Answer:

P = 4(2x + 5)

P = (2x + 5)+(2x + 5)+(2x + 5)+(2x + 5)

Step-by-step explanation:

Given that:

Perimeter of square = 4 * s

Where s = side length

If perimeter, P = 8x + 20

Then,

4s = 8x + 20

Divide both sides by 4

4s / 4 = (8x + 20) / 4

s = 2x + 5

P = 4s

P = 4(2x + 5)

Or

P = 2x + 5 in 4 places

P = (2x + 5)+(2x + 5)+(2x + 5)+(2x + 5)

Korvikt [17]

Answer:


Step-by-step explanation:

Bill + 220

Total is 538 so subtract 220 which gives you 318.

318/2 = 159

159+220 for Bill = 379

Bob has 159

Add 159 + 220 for Bill and 159 for bob = 538

So Bill has 379

and Bob has 159

What parent function has the following applications: profit, gravity, and calculating area?
Ronch [10]

Answer:

Suppose that you have a square of side length x, the area of this square will be:

A = x^2.

Now, by dynamics, we know that the position of an object that is falling down from a height H, can be written as:

H(t) = (-g/2)*t^2 + H.

We can see a pattern, x^2 is used in both.

Now, profit can be also modeled with quadratic equations, where our objective is to find the maximum of the quadratic (so we can have the maximum profit)

Then the parent function that is useful for gravity, calculating area and profit is the quadratic function:

f(x) = x^2

pedro has 6 packs of gum with p pieces in each pack he had a total of 72 pieces of gum decide whether each equation represents t
Serga [27]

Answer:

6p = 72 --- The equation

The solution is 12 packs i.e. p = 12

Step-by-step explanation:

No options given. So, I will solve generally.

Given

Packs = 6

Quantity = p per pack

Total = 72

Required

Determine the equation

This is calculated using:

Packs * Quantity = Total

6 * p = 72

6p = 72

Divide both sides by 6

p = 12

(25 points) A construction crew is lengthening a road. Let y represent the total length of the road (in miles). Let x represent
Tresset [83]

Answer:

L=193

Step-by-step explanation:

Initial length of the road =57mi

L= Total length

D=number of days worked

Number of miles added in 1 day= 4mi

Therefore,

L=57+D*4

After 34 days,

L=57+(34*4)

L=193mi
