Answer:
x = 126
Step-by-step explanation:
The angles are complementary which means they sum to 180
x+54 =180
x = 180-54
x = 126
I think that’s it (x+4) (x+5)
2x + -7 +8 = -x+16
2x + 1 = -x +16
2x +1 -1= -x +16 -1
2x+x = -x +x + 15
3x = 15
3x/3 = 15/3
x= 5
2(5) + -7 +8 = -5+16
10 +-7+8 = 11
11=11
Answer:
20.
Step-by-step explanation:
2x + x - y^2; x = 8 and y = 2.
2(8) + 8 - (2)^2
= 16 + 8 - 4
= 24 - 4
= 20.
Hope this helps!
