Answer:
-2x-5
Step-by-step explanation:
Answer:
x = 31
Step-by-step explanation:
The given angles are supplementary and their sum is 180 degrees
5x - 16 + x + 10 = 180 add like terms
6x - 6 = 180 add 6 to both sides
6x = 186 divide both sides by 6
x = 31
Answer:
See my explanation.
Step-by-step explanation:
y=-2
Answer:
16
Step-by-step explanation:
(b/2)^2
(8/2)^2 = (4)^2 = 16
(x^2+8x+16) = -3+16
(x+4)^2 = 13
so on so forth, but basically you add 16 which completes the square
