20 × .5 = 10
20 × 1 = 20
60 - 10 = 50 - 20 = 30
30 ÷ 2 = 15
20 + 20 + 15 = 55

Simplifty (x - 4)(x +8)

Answer: x² + 4x - 32

Step-by-step explanation: So to multiply these two binomials together, let's use the F.O.I.L. method.

Remember, F.O.I.L. stands for First, Outter, Inner, Last.

This is because we start with the product of the first terms which is x², then we add the product of the outer terms which is 8x, then we add the middle terms which is -4x, and then we add the product of the last terms which is -32.

So we have x² + 8x + -4x + -32.

Combining the like terms 8x + -4x, our final answer is x² + 4x - 32.

Determine whether the ordered pair is a solution of the linear equation y = 11r - 4 (0 -4)

KiRa [710]

Hi there!

»»————-　★　————-««

I believe your answer is:

Yes, it is a solution.

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

I am assuming that 'r' is supposed to be 'x'.

⸻⸻⸻⸻

$y=11r-4\\------------\\\rightarrow -4 = 11(0) - 4\\\\\rightarrow -4 = 0 -4\\\\\rightarrow \boxed{-4=-4}$

⸻⸻⸻⸻

The ordered pair is a solution. You can also tell that it is a solution because the equation given is in slope-intercept form, and '-4' is in b's spot.

⸻⸻⸻⸻

$y = mx+b$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.
