If, g(x)=-2(x+2)-6 what is g(b-5)=
Misha Larkins [42]

The value of g(b-5)=-2b

<u>Solution:</u>

In the notation g(x) we know that whatever is put in the parentheses is what we replace for x. In the given situation, since it is g(b-5) we have to replace every x in the function with b-5. That is if,

g(x)=-2(x+2)-6

then, g(b-5)=-2((b-5)+2)-6

\Rightarrow g(b-5)=-2(b-5+2)-6

On solving we get,

\Rightarrow g(b-5)=-2(b-3)-6\rightarrow g(b-5)=-2b+6-6

\Rightarrow g(b-5)=-2b

Please help I’m confused math is hard!
Butoxors [25]

Answer:

Step-by-step explanation:

basically, what they are asking you is to factor and then plug in the values (x=3; x=4) that they gave you.

first, you need to factor out the equation.

start with the original equation.

V=4x^3+10x^2+4x

factored form:

V= 2x(2x^2+5x+2)

next, you're going to want to plug in the values.

the answer asks for x=4, but you should do both.

v=2(3)(2(3)^2+5(3)+2)

do not forget to do the exponents before!

v=6(18+15+2)

v=6(35)

v=210 ft^2

that's the answer for if x was equal to 3.

V= 2x(2x^2+5x+2)

<em>don't forget to write the original equation first. </em>

V=2(4)(2(4)^2+5(4)+2)

<em>V=8(36+20+2)</em>

<h2><u><em>V=464 ft^2  </em></u></h2>

⬆is your answer! hope this helped!!
