=165
15/15x=165/15
x=11
Angle 1 is
12x+8
12(11)+8
132+8
140
Therefore measure of angle 1 is 140°
Angle 2
3x+7
3(11)+7
33+7
40
Measure of angle 2 is 40°
-2x*(-3x)-2x*(-4y)-2x*(-8)
answer :6x^2+8xy+16x
Yes based on ja 82 and it can be added
