Define Length and Width
---------------------------------------------------------------------------------
Let the width be x
Width = x
Length = 2x + 5
---------------------------------------------------------------------------------
Form equation and solve for x
---------------------------------------------------------------------------------
x(2x + 5) = 63
2x² + 5x = 63
2x² + 5x - 63 = 0
<span>(x+7)(2x-9) = 0
</span>x = -7 (rejected, length cannot be negative) or 2x - 9 = 0
2x - 9 = 0
2x = 9
x = 9 ÷ 2
x = 4.5 ft
---------------------------------------------------------------------------------
Find Length and Width
---------------------------------------------------------------------------------
Width = x = 4.5 ft
Length = 2x + 5 = 2(4.5) + 5 = 14 ft
---------------------------------------------------------------------------------
Answer: Width = 4.5 ft , Length = 14 ft
---------------------------------------------------------------------------------
Subtract 5x from each side. Then you have
y = 6 - 5x .
IDK
YOU KNOW THOUGH RIGHT>
Sorry mate, I can help with 8.) and 9.)
8.) angle T=180-(21+35)
T=180-56
T=124
Angle V=124
Triangle TUV is an isosceles triangle therefore, it has two equal sides and two equal angles.
9.) Angle WSV=21 degree
Triangle TSV is an isosceles triangle therefore, it has two equal sides and two equal angles.
TSV=21+21=42 degree
Had to run, can’t do rest. Hopefully, this helped a bit. Good luck.
Answer:
Brand A is the better buy with unit rate $4/cup.
Step-by-step explanation:
Given:
Brand A 33 fluid ounce bottle = $16.50
Brand B 1 cup = $4.80
We need to find the unit cost and find which is the better buy.
Solution:
For Brand A;
33 fluid ounce = $16.50
1 fluid ounce = Cost for 1 fluid ounce
By using Unitary method we get;
Cost for 1 fluid ounce = 
Now we know that;
1 cup = 8 fluid ounce.
1 fluid ounce = $0.5
8 fluid ounce = Cost for 8 fluid ounce of olive oil.
Again By using Unitary method we get;
Cost for 8 fluid ounce of olive oil = 
Hence Brand A 1 cup of olive oil cost $4.
For Brand B;
Given:
1 cup of olive oil =$4.80
Hence Brand B 1 cup of olive oil cost $4.8.
By Comparing both brands we can see that per unit cost of Brand A is less than Brand B.
Hence Brand A is the better buy.
