use the Pythagoras theorem method
a squared plus b squared equals c square
Expression for perimeter is 2(14-x + x) = 28
<u>Step-by-step explanation:</u>
Step 1:
Given expression for area of the rectangle = a(x) = x(14-x) where x is the width. Then length = 14-x since area = length × width
Step 2:
Find expression for perimeter of the rectangle.
Perimeter of the rectangle = 2(length + width) = 2(14 - x + x) = 2 × 14 = 28
25 and 1/4 thats the answer
Answer:
x = 5/9
Step-by-step explanation:
1/3 +x = 8/9
We need to get a common denominator of 9
1/3 * 3/3 +x = 8/9
3/9 + x = 8/9
Subtract 3/9 from each side
3/9 - 3/9 +x = 8/9 - 3/9
x = 5/9
