Solve the inequality.

8x + 9 < 4x − 3
a) x < 3
b) x <
3
2
c) x < −3
d) x < −
3
2

x <-3

Step-by-step explanation:

8x + 9 < 4x − 3

Subtract 4x from each each

8x -4x + 9 < 4x -4x − 3

4x +9 < -3

Subtract 9 from each side

4x + 9-9 <  − 3-9

4x< -12

Divide by 4

4x/4 < -12/4

x <-3

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are
