Answer with A B C D. Correct answer gets brainlest.

C:

Step-by-step explanation:

Multiplying numbers together can be represented by exponents.

For instance, x*x*x can be represented as . The x is called the base, and the 3 is the exponent. The exponent represents how many of the base are multiplied.

In this case, you have 4*4*4*4*4*4. This can be represented by - there are six fours being multiplied, and four is your base.

answer:

c) the x-coordinate of the center of the circle increases by 3

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !
