100 by 65 = 330 perimeter = 6,500 area
90 by 75 = 330 perimeter = 6,750 area
Hi there!
First, we need to find the area of the wallpaper.
42 × 25.5 = 1071
Now, we divide 771.12 by 1071.
771.12 ÷ 1071 = 0.72
So, the wallpaper costs 0.72 dollars per square foot.
Hope this helps!
Ab=750 and a=b-5, using this value of a in the original equation gives you:
(b-5)b=750
b^2-5b=750
b^2-5b-750=0
b^2-30b+25b-750=0
b(b-30)+25(b-30)=0
(b+25)(b-30)=0
b=30
82.66666667 (this rounded) if you want the non rounded version this is the answer:
82.6666666666666666
The 6’s will go on forever so, in your answer you need to put a horizontal line on top of the six:
Ex. _
82.66
Any of these answers are correct, you can choose which to use. The safest answer would be the last one that has the line on top.
Pls mark brainliest :)
