C.110 hopefully that's the right answer
Answer:
This is probably wrong. But i hope this helps anyways
Step-by-step explanation:
If the perimeter is twice its width, and the perimeter is 60. That means the whole length of the shape youre looking at is 120. (60•2) we can assume that this shape has 4 sides. 60/4. Thats 15. So the sides are 4 ft. The length is at the top and bottom is 15. 15•4 = 60. There ya go
Answer:
x = 20
Step-by-step explanation:
the angles shown are supplementary
supplementary angles add up to 180°
hence, 5x - 7 + 3x + 27 = 180
==> combine like terms
8x + 20 = 180
==> subtract 20 from both sides
8x = 160
==> divide both sides by 8
x = 20
Answer:
x = 4 or x = 0.78
Step-by-step explanation:
9x² – 29x – 28 = 0
2 roots: x = ((-(-29) ± √(-29)² - 4 x 9 x (-28)) / (2 x 9)
= (29 ± √841 + 1008) / 18
= (29 ± 43) /18
x = 72 /18 = 4 or
x = -14 /18 = - 0.78
