= -1
The answer is = d due to the proportional
Answer:
To find the missing base, you simply divided the area by the given height. This will work the same way if you are looking for the height. To find the missing height, divide the area by the given base. Consider this parallelogram where height is the missing dimension.Oct 30, 2012

Answer:
That would be :
4x – 10 = x2 – 5x + 10 ( y = 4x - 10 is substitute for y)
PROOF: y + 5x = x² + 10
(4x - 10) + 5x = x² + 10
4x - 10 = x² -5x + 10
0 = x2 – 9x + 20 (liked terms are grouped and simplified)
PROOF: 4x - 10 = x² -5x + 10
4x = x² -5x + 10 + 10
0 = x² -5x -4x + 20
0 = x² - 9x + 20
Solving:
x² - 9x + 20 = 0
x² - 5x - 4x + 20 = 0
(x - 5) (x - 4) = 0
⇒ x = 4 (as question says) OR x = 5

Answer:
185.04 mm
Step-by-step explanation:
The perimeter is 1/2 of the circumference plus the diameter
We need to go around the semicircle on the outside plus across the middle
1/2 C + d
1/2 2*pi * r + 2r
pi *r +2r
3.14 (36) + 2 (36)
113.04+72
185.04
