Answer:

Area: 5x + 10

Perimeter: 2x + 14

Step-by-step explanation:

Area = length times width

Perimeter = length (2) + width (2)

Multiply the length be the width. That gives you 5 (x + 2).

Then use the distributive property to simplify this expression. That gives you 5x + 10.

<u>Perimeter:</u>

Multiply the width by 2. That gives you 10.

Multiply the length by 2. That gives you 2x + 4

Add the 2 together. That gives you 10 + 2x + 4.

Combine all like terms. That gives you 2x + 14.

The U.S. annual energy consumption is roughly 1 x 1020 joules per a year. If there are 350,000,000 people in the U.S., express t

AnnZ [28]

Answer with Step-by-step explanation:

Given the total energy consumption for all of the population is

$E=1\times 10^{20}Joules$

Thus energy consumed by each person per year can be obtained by dividing the total energy consumed by the total population Thus we get

$E_{per\cdot person}=\frac{1\times 10^{20}}{350\times 10^{6}}\\\\E_{per\cdot person}=28.57\times 10^{10}Joules/Year$

Now the energy consumed in each second assuming that there are 365 days in each year equals

$E_{second}=\frac{28.57\times 10^{10}}{365\times 24\times 3600}\\\\E_{second}=9059.49Joules$

How do you graph equations

Sav [38]

Yes, so start by solving for y by subtracting everything else to the opposite side of the = from y.

1. y = 5 - x
2. y = x - 1

Now that we have our two equations in point-slope form, we can create graphs.

Our point-slope form is y = mx + b where m = slope of line and b = y-intercept.

The slope of equation 1. is -1 and the slope of equation 2. is 1

The y-intercept (how much the line goes up or down on the y-axis) for equation 1. is 5 and the y-intercept of equation 2. is -1

Two numbers are missing from this table. How can the missing numbers be

KiRa [710]

Answer:

multiply input number by 4

Step-by-step explanation:

In the figure attached, the problem is shown.

We can see the following values:

input = 1, output = 4*1 = 4

input = 4, output = 4*4 = 16

input = 7, output = 4*7 = 28

Then, the missing numbers can be found multiply input number by 4
