42 is 15
Step-by-step explanation:
42 is 15 because of x
The formula of a trapezoid is the sum of the both bases multiplied by the height then divided by 2.
Answer:
x = 1
Step-by-step explanation:
Line of symmetry: x = h,
Where h is the x-coordinate of the vertex
your answer would be c) 9
set up an equation for the perimeter
l = length w = width
2l + 2w = 64
set up another equation as you know the length is 3 times the width
w = 3l
subsitute w = 3l into the 2l + 2w = 64
2l + 2(3l) = 64
solve for l
2l + 6l = 64
8l = 64
<em><u>length</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>8</u></em>
subsitute into w = 3l
w = 3(8)
<em><u>width</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>2</u></em><em><u>4</u></em>
