Answers

Answer:

n = 1x = 65

Step-by-step explanation:

Given

18n + 12 = 27n + 3 5(x + 7) = 6(x - 5)

Solving for variables

18n + 12 = 27n + 3 18n - 27n = 3 - 12-9n = -9n = -9/-9n = 1

Henry is planning to create two rectangular gardens.

Which function, f(x), can Henry use to determine the area, in square feet, of the first garden?
a f(x) = 48x
O f(x) = 48 - X
f(x) = 48 – x2
d -
f(x) = 48x-x²

Answers

Answer:I’m taking the same quiz rn and am confused

Step-by-step explanation:

The function to represent the area of the garden is f(x) = 48x-x²

What is a function?

A function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and range.

Given that, Henry has 96 feet of fencing to enclose the first rectangular garden. The garden will be x feet wide.

Perimeter = 96 feet

Therefore,

2(l+x) = 96

l+x = 48

l = 48-x

Area = lXw

= x(48-x)

= 48x-x²

Hence, The function to represent the area of the garden is f(x) = 48x-x²
