Answer:

Answer:

x + 3

Step-by-step explanation:

when you factor the expression, the answer is 3x(x+3)^2

What does "Classify the polynomial by the number of terms" mean

Answers

"Classify the polynomial by the number of terms" means a term contains both the variables and its coefficient. For example a "monomial" has one term like 2x^(2).

A binomial has 2 terms like 3x^(2)+6x

A trinomial has 3 terms like 4x^(2)+5x-8

And a polynomial has 4 or more terms.

So basically one can classify the type of polynomial by counting the number of terms in a given equation.

If annual college tuition and fees cost $8675, room and board cost $2235, books are $1850, and other charges are $250 per year, what is the total cost for 1 year of attendance?

so the answer is $13,010
13010 because all you need to do is add all of the numbers up

Solve 4^2x=7 by graphing

Answers

Answer:

0.702 is the solution of this function.

Step-by-step explanation:

We have

           4^(2x)=7\n\n4^(2x)-7=0

Let us plot y=4^(2x)-7 when y value of this function is zero then that is the solution of 4^(2x)=7

Refer the figure given, we have at x = 0.702 y value is zero that is 0.702 is the solution of this function.

         
I can't solve that by graphing but I'll try logarithms:
log(7)4 = 2x
log(7)/log(4) = 2x
1.403 = 2x
x = 0.702

Evaluate the expression when c=6 and y=7. 2y-c

Answers

Hey there!


2y - c

= 2(7) - 6

= 14 - 6

= 8


Therefore, your answer is: 8


Good luck on your assignment & enjoy your day!

Answer:

= > 2y - c

= > 2(7) - 6

= > 14 - 6

= > 8
