Perimeter = 2(Length) + 2(Width)
300 = 2L + 2W → 150 = L + W → 150 - L = W
Area = Length · Width
= L(150 - L) → = 150L - L²
There are 2 different methods for solving (depending on which math course you are taking).
<u>Calculus</u>: find the derivative, set it equal to zero, and solve for L.
= 150L - L² → 0 = 150 - 2L → 2L = 150 → L = 75
<u>Algebra</u>: find the vertex.
= - L² + 150L → L = -b/2a → L = -150/2(-1) → L = 75
Once you solve for L, plug it into the Perimeter equation to solve for W:
150 - L = W → 150 - 75 = W → W = 75
Answer: 75ft x 75ft
It says it clearlyit says it must include appetizers a main course dessert beverage and water
Step-by-step explanation:
The variables w, x, and z are not needed because this expression only contain one variable, y
y= 5 It says it in the problem
Start by substituting the value of y into the expression
y+5 = 5+5
Solve
5+5 = 10
Solution: y+5 = 10

Answer:
next to the seven would be 2 and before the 4 would be 14
Step-by-step explanation
Find how much fabric it takes to make one cloak, 21/6=3.5
To find the answer in the second row you see how many times that amount of fabric goes into 7. 7/3.5=2
To find the answer to the third row multiply the amount of fabric it takes to make one cloak, 3.5, by 4, the amount of cloaks. 3.5x4=14
