What is the area of a square whose perimeter is 12?

Answers

We know that a square has an equal height and width. So if all 4 sides, which are equal in length, add up to 12, then we can find the length of one side by dividing 12 by 4:
12/4= 3

If the length of one side is 3, we can multiply the height (3) by the width (3) to find the area.
3*3= 9

Answer: the area of the square is 9.

P=4L
12=4L
3=L

A=L^2
A=3^2
A=9

What is the gcf of 48y and 36xy

Answers

Answer:

GCF = 12y

Step-by-step explanation:

We have to find the GCF of 48y and 36xy

For finding the GCF, we find the factors of these two expression.

The factors are

$48y=2*2*2*3* y$

$36xy=2*2*3*3* x* y$

Now, we see the common terms in these two. That will be the GCF.

GCF = common terms in these two factors.

We can see that $2*2*3* y=12y$ is common.

Hence, GCF = 12y

48y and 36xy....the GCF would be 12y...because the highest number that goes into both 36 and 48 is 12. And the only variable that appears in both expressions is y.

How many solutions are there for 6x+35+9x=15(x+4)-25

Answers

Answer: The given equation has an infinite number of solutions.

Step-by-step explanation: We are given to find the number of solutions for the following linear equation :

$6x+35+9x=15(x+4)-25~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

To find the number of solutions, we must try to solve the given equation.

The solution of equation (i) is as follows :

$6x+35+9x=15(x+4)-25\n\n\Rightarrow 15x+35=15x+60-25\n\n\Rightarrow 15x+35=15x+35\n\n\Rightarrow 15x-15x=35-35\n\n\Rightarrow 0=0,$

which is always TRUE.

Thus, the given equation has an infinite number of solutions.

there is infinite many solutions for this answer.

Which measure is of an angle that is coterminal with a 95 degree angle

Answers

1). You haven't told us what your choices are, so there's no way
we can help you choose the correct one.

2). An angle that is to be coterminal with another angle of 95 degrees
doesn't need to be any particular size. It just needs to use the same vertex
that the 95-degree one uses.
