Area = length (L) * Width (W)
Perimeter = (2*L) + (2*W)
L*W = 35
W = 35/L
2L + 2W = 27
L+W = 13.5
L + 35/L = 13.5
L^2 + 35 = 13.5L
L^2 - 13.5L + 35 = 0
(L - 10) (L - 3.5) = 0
L = 10 ft or L = 3.5 ft
LW = 35
If L = 10 ft
W = 3.5 ft
Answer:
x=-0.08 and y=2.92
Step-by-step explanation:
123x + 2(x+3) = -4 y = -0.08 + 3
123x + 2x + 6 = -4 = 2.92
125x + 6 = -4
125x = -10
x= -0.08
Answer:
178 sq in
Step-by-step explanation:
Ⓗⓘ ⓣⓗⓔⓡⓔ
Well, we know the formula for finding the area of a rectangle is B*H, and the formula for finding the area of a circle is πr^2
Let's find the area of a rectangle first:
25*6=150 sq in
Now the semicircles {which combined into one whole circle because they're two halves}:
The diameter is 6 inches, so the radius is 3 inches.
π(3)^2=9π
9*π=28.27 which can be rounded down to 28 sq in.
To fin the area of both, we would add them together:
150+28=178 square inches

Please, please give brainliest, it would be greatly appreciated, I only a few more before I advance, thanks!
Answer:
7/5 y --> y+ 2/5y
0.68y --> y - 0.32y
3/5y --> y - 2/5y
1.32y --> y+ 0.32y
Step-by-step explanation:
Pretend there is a 1 in front of each y that doesn't have a number (coefficient) in front of it. 1 = 5/5, and then just solve for the fraction expressions.
2 Gallons = 32 Cups.
32 - 12 (because he served them to his guests)= 20.
20 Cups of soup were left after the party.
