Answer:

5( 4x-5)(4x+5)

Step-by-step explanation:

80x^2 – 125

Factor out a 5

5( 16 x^2 - 25)

Inside the parentheses is the difference of squares

5 ( (4x)^2 - 5^2)

We know the difference of squares is  (a^2 - b^2) = (a-b) (a+b)

5( 4x-5)(4x+5)

Let f(x) = 3x + x², find f(4).

F(4) is equivalent to 28 because when you plug in 4 for the x, you get 28.

Determine if (3,-4) is a solution to y < 2x – 5.
spin [16.1K]
You would plug in the ordered pair into the equation.

1. Put the y value from the ordered pair in the y spot, and the x value in the x spot.

2. add up the x side

Does it equal the y side?

Im a bit confused as the question says “&lt” at least on my end? I’m not sure if that’s just the way it ended up being written or if it means something. Sorry if my answer doesn’t apply :(. But if it does, I hope it helps!
