Factor 2a2 + 2b2 - 5ab

Mathematics

bekas [8.4K]3 years ago

Answer:

Using the relationship (x -y)^2 = x^2 + y^2 - 2x*y

We can assume that we have:

2a^2 = x^2

This means that x= √2*a

we also can assume tbat Y = √2*b

then we would have something like:

(√2*a - √2*a)^2 = 2a^2 + 2b^2 - 4ab

Where i see that in the written question there is a 5ab instead of a 4ab, but i guess this may be a typo

What is the solution of the following system?
Yakvenalex [24]
<h3>Answer:  B) no solutions</h3>

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

Explanation:

Let's isolate the variable y in the first equation

-2x - y = 1

-2x = 1 + y

1+y = -2x

y = -2x-1

Then we'll plug this into the second equation

-4x - 2y = -1

-4x - 2(-2x-1) = -1

-4x + 4x + 2 = -1

0x + 2 = -1

0 + 2 = -1

2 = -1

We run into a contradiction. No matter what x value we pick, the last equation will never be true. This leads to a domino effect to cause the first set of original equations to never be true when considered as a system.

Therefore, this system is inconsistent. There are no solutions. These two lines graph out parallel lines that never intersect.

What two numbers have 2,3,5 as factors
lukranit [14]
Two numbers with factors 2,3,5 are 30 and 60.
when we multiply 2 x 3 x 5 = 30
we get answer 30 and then again multiply with the number that is greater than 1 is 2 and then we get 2 x 2 x 3 x 5 = 60
So the first two numbers with factors 2, 3 and 5 are 30 and 60.

The formula for the volume of a cylinder = πr²h

r = Radius = 4 inches

h = Height = 5 inches

Volume of a Cylinder = π × 4² × 5

= 251.32741 cubic inches

Approximately , the Volume of the cylinder = 251.33 cubic inches.
