7. what are possible dimensions of the rectangular area at the right? area = 27x - 9
Answer
Explanation:
Step1: Factor the area expression
Factor out the greatest - common factor of (27x - 9). The GCF of 27 and 9 is 9. So, (27x-9 = 9(3x - 1)).
Step2: Recall the area formula for a rectangle
The area of a rectangle is (A = l\times w), where (l) is the length and (w) is the width. If (A=9(3x - 1)), then possible dimensions of the rectangle are a length of 9 and a width of (3x - 1) (or vice - versa).
Answer:
The possible dimensions of the rectangle are 9 and (3x - 1).
