Answer:

Step-by-step explanation:

Perimeter is all sides added together.

l is length, w is width, and P is perimeter.

2l + 2w = P\\2(5x) + 2(x - 3) = 42\\10x + 2x - 6 = 42\\12x - 6 = 42\\12x = 48\\x = 4

After 4 days, a bookstore has 140 copies of a new title still on hand. After 9 days, the bookstore has 50 copies still on hand.
alexira [117]

Answer:

c(t) =-18t +212

Step-by-step explanation:

Given

(t_1,c_1) = (4,140)

(t_2,c_2) = (9,50)

Required

Determine the equation

First, we calculate the slope (m)

m = \frac{c_2 - c_1}{t_2 - t_1}

m = \frac{50 - 140}{9-4}

m = \frac{-90}{5}

m = -18

The equation is then calculated as:

c =m(t - t_1) + c_1

c =-18*(t - 4) + 140

c =-18t +72 + 140

c =-18t +212

Hence, the function is:

c(t) =-18t +212

PLEASE HELP!! Find the area of the figure to the nearest tenth. Show your work
UkoKoshka [18]
By the Pythagorean Theorem:

DE=√(100-64)

DE=√36

DE=6 ft

So our area is just a 4by4 square and a triangle with a height of 8 and a base of 6 so

A=(4*4)+(6*8)/2

A=16+24

A=40 ft^2
