HELP!! Given f(x)=5x squared and g(x) = x squared + 2x squared - 5x, what is F (x) * g(x)?

TEA [102]

X^2+2x^2-5x

((x^2)+2x^2)-5x

Pull the factors out

3x^2-5x=x(3x-5)

x(3x-5)

x(3x-5)*5x^2

5x(3x-5)*x^2

Final

5x^3*(3x-5)

Show the work for answer, if the area of a pizza is 153.94 square inches, find the length of its diameter

TEA [102]

Answer:

14 inch

Step-by-step explanation:

A = πr^2

153.94 = π * r^2

153.94/π = 49.001 = r^2

√49.001 = r = 7

radius * 2 = diameter

7 * 2 = 14 inch diameter

2√72 + 5√242 what is the answer for this question please can u tell me the right answer

Radda [10]

Answer:

67 $\sqrt{2}$

Step-by-step explanation:

Assuming you require to simplify the expression.

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

Simplifying the radicals

$\sqrt{72}$ = $\sqrt{36(2)}$ = $\sqrt{36}$ × $\sqrt{2}$ = 6 $\sqrt{2}$

$\sqrt{242}$ = $\sqrt{121(2)}$ = $\sqrt{121}$ × $\sqrt{2}$ = 11 $\sqrt{2}$

Then

2 $\sqrt{72}$ + 5 $\sqrt{242}$

= 2(6 $\sqrt{2}$ ) + 5(11 $\sqrt{2}$ )

= 12 $\sqrt{2}$ + 55 $\sqrt{2}$

= 67 $\sqrt{2}$
