Answer:

Yes. x = 30 is a solution for 120 = 4x

Step-by-step explanation:

If x is 30 you substitute the X next to the four for 30 that means you multiply 30 x 4 and you get 120 so X does equal 30

What is the difference of the two polynomials? (9x2 + 8x) – (2x2 + 3x) A 7x2 + 5x B.7x2 + 11x C.11x2 + 5x D.11x2 + 11x

xxTIMURxx [149]

we have

$(9x^{2} + 8x)-(2x^{2} + 3x)$

Remove parentesis

$9x^{2} + 8x-2x^{2} -3x$

Combine like terms

$9x^{2} -2x^{2} + 8x -3x$

$7x^{2} + 5x$

therefore

the answer is

$7x^{2} + 5x$

Write a relationship for a function whose k(x) values are 5 more than four times the principal square root of x .

bearhunter [10]

Answer:

$k(x)=5+4\sqrt{x}$

Step-by-step explanation:

Write a function whose k(x) values are 5 more than four times the principal square root of x.

So,

the principal square root of x $=\sqrt{x};$

four times the principal square root of x $=4\sqrt{x};$

5 more than four times the principal square root of x $=5+4\sqrt{x};$

Thus,

$k(x)=5+4\sqrt{x}$
