Answer:
27
Step-by-step explanation
Sally = 4 x 3 = 12(left) + 15(spent) = 27
Lucy = 24(spent) + 3(left) = 27 (we dont multiply this part bc Lucy spent 9 more dollars than Sally, 3 x 3 is 9 which equals the difference)
The area of a square increases by a factor 2n when its perimeter increases by a factor of n
<h3>How to determine the perimeter and area of each square?</h3>
Start by calculating the side length of each square
From the diagram, we have the following side lengths in ascending order
Square 1 = 2
Square 2 = 4
Square 3 = 8
<u>The perimeter</u>
This is calculated as:
P = 4 * Side length
So, we have:
Perimeter Square 1 = 4 * 2 = 8
Perimeter Square 2 = 4 * 4 = 16
Perimeter Square 3 = 4 * 8 = 32
Hence, the perimeters of the squares are 8, 16 and 32
<u>The area</u>
This is calculated as:
A = Side length^2
So, we have:
Area Square 1 = 2^2 = 4
Area Square 2 = 4^2 = 16
Area Square 3 = 8^2 = 64
Hence, the areas of the squares are 4, 16 and 64
<h3>What happens to the area of a square when its perimeter increases by a factor of n?</h3>
Using the computations in (a), the area of a square increases by a factor 2n when its perimeter increases by a factor of n

Answer:
a non negative number
Step-by-step explanation:
1: a nonnegative number equal in numerical value to a given real number
2: the positive square root of the sum of the squares of the real and imaginary parts of a complex number
Answer:
1) It has a y-intercept of 4
2) A, the rate of change represents how fast the boys run every hour.
Answer:
It is the third answer.
Step-by-step explanation:
It is the third answer because when you look at the equation it is 5x is greater then negative 5 so that means it’s the 3rd answer hope this helped!
