Answer:
B
Step-by-step explanation:
Its 210,750 i took the quiz. You have to plug in 750 to all the x's.
Answer: w ≤ 14 cm , L ≤ 42 cm
<u>Step-by-step explanation:</u>
width (w): w
Length(L): 3w
Perimeter (P) = 2w + 2L
P ≤ 112
2w + 2L ≤ 112
2(w) + 2(3w) ≤ 112
2w + 6w ≤ 112
8w ≤ 112
w ≤ 14
First you will have to use the equation length*width*height. The just plug in 4 for the height, then since the length is 4 times longer plug in 4x, and the width would just be x. SO your equation would be 4*4x*x=6400 ft^3. Then foil it out to get 16x^2=6400, then square root 6400 which will give you80, then divide by 16 so x=5 feet^3. That is your width but you length is 4 times that amount. So for length just do 4(5)=20 feet^3
Answer:
0
Step-by-step explanation:
-2 * -2 = 4
4 * 2 = 8
4 * -2 = -8 + 16 = 8
8-8 = 0
First, Make 2 equations to show each company in which "x" equals the number of days:
Andy's Rental Car = 20 + (30x)
Buddy's Rental Car = 36 + (28x)
Set it up like this:
20 + (30x) = 36 + (28x)
Now, solve for x by simplifying both sides of the equation and then isolating the variable.
x = 8
8 Days
