Answer:
Surface area of cylinder
A=2πrh+2πr²
= 2×3.14×5×12 + 2×3.14×5²
Surface area = 534.07 cm²
We know that we can take 4 out of (-16x + 8) [ we know this because we can divide 16 by 4 ( to get 4 ) and we can divide 8 by 4 ( to get 2 ) ]
we can factor out a 4 then from the parentheses to get 4(-4x + 2), but since we are multiplying by 1/4 we get
1/4(4)(-4x + 2), and since 1/4 * 4 = 1, our final answer is
-4x + 2
Answer:
y = ± sqrt(x+7)
Step-by-step explanation:
y = x^2 -7 solve for 'x' .... add 7 to both sides
y+7 = x^2 sqrt both sides
+- sqrt(y+7) = x switch 'x' and 'y'
y = +- sqrt(x+7)
