I believe your answer is 8.
Three times a number less than twice the number and nine is seventeen can be written as: 3n - 2n + 9 = 17
Solve for n as follows:
3n - 2n = n
n + 9 = 17
17 - 9 = 8

Answer:
28
Step-by-step explanation:
The formula for trapezoid area is [(b1+b2)/2]h where the b's are the bases and the h is the height. Plugging the values in, you get 28. Have a good day!
We can find the length of this side with
AB² = BC² + AC²
where AB is the length, BC is the width and AC is the height
AB² = 10² + 8²
AB² = 100 + 64
AB² = 164
AB = √164
AB = 12.81
or
AB = 12.8
Answer:
The area of the original square = 100 inches²
Step-by-step explanation:
The picture below is the complete image required to answer the question. The picture below was trimmed below as 5 inches was cut from the width and 6 inches from the length.
The cut picture area = 20 inches²
Therefore,
(x - 6)(x - 5) = 20
x² - 5x - 6x + 30 = 20
x² - 11x + 10
The factors are -10 and - 1
x² - x - 10x + 10 = 0
x(x - 1) - 10(x - 1) = 0
(x - 10)(x - 1) = 0
x = 10 or 1
10 is more appropriate as we will get a positive number if inserted in the equation.
(x - 6)(x - 5) = 20
(10 - 6)(10 - 5) = 20
4 × 5 = 20
x = 10
The area of the original square = L²
The area of the original square = 10²
The area of the original square = 100 inches²
