A is always the number with a variable and is squared

B is always the one with a single variable

C is always the lone number or constant

Thus, here are the correct answers:

A = 3x^2
B = -2x
C = 5

Hope this helps!

The volume of this sphere is 972pi cubic inches. What is its radius?
maria [59]
4/3pi *r3 = 972pi
Divide both side by pi

4/3 *r3 = 972

r3 = 972* 3/4

r3 = 729

r = the square root of 729 to the third power (I don't know if I'm expressing this correctly but answer is 9, hope you get that)

r = 9 that's your answer.

Hope it's correct, appreciate if you could let me know

Help please I'm stuck show and explain your work
Deffense [45]

The expressions D, E, and F represent a correct solution to the equation.

Step-by-step explanation:

Step 1:

First, we need to solve the given equation and find the value of x which satisfies the equation.

6(x+4)=20, (x+4) = \frac{20}{6}   = 3.333,

x = 3.333 - 4 = -0.666.

So the value of x for the given equation is -0.666.

Step 2:

Now we evaluate the values of the six given options to see which ones have an x value of -0.666.

A. \frac{20-4}{6}= \frac{16}{6}  = 2.666,

B. \frac{1}{6} (20-4)= \frac{1}{6} (16)=\frac{16}{6} = 2.666,

C. 20 -6 -4 = 20 - 10 = 10.

D. \frac{20}{6} -4= 3.333 - 4 = -0.666,

E. \frac{1}{6} (20-24) = \frac{1}{6} (-4)= -0.666,

F. (20-24)\frac{1}{6} = (-4)\frac{1}{6} = -0.666.

So the options D, E, and F represent a correct solution to the given equation.

Pens are on sale for 3 pens for $6 Karen bought 3 pens Leo bought 1 pen how much more did Karen spend than Leo
Rasek [7]
If the correlation is correct, then 1 pen would be equal to $2. In this case, karen spent $2 for each pen for a total of 3 pens for $6. If Leo bought 1 pen, he would spend $2. So, $6-$2=$4. Karen spent 4 more dollars than Leo. If this helped, please mark me brainliest, thank you and if you need more help, feel free to message me!
