Answer:

The number is 3

Step-by-step explanation:

Ok, first thing's first: we need to make the words into an actual equation.

since it just says a number I'll use x

3 times x + 4 = 13

3x +4 =13

Now that we have our equation, we can solve for x

3x + 4 = 13

     -4      -4

3x = 9

I subtracted 4 on both sides to get rid of the 4 and move it to the other side of the equation, so we can try to get x by itself.

3x =9

/3     /3

x = 3

I divided both sides by 3 to get rid of the 3 that's being multiplied by x

Now we have our number : x = 3

I hope this helps :)

solong [7]

Answer: 442

Step-by-step explanation:

f(x)=2x^3+5\sqrt{(x-2)}

f(6)

Simply replace all the x's in the equation for 6

f(6)=2(6)^3+5\sqrt{(6-2)}\\ f(6)=2(216)+5\sqrt{4}\\ f(6)=432+5*2\\f(6)=432+10\\f(6)=442
