Square with sides measuring 12 in. What is the perimeter and area?

2 answers:

48 is the perimeter, all sides in a square are equal, you take 12 * 4 which gives you 48.

For the area, you take two sides, length and width, and you multiply them, 12 * 12, this gives you 144.

Well a square has 2 dimensions (used for area) and 4 sides (used for perimeter). Perimeter is the measure of the total outside length of a shape, and since there are 4 sides on a square and each side of the square is 12 inches long, the perimeter can be found by multiplying the length of each side by the number of sides (12 x 4 = 48).
P = 48 inches
Area is the measure of the square units taken up by the shapes interior, so you multiply the lengths of the two dimensions in a square by each other to find the area (12 x 12 =144).
A = 144 inches^2

A pair of equations is shown below:

Archy [21]

Slope Intercept Form - y = mx + b

First you need the slope or m which in the first equation is 6 and in the second is 5

Next the y-intercept or b which in the first equation is -4 and in the second is -3

Here is an image of both equation plotted on a graph where the first equation is purple and the second is green

Hope this helps, if you need anything else i will edit it in :)

edit: The to lines intercept at the point (1,2)

Sorry, i wasn't completely sure what you needed i haven't done this in a while. If you still need more, I'll try to help.

If x=5, evaluate x^5 * x^-3

Artyom0805 [142]

Answer: 25

Step-by-step explanation:

Plug in x to the expression.

$5^5 * 5^{-3}\\$

When there is the same base of exponents is being multiplied the exponents add together and the base stays the same.

So this simplifies to, $5^2$ .

This then solves to 25.

i need with this math problem. I am confused on how to do it. If you could help me it would be great. There are 2 parts to this

Novay_Z [31]

She took a total of 60 minutes
she answered both mulitiple choice and extended response in the total time which is 60 minutes
she took 2 minutes on rach multiple choice question and 6 minutes for the extended response
let x=number of multiple choice questions
let y=number of extended response questions
we can deduce that
total time =x*2+y*6
60=2x+6y
also we can deduce
20=x+y
since 20 ia the sum of multiple choice and extended response
for part 2 we just solve the system of equations
60=2x+6y
20=x +y
lets multiply the second equation by 2 so we can get rid of x
60=2x+6y
40=2x+2y
subtracting the two equations from each other to yields
20=0 +4y
y=5
to get x we substitute in one of the equations we derived from question 1
x+y=20
substituting y for its value we get
x+5=20
x=15
