Answer:
P=88. L=3w
P= 2(w)+2(L)
Then substitute the values into the equation
88=2w+2(3w)
Then solve for w and its length which is 3w
Answer:
I'm pretty sure it is 0.75
Step-by-step explanation:
It is a3 so that means it is the 3rd answer in the sequence.
Number is an isosceles triangle number seven is a right angle triangle number 9 I believe is a scalene triangle number 10 is a right angle triangle I also believe 11 is a scalene triangle and I believe number 8 is equilateral triangle
Take into account, that in general, a cosine function of amplitude A, period T and vertical translation b, can be written as follow:

In the given case, you have:
A = 4
T = 3π/4
b = -3
By replacing you obtain:

Hence, the answer is:
f(x) = 4cos(8/3 x) - 3
Yes you do.
The shelf is 24 in. long, so to fit, the total width of all the cases must be < 24 in.
If each case is 3/8 inches:
60 * 3/8 = 22.5
22.5 < 24, therefore they will all fit.
