The rectangle below has an area of 49-x^2 square meters and a width of 7+x. What expression represents the length of the rectang le?
2 answers:
49-x^2 factors to (7+x)(7-x). This is because both terms are perfect squares. When you divide out 7+x because a rectangle's area equals length times width, you get 7-x Final answer: 7-x
Answer:
( 7-x ) meter.
Step-by-step explanation:
Rectangle has an area of and width of the rectangle is given as ( 7 + x).
We have to find expression that represents length of the rectangle.
Since area of rectangle = Length × width
× length
× length
[Since
Length =
= (7-x) meter
