If three times a number plus four is no more than four times the number minus one, which of the
following are true? Let z represent the number
z>5
225
z 55
The number is at least 5.
The number is at most 5.

c. (3,2,6) is the answer.

1st integer x

2nd integer x+1

3rd integer x+2

4th integer x+3

x+x+1 +x+2+x+3 =74

combine like terms

4x+6 = 74

subtract 6 from each side

4x = 68

x = 17

the integers are 17,18,19,20

so the rectangle is 80cm (area)

now to find the area of a triangle.

4 times 8.

your answer is 96cm.

hope this .
