Answer:

Step-by-step explanation:

90 times 3 = 270

9x-3 + 6x + 48 = 270

add like terms, 48-3 = 45

9x + 6x + 45 = 270

subtract 45 both sides and add like terms again

15x = 225

divide 15 on both sides

x = 15

G(n) = 4n+5 f(n)= n^3+3n^2 find (g+f)(n)

Tpy6a [65]

Given:

The two functions are:

$g(n)=4n+5$

$f(n)=n^3+3n^2$

To find:

The function $(f+g)(n)$ .

Solution:

We have,

$g(n)=4n+5$

$f(n)=n^3+3n^2$

Now,

$(f+g)(n)=f(n)+g(n)$

$(f+g)(n)=n^3+3n^2+4n+5$

Therefore, the correct option is B.

HELP PLEASE!!!!!!!!!!!!!!!!!!!!!

Answer:

Considerations:

$$y=-(x) \left \{ {{\text{if } x0} \atop {{\text{if } x> 0\text{ then }y$

$y=x\left \{ {{\text{if } x0}} \right.$

Also,

$-\frac{a}{b}=\frac{-a}{b}=\frac{a}{-b}, b\neq0$

A positive number divided by a positive number results in a positive quotient, and its opposite is always negative.

The fraction $\frac{5}{-12}$ can be described as a positive number divided by a negative number, which always result in a negative quotient.

The fractions have same value, so Liam is correct.
