Answer:

Step-by-step explanation:

Perimeter is all sides added together.

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

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

Answer:

x-2=x x=0

No Solution

x+1=1-x

Cancel 1 on both sides

Subtract −x from both sides

x+x=0

Simplify x +x to 2x

2x=0

x=0

Check Answer

x+1=1-x

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
