5 0

Answer:

25 K³ - 35k²+ 50 K - 40

===========================================

Step-by-step explanation:

Given that :

(-5k + 5)(-5k² + 2k - 8)

= -5K (-5k² + 2k - 8) + 5 (-5k² + 2k - 8)

= 25 K³ - 10k² + 40 K - 25 K² + 10 K - 40

= 25 K³ - 35k²+ 50 K - 40

<u>So, the product = 25 K³ - 35k²+ 50 K - 40</u>

What is the slope–intercept form of the equation 4x − 2y = 9?
adelina 88 [10]
Hey there! :D

Slope intercept form: y=mx+b

4x-2y=9

Add 2y to the other side. 

4x=9+2y

Subtract 9 on both sides.

4x-9=2y

Flip the equation over. 

2y=4x-9 <== slope intercept form 

I hope this helps!

A bag contains 25 balls 20 of which are blue what percentage of balls are not blue
Artist 52 [7]

Answer:

20%

Step-by-step explanation:

20/25 = blue

This means 5/25 of the balls in the bag are NOT blue

(25-20 = 5)

We need to convert 5/25 to a percentage

\dfrac{5}{25} = \dfrac{5\times4}{25\times4}=\dfrac{20}{100}

% = per cent

"per" means "out of"

"cent" means "one hundred"

so

20/100 = 20%
