Answer:
5x+9 = 109
3x+11 =71
Step-by-step explanation:
A linear pair adds to 180
5x+9 + 3x+11 =180
Combine like terms
8x + 20 =180
Subtract 20 from each side
8x +20-20 = 180-20
8x = 160
Divide each side by 8
8x/8 = 160/8
x=20
5x+9 = 5*20+9 = 100+9 = 109
3x+11 = 3*20+11 = 60+11=71
100= 10^2.
The missing exponent is 2~
Answer:
Top left: x^2 +8x +15
Top right: x^2 +3x -18
Bottom left: x^2 -3x -18
Bottom right: x^2 -10x +16
Step-by-step explanation:
So your parent hasn't joined you on the Brainly express to Achievement-ville. We'll get them on board. Parents are busy people, but you can be the boss and remind them.
