Answer:

It is because you have to get rid of the power of 2 from c. In order to get rid, you have to square root it on both sides :

c² = 74

√(c²) = √74

c^(1/2×2) = √74

c = √74

Using Indices formula, (a^m)^n = a^(mn)

25 pts to who ever can help with this question:
pentagon [3]

Answer:

A. 5s+2

B. 8s+8

C. 75

D. 27

Step-by-step explanation:

Is difficult to read the exact expressions. If a mistake is present then fix the number and use the same method.

A. The perimeter of the square is all 4 equal sides added together. The length of a side is \frac{5s+2}{4}. Since there are four sides then:

P= \frac{5s+2}{4}+\frac{5s+2}{4}+\frac{5s+2}{4}+\frac{5s+2}{4} = 5s+2

Adding 1/4+1/4+1/4+1/4=1. This applies here leaving 5s+2 as the answer.

B. The perimeter of the rectangle is all four sides added together. A rectangle has two pairs of equal side so P = 2l+2w.

P = 2(s+9) + 2(3s-5)\\P = 2s+18 +6s-10\\P=8s+8

C. If s=5 then the sum of the two perimeters is:

5s+2+8s+8

5(5)+2+8(5)+8

25+2+40+8

75

D. Subtract the two perimeters by computing s=7:

8s+8 -(5s+2)

8s+8-5s-2

8(7)+8-5(7)-2

56+8-35-2

64-35-2

29-2

27

I have another Brainliest
Lynna [10]

Answer:

  1. 5 times
  2. $22.75

Step-by-step explanation:

1.  Let n represent the number of times you can ride. To keep the cost within your budget, you must have ...

  2.75n ≤ 15.00

  n ≤ 5.45

You can ride 5 times. You don't have enough money to ride 6 times.

__

2. You can choose the correct answer using estimation of the costs. (You only need to work out the numbers in detail if an estimate doesn't get you close enough.)

3 all-day passes are a little more than $20 each, so cost a little more than $60.

2 rides on the Mountain Coaster are another $9, so your total cost will exceed $69. That means you will get less than $31 in change from $100. The only answer choice in that range is $22.75.

If you add up the costs of the passes and rides, you find they come to $77.25, so your change from $100 will be $22.75.
