What is the simplified form of the quantity 9 x squared minus 25 over the quantity 3 x plus 5?
eimsori [14]
It would be: 9x² - 25 / 3x + 5
We can write 9x² - 25 as (3x + 5)(3x - 5)

So, = (3x + 5)(3x - 5) / 3x + 5
= 3x - 5

In a group of 100 adults, 70 say they are most likely to do spring houseclean-ing in March, April, or May. Of these 70, the numb
son4ous [18]

Answer:

Adults that clean in March = 18

Adults that clean in April = 48

Adults that clean in May = 4

Step-by-step explanation:

Adults that clean in the months of March, April and May = 70

Let a represent March, b represent April and c represent May.

Therefore, a + b + c = 70     (i)

From the question, the number of adults that clean in April is 14 more than number of the adults cleaning in months of March and May combined.

b - ( a + c) = 14      (ii)

also, the total number who clean in April and May is 2 more than three times the number who clean in March.

b + c - 3a = 2     (iii)

From (i), a + c =   70 - b (iv)

Substituting (iv) into (ii), b - ( 70 - b) = 14

b -70 + b = 14

2b = 84, b =48

Therefore a + c = 70 - 48

a + c = 22; c = 22 - a   (v)

Substituting (v) and b = 48 into (iii)

48 + 22 - a -3a = 2

4a = 72, a = 18

Therefore, c = 22 - 18

c = 4
