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 .
Answer:D
Step-by-step explanation:
Answer:
The correct answer is A. 5(x + 3)(x - 3)
Step-by-step explanation:
In order to solve this, we start by pulling out the greatest common factor.
5x^2 - 45
5(x^2 - 9)
Now we can use the difference of two squares to factor the rest of the equation.
5(x + 3)(x - 3)
We have that
<span>2x + y = 4
to graph this equation </span><span>we will look for the x and y intercepts
step 1
find the x intercepts
y=0
2x+0=4-----> x=4/2-----> x=2
the point is (2,0)
step 2
</span>find the y intercepts
x=0
0+y=4-----> y=4
the point is (0,4)
step 3
with the two points graph the line
see the attached figure

Answer: 4 large bottles of water for $3.
Step-by-step explanation: To find how many large water bottles you can buy with $3, you’ll have to divide 12 by 3 which equals to 4. You can check your answer by multiplying 4 x 3 which equals to 12, which is the original amount of large water bottles you can buy for $9.
