Step-by-step explanation:
given we want to solve for a
How?
We can do this by using basic algebra ( isolating the variable (a ))
Step 1 subtract from each side
now we have
step 2 take the square root of each side
we're left with
Hence your answer is A
Answer:
The expression for the length of the rectangle is 2x + 4
Step-by-step explanation:
The formula for determining the area of a rectangle is expressed as
Area = length × width
The area of a rectangle is expressed as (14x + 28) square feet. If the width of the rectangle is 7 feet, then the expression for the length of the rectangle would be
Length = Area/ width
= (14x + 28)/7
The numerator has a common factor of 7. Therefore, if we factorize 7 out, it becomes
7(2x + 4)/7
Length = 2x + 4
