Answer:

see explanation

Step-by-step explanation:

(a + b + c)² = (a + b + c)(a + b + c)

Each term in the second factor is multiplied by each term in the firs factor, that is

a(a + b + c) + b(a + b + c) + c(a + b + c) ← distribute all 3 parenthesis

= a² + ab + ac + ab + b² + bc + ac + bc + c² ←  collect like terms

= a² + b² + c² + 2ab + 2bc + 2ac

salantis [7]
E, because he is stealing everything, meaning he has a net profit. So, you would add everything. Since he 280 $1 bills, he just stole $280 which is a definite quantity, so we don't need a variable for it. Since everything else are indefinite quantities, we need variables (x, y, z). But, yeah, E should be the answer.

For the function g(x) = x – 2x^2, find g (–3) + 13
svp [43]

Answer:

<h2>g( - 3) + 13 = - 2</h2>

Step-by-step explanation:

g(x) = x - 2x²

To find g( - 3) + 13 substitute the value of x that's - 3 into g(x) and add 13 to it

We have

g( - 3) + 13 = - 3 - 2(-3)² + 13

= -- 3 - 2(9) + 13

= 3 - 18 + 13

We have the final answer as

<h3>g( - 3) + 13 = - 2</h3>

Hope this helps you
