Answer:
7 1/2
Step-by-step explanation:
25 = 5.2 + 8 + x
5.2 + 8 = 13.2
25 = 13.2 + x
25 - 13.2 = 11.8
11.8 = x
The unknown side is 11.8 ft.
The formula for the area of a triangle is 1/2(base×height)
30×27=810
810×1/2=405
The simplified expression of 32/5 x 3(-7/5) is -672/25
<h3>How to simplify the expression?</h3>
The mathematical expression is given as:
32/5 x 3(-7/5)
Evaluate the product of 3 and -7/5
32/5 x 3(-7/5) = 32/5 x -21/5
Evaluate the product of 32 and -21
32/5 x 3(-7/5) = 672/5 x -1/5
Evaluate the product of 5 and 5
32/5 x 3(-7/5) = 672/25 x -1
So, we have:
32/5 x 3(-7/5) = -672/25
Hence, the simplified expression of 32/5 x 3(-7/5) is -672/25
