Answer:
see below
Step-by-step explanation:
1st: x
2nd: 5x + 8
x(5x + 8) = 36
5x² + 8x = 36
5x² + 8x - 36 = 0
(x - 2)(5x + 18) = 0
(x - 2) = 0
x - 2 = 0
x = 2
1st: x = 2
2nd: 5x + 8 = 5(2) + 8 = 18
(5x + 18) = 0
5x + 18 = 0
5x = -18
x = -3.6
1st: x = -3.6
2nd: 5x + 8 = 5(-3.6) + 8 = -18 + 8 = -10
Answer:
The solution for the other side length is the interval
(2.5,6.5)
Step-by-step explanation:
I will assume that is a triangle
we know that
The <u><em>Triangle Inequality Theorem</em></u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
Let
x ---> the measure of the third side
Applying the Triangle Inequality Theorem
1) 

Rewrite

2) 

therefore
The solution for the other side length is the interval
(2.5,6.5)
120 for the 4 pair of jeans, 30 for the 2 pair of shirts, 60 for the 3 pairs of shorts. He had spent 210 on his clothes.
38 shelves.
i say this because if you divide 34 and 1265 you get 38 r 7. you need to fill in all the books so just add one more shelf.
~hope this helped
