Its a square, so all the sides are equal. Also, since the area of a square (rectangles) is equal to the height times the length, which are both the same, the area of the square is equal to x², where x is the length of any one side of the square, x²=256. now you square root both sides of that equation, x=√256, and the square root of 256 is 16. 

Tl;Dr: each side is 16 feet long.

Evaluate piecewise functions
Vika [28.1K]

Answer:

F(4) = 9

Step-by-step explanation:

Notice that for f(4), we need to use the function definition for the partitioned Domain that includes x = 4, and that is the expression :

f(x) = x^2-7

Therefore:

f(4) = 4^2-7 = 16-7 =9

Writing lan's car can go 217 miles on 7 gallons of gas. During a drive last weekend, lan used
jolli1 [7]

Answer: Ian would have drove 91 miles using only 3 gallons of gas.

Step-by-step explanation: I used paper and pencil and used a T-chart putting one section at the top “gallons” and the other “miles”; under gallons I put 7 because the question stated with “7 gallons of gas”; under miles I put 217 because the question states that with 7 gallons of gas Ian’s car travels 217 miles so using the T-chart I want to simply the 7 gallons of gas to one gallon of gas to figure out how miles Ian’s car would go only using 3 gallons of gas; by dividing 7 by 7 giving me 1, and with a T-chart you wanna do the same thing to both sides meaning I divided 217 by 7 as well giving me 31 for 1 gallon of gas, meaning Ian’s car would travel 31 miles with only using 1 gallon of gas. After I find that answer I go to multiply the 1 under “gallons” by 3 to and again, if you do it to one side you have to do it to the other meaning I multiplied 31 my 3 as well; giving me 91. Meaning with only using 3 gallons of gas Ian’s car would travel 91 miles!

The perimeter of a rectangular playground can be no greater than 120 meters. The width of the playground cannot exceed 22 meters
Maslowich

Answer:

There are an infinite number of values satisfying the requirements; every couple of numbers satisfying the following conditions are valid:

base = 60-w meters

width = w meters

0 < w <= 22

Step-by-step explanation:

Since the playground has a rectangular shape, let us us call b the base of the rectangle and w its width. In order for the rectangle to satisfy the condition of  P = 120, we need for the following equation to satisfy:

2b + 2w = 120

Solving for b, we get that b = (120 - 2w)/2 = 60 - w .

Given a particular value (w) for the width, the base has to be: (60-w).

Therefore, the possible lengths of the playground are (60-w, w), where 60-w corresponds to the base of the rectangle and w to its width. And w can take any real value from 0 to 22.
