In order to simplify an expression you have to have the same variables, to the same power.

1a) There are no more H's or numbers without a variable.

1b) The variables do not match.

1c) The variable is to a different power so it can't be simplified.

So to simplify you combine your "like terms"

2a,b, and c are correct :)

2d) already simplified

2e) since the variables are the same, just focus on the numbers (x=h since it won't let me use it) answer: 6x
10x - 4x \\ 10 - 4 = 6 \\ 6x
2g) For this one 9 has no variable and no like terms, so it stays by itself, just focus on the a's (x=a) answer: 9+4x
9 + 7x - 3x \\ 7 - 3 = 4 \\ 9 + 4x
2j) answer: 11y^2+5y
8y + 6y {}^{2}  - 3y + 5y {}^{2}  \\ 8y - 3y = 5y \\ 6y {}^{2}  { + 5y} {}^{2}  = 11y {}^{2}  \\ 11y {}^{2} + 5y

Answer:

520,000

Step-by-step explanation:

1400 x 200 = 280000

(400 + 800) x 400 /2 = 240000

240000 + 280000 = 520000

For what value of the domain {–3, –1, 0, 2, 5} does f(x) = g(x) When f(x) = 3x – 4 and g(x) = x2 – 2
zavuch27 [327]
F(x) = g(x)
3(2) - 4 = (2)² - 2
6 - 4 = 4 - 2
2 = 2
I just substituted all the values in the domain to see which one would work. That's not really the quickest way but that's the only way I know
