Answer:
6(3) - 4 + (3)^2

Explanation:
We will do this on two steps:
1- get g(x)-f(x)
2- substitute with x = 3

Step 1:
f(x) = 4-x^2
g(x) 6x
g(x) - f(x) = 6x - (4 - x^2)
= 6x - 4 + x^2

Step 2:
Substitute with x = 3 as follows:
g(x) - f(x) at x = 3 is:
6(3) - 4 + (3)^2

Hope this helps :)

Answer:

(40+2b)cm

Step-by-step explanation:

Complete question

Jimmy is putting up a fence around his rectangular garden. One side of the garden is 20 feet long, and b represents the width, How much fencing material will he need.

To get the amount of fencing material needed, we will find the perimeter of the fence

perimeter of the fence = 2(L+W)

L is the length

W is the width

Given

Length = 20feet

Width = b feet

perimeter of the fence = 2(20+b)

perimeter of the fence = 2(20) + 2b

perimeter of the fence = 40+2b cm

Hence the amount of material needed will be (40+2b)cm

A) 85 acres with 1.02 x 10⁶ plants
b) 100 acres with 1.7 x 10⁷ plants
c) 110 acres with 1.9 x 10⁶ plants
d) 205 acres with 3.4 x 10⁵ plants

a) 1.02 x 10⁶ = 1,020,000 ÷ 85 acres = 12000 per acre
b) 1.7 x 10⁷ = 17,000,000 ÷ 100 acres = 170,000 per acre
c) 1.9 x 10⁶ = 1,900,000 ÷ 110 acres = 17,272.73 per acre
d) 3.4 x 10⁵ = 340,000 ÷ 205 acres = 1658.54 per acre

Among the choices, Letter C. 110 acres with 1.9 x 10⁶ plants has the density of approximately 17000 plants per acre. Its actual density is 17,272.73 plants per acre.
