Answer:
The length as an algebraic expression in y is 
ft
Step-by-step explanation:
The measure of the width of the computer desk = y feet
The measure of the length of the desk = width + 2 1/4 ft
⇒Measure of Length = ft
Hence, the length as an algebraic expression in y is ft
Answer:
-x^2+5x+3
Step-by-step explanation:
Remove unnecessary parenthesis.
3x-2-x^2+2x+5
Collect like terms.
5x+3-x^2
Use the commutative property to reorder the terms.
-x^2+5x+3
Answer:
30 units
Step-by-step explanation:
If the w=5 and we know that the length is 2(5)=10
For perimeter, there are two sides.
2(10)+2(5)=30 units
Answer:
165°
Step-by-step explanation:
Find the interior angle measure by using the formula, ((n - 2) x 180°) / n
Plug in 24 as n:
((n - 2) x 180°) / n
((24 - 2) x 180°) / 24
(22 x 180°) / 24
3960 / 24
= 165
So, the measure of each angle is 165°
