Answer:
Set C
Step-by-step explanation:
4(x-2)-3=9
<span>Reorder the terms:
4(-2 + x) + -3 = 9
</span><span>(-2 * 4 + x * 4) + -3 = 9
</span><span>(-8 + 4x) + -3 = 9
</span><span>Reorder the terms:
-8 + -3 + 4x = 9
</span><span>Combine like terms:
-8 + -3 = -11
</span>-11 + 4x = 9
<span>Solving:
-11 + 4x = 9
</span>Add '11' to each side of the equation.
-11 + 11 + 4x = 9 + 11
Combine like terms: -11 + 11 = 0
0 + 4x = 9 + 11
4x = 9 + 11
<span>Combine like terms:
9 + 11 = 20
4x = 20
</span><span>Divide each side by 4.
x = 5</span>
Answer:
62.8 in
Step-by-step explanation:
formula to find surface area of cylinder = 2πrh + 2πr²
2 × 3.14 × 2 × 3 + 2 × 3.14 × 2²
37.68 + 25.12
62.8 in
The answer would be -0.66
I hope this helps you
12/12+x=13/13+26
12/12+x=13/39
12/12+x=1/3
12+x=36
x=24
