Answer:
18, the answer to 8+10 is 18, like you learn in 1st grade
Answer:
y = 5x^2+10x +14
Step-by-step explanation:
y = 5(x+1)^2+9
= 5(x^2+2x+1)+9
= 5x^2+10x +14
X = 60°
Because the square in the corner tells you that it is 90° (right angle)
So your equation to solve for x would be...
x + 30 = 90
Now you need to isolate the x.
Subtract both sides by 30.
x + 0 = 90 - 30
x = 60
X-9=8(2x+3)-18
x-9=16x+24-18
-9=15x+6
-15=15x
x=-1
If the diameter of the cylinder's base is 10, then the radius is half that, or 5.
