Answer:
5(3x + 5) or 15x + 25
Step-by-step explanation:
A regular pentagon has 5 sides of equal length. The perimeter is the sum of the lengths of those sides. We can use multiplication to find the sum of 5 of the same value:
P = 5(3x +5)
Perhaps you want it expanded. Using the distributive property, we multiply each term in parentheses by 5:
P = 15x + 25
The first part of the answer can be found by finding the GCF between 15 and 25. 15 is divisible by 1, 3, 5, and 15. 25 is divisible by 1, 5, and 25. You can see that their GCF is 5. Next, you need to look at the variables. The first monomial has a, b, and
. The second monomial has
, b, and c. They each have at least one a, one b, and one c, so those will be in the GCF (abc). If you put that together with the 5, you get that the GCF is
5abc.
Answer: Choice B) 17.5 feet
A = Area of rectangle
L = length
W = width
The formula to use is A = L*W, so we multiply length and width.
We know W = 7 but we don't know what L is.
We know that A = 122.5 is also given
So let's solve for L
A = L*W
L*W = A
L*7 = 122.5 plug in the given values
7*L = 122.5
7*L/7 = 122.5/7 divide both sides by 7
L = 17.5
He should cut 17.5 feet of streamer. Keep in mind that this only applies if Adrian wants to make the streamer completely taut and a straight line across the ceiling/wall. If he wants the streamer to hang down a bit (forming a shape like a rope bridge in a sense), then the streamer's length will have to be a bit longer to account for the extra distance along the curve.
