B = 2 + 2H
A = 20 ft^2
H = H
Since the Area of a Triangle is Base * Height then the formula should be:
A = BH
20 = H(2+2H)
20 = 2H^2 + 2H
0 = 2H^2 + 2H - 20
Find the zeros of the quadratic equation through substituting the values of a,b, and c. You will get the zeros of x = 2.7 and -3.7. The only thing that would make sense is you use the x=2.7 because there are no negative heights.
Since b = 2h+2
b= 2(2.7) + 2
b= 5.4 + 2
b=7.4
I don't know where you got 4 and 10, but what I got is different.
You have the slope and you have two points, so you can use the slope equation to find x.

So your answer is x = 8.
Answer:
41,6 cm
Step-by-step explanation:
Formula for Perimeter of a rhombus: P = 2L + 2H (H is the height, L the length)
Perimeter: 160 cm = 2L + 2(38,4 cm), or
160 cm + 76.8 cm + 2L, or
83.2 cm = 2L
and so the height (altezza) is H = 83.2 cm / 2 = 41,6 cm
