X, X+2, X+4 ARE THE 3 POSITIVE CONSECUTIVE INTEGERS.
X(X+2)=8+38(X+4)
X^2+2X=8+38X+152
X^2+2X-38X-8-152=0
X^2-36X-160=0
(X-40)(X+4)=0
X-40=0
X=40 ANSWER FOR THE FIRST INTEGER.

Answer:
width = 20
length = 28
Step-by-step explanation:
perimeter=96
width=x
length=x+8
(length*2) + (width*2) = perimeter
2(x+8) + 2(x) = 96
2x+16+2x=96
4x+16=96
4x=80
x=20
width = 20
length = 28
Answer:
18%
Step-by-step explanation:
We know that currently 20% of city employees ride the bus to work. The problem states that there was a 10% increase from last year. To figure out this answer, we need to find out how much 10% of 20% is. Knowing what we know, lets now convert the percentages to decimals so we can do this math easier.
- 20% converted to a decimal is 0.2
- 10% converted to a decimal is 0.1
To find 10% of 20%, we simply multiply (0.2) x (0.1) which equals 0.02. In other terms, this is 2%. We now know that since last year, the percentage of city employees riding the bus went up 2%. This means that if we simply subtract 2 from 20 we get 18...
Last year, 18% of city employees rode the bus to work.
