Step-by-step explanation:
Given
5x + 2x + 2 = 9x + 4
9x - 5x - 2x = 2 - 4
9x - 7x = - 2
2x = - 2
x = - 2 / 2
Therefore x = -1.
Step-by-step explanation:
surface area of cylinder =
2πr(r+h)
2×<u>2</u><u>2</u>×7(7+5)
7
44(7+5)
44(12)
528
%change=100(final-initial)/initial
In this case:
%change=100(3.18-2.56)/2.56
%change=100(0.62)/2.56
%change=62/2.56
%change=775/32%
%change=24.21875%
%change≈24% (to nearest whole percent)
The perimeter of the triangle is 3x + 18 yw
