(4)=34 (3/2)=67 sorry if I am wrong.
Answer:
5 ft
Step-by-step explanation:
The area of a trapezoid is given by the formula ...
A = 1/2(b1 +b2)h
The height is found by solving this equation for h:
2A/(b1 +b2) = h
h = 2(25.5)/(3.2 +7) = 51/10.2 = 5 . . . . fill in the given values
The height of the trapezoid is 5 feet.
3% x 10 years is 30%. 47 - 30% is 14.1 or 14
X² - 10x = 46
10/2 = 5; 5²+ 25 add 25 to both sides
x² - 10x + 25 = 46 + 25
so the number you have to add to complete the square is 25.
