Factor (difference of squares) the binomial 25x^2-4 and find one of its factors
Lunna [17]

Step-by-step explanation:

Hey, there!

Here,

Given that:

= 25 {x}^{2}  - 4

we need to find factor,

As it is in a^2-b^2 form as per its factor (a+b) (a-b), keeping same formula here,

25x^2 means (5x)^2

and 4 means 2^2

Now, it would be,

= ( {5x)}^{2}  -  {2}^{2}

= (5x + 2)(5x - 2)

Therefore, it's factor would be (5x+2)(5x-2).

2 bags = 4 feeders
You need 40 feeders.
40 feeders (need to fill up) ÷ 4 (feeders per 2 bags) = 10
10 x 2 (bags) =
20 bags for 40 feeders

Find the distance between (-6, -12) and (4,8) using the distance formula.
Romashka [77]

Answer:

The distance formula is 22.360679775

if you round it to the nearest tenth, then the answer is 22.4

Step-by-step explanation:

(-6, -12) and (4,8)

<u>(x2 - x1)² + (y2 - y1)²</u>

Place the x and y values

(4 - - 6)² + (8 - - 12)²

= 10² + 20²

= 100 + 400 = 500

√500 = 22.360679775

Round it to the nearest tenth, and you will get 22.4

Hope this helps!
