the proportion is true
Answer:
Length= 30 in
Width= 10 in
Step-by-step explanation:
Let the width of the rectangle be x in.
Length of rectangle
= 3 (width)
= 3x
Perimeter of rectangle= 2(length) +2(width)
80= 2(3x) +2(x)
80= 6x +2x
8x= 80 <em>(</em><em>simplify</em><em>)</em>
x= 80 ÷8 <em>(</em><em>÷</em><em>8</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
x= 10
Thus width of rectangle= 10 in
Length of rectangle
= 3(10)
= 30 in
Both A and C is true. However, even though a rectangle can be a parallelogram, a parallelogram is a quadrilateral, so the answer is A.
I hope this helps!
Answer: PSR (Perfect Square Rule) = (x-3/2)^2
The you simplify.... = x^2 - 3x + 9/4
Step-by-step explanation: Factor by using the PSR (Perfect Square Rule). Then you have to simplify.
Hope this helps you out! ☺
