WILL GIVE BRAINLIST!!!!!!!FACTOR THIS COMPLETELY 4x^2 − 25

Mathematics
1 answer:
Wittaler [7]3 years ago
3 0

Answer:

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

Step-by-step explanation:

4x^2 is a perfect square with a square root of 2x, and 25 is also a perfect square with a square root of 5. The difference of two perfect squares a and b can be written as (\sqrt{a} - \sqrt{b} )(\sqrt{a} +\sqrt{b} ). So, 4x^2 - 25 can be factored into (2x-5)(2x+5).

Hope that helped! ;)

A machine paints 34o toy boats im 3/4 of an hour how many boats can he make per hour
leonid [27]
Here, we can set up a proportion:

34 ÷ 3/4 = ? ÷ 1
34*1 = 34
34÷3/4 = the time needed to build one toyboat

34/3/4 = 45.3333333333

45.3 repeating is not a whole number, so we need to approximate. 

45 is the closest whole number, 

So.. a machine can paint 45 toy boats per hour. 

I really hope that helped! :)

How would I solve this equation by showing my worki on each side?<br> X divided by 10= 7
Sav [38]

Answer:

x=70

Step-by-step explanation:

x/10=7

First you need to get the x by itself, so you should do the opposite of what is happening to the x.

In this case the x is being divided so you would need to multiply.

So multiply the x by 10 and this gets it by itself.

But you have to do to one side what you do to the other.

So multiply the other side by 10 as well!

This equals x=70

To show work on both sides, show the multiplication of both sides by 10

Find the base of a parallelogram with a slant height of 7cm and an perimeter of 63 cm2
vlada-n [284]

Base of parallelogram b = 24.5 cm

Step-by-step explanation:

We are given:

Perimeter =P= 63 cm^2

Slant Height =a= 7 cm

Base of Parallelogram =b= ?

The formula used is:

Perimeter = 2(a+b)

where a is height and b is base

Putting values:

Perimeter = 2(a+b)\\63=2(7+b)\\63=14+2b\\2b=63-14\\2b=49\\b=\frac{49}{2}\\b=24.5

So, Base of parallelogram b = 24.5 cm
