Find the greatest common factor. 2y^3, 8y

Ira Lisetskai [31]

Answer:

STEP1:Equation at the end of step 1

2y3 - 8y

STEP2:

STEP3:Pulling out like terms

3.1 Pull out like factors :

2y3 - 8y = 2y • (y2 - 4)

Trying to factor as a Difference of Squares:

3.2 Factoring: y2 - 4

Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A2 - AB + BA - B2 =

A2 - AB + AB - B2 =

A2 - B2

Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : 4 is the square of 2

Check : y2 is the square of y1

Factorization is : (y + 2) • (y - 2)

Final result :

2y • (y + 2) • (y - 2)

Mind my hand writing but I’m not sure what sign to put the “-“ or the “+” ?

Ierofanga [76]

hello!

so the answer that you put there is actually wrong and i'll tell you why and how to do it

so since you are adding the two:

-8x + 9x = x (so you got this part right)

-12 + 4 = -8 (this is where you got it wrong, -12 added 4 goes up in value to -8)

so the final answer is x - 8

i hope this helped and have a nice day!

Triangle A has an area equal to one-third the area of Triangle B. Triangle A has an area of 3 1/2 square meters.

attashe74 [19]

Answers:

A. B 1/3 represents the area of triangle B

B. Triangle B area = 21/2 m² or 10 1/2 m² or 10.5 m²

Step-by-step explanation:

Ok, we have two triangles measured in square meters (m²)

∆ a = 1/3 b and ∆ b = 3 1/2

Since these two areas have something in common (symbol a) we can consider they are almost the same, so we put them like this:

∆ a => 1/3 b = 3 1/2 <= ∆ b

Now that we know we can move some values. first we are gonna multiply the mixed fraction (3 1/2) to make it a regular fraction. As 3 is a whole, we can also write it on the following way:

$\frac{3}{1} +\frac{1}{2}$

We add these fractions:

$\frac{3}{1} +\frac{1}{2} = \frac{(3x2)+(1x1)}{1x2} =\frac{6+1}{2} =\frac{7}{2}$

The equation with this part solved is:

$\frac{1}{3} b=\frac{7}{2}$

Since the 1/3 is multiplying, it goes to the other side dividing the number on the right:

 $b=(\frac{7}{2} )/(\frac{1}{3} )$ 

And then, we can solve the rest by inverting the second fraction ( $\frac{1}{3}$ ) and multiplying it by the first one:

 $b=\frac{7}{2} / \frac{1}{3} \\$ 

 $b=\frac{7}{2} x \frac{3}{1} =\frac{7x3}{2x1} =\frac{21}{2}$ 

And that's it. Let me know if you have any doubts :D

How many solutions exist for the given equation? 3(x - 2) = 22 -x

alexgriva [62]

There is only one solution because it is a linear equation.
3x - 6 = 22 - x
3x + x = 22 + 6
4x = 28
X = 7
