Perimeter is used to find the total length. And its units are not in squares.

Areas are used to measure the number of unit squares needed to cover a flat surface. And its unit is in squares, for e.g. meter square, cm square etc .

So out of the two given options, area is used to measure the square units covered by the flat surface .

Divide p(x)=x^4+6x^3+7x^2-6x-8 by x+4. What is the remainder
postnew [5]

Use the remainder theorem; dividing a polynomial p(x) by x-c leaves a remainder equal to p(c). Here

p(x)=x^4+6x^3+7x^2-6x-8

\implies p(c)=(-4)^4+6(-4)^3+7(-4)^2-6(-4)-8=\boxed{0}

A group of friends were working on a student film that had a budget of $1140. They used 65% of their budget on costumes. How muc
Stells [14]

Answer:

They use 741 dollars

Step-by-step explanation:

Write 65% as

65/100

Since, finding the fraction of a number is same as multiplying the fraction with the number, we have

65/100 of 1140 = 65/100× 1140

Therefore, the answer is 741

If you are using a calculator, simply enter 65÷100×1140 which will give you 741 as the answer.

5x-(5x+3=-1/3(12x+21)​
katrin2010 [14]

Answer: x = -1

Step-by-step explanation:

i assume you mean

5x-(5x+3) = -1/3(12x+21)​

lets start with the left

-(5x+3) can be turnd into -5x-3

now it is

5x-5x-3 and that can be just -3

now lets go to the right and get rid of the 1/3

we see the 3 at the bottom of 1/3, and (12x+21)​ can be factored with 3

so 1/3 x 3(4x+7) is what we get

1/3 x 3 cancels out so we are left with

-3 = (-4x-7)

lets try to get -4x by itself

if you move -4x to the left, turning it into 4x, and move -3 to the right, turning it into 3, you get 4x = -7 +3

-7 +3 = -4

4x = -4

devide by 4

4x/4 = -4/4

x = -1
