Let the common multiple be x
3x : 2x
3x = 125
x = 125/3

So, B pays 2x = 2 × 125/3 = £250/3

Factor completely 3X^2 -25​
Dominik [7]

In order to factor a polynomial, you have to find its roots

x_1,\ x_2,\ldots,x_n

So that you can factor it as

p(x)=(x-x_1)(x-x_2)\cdots(x-x_n)

So, in this case, we're looking for the solutions of

3x^2-25=0 \iff 3x^2=25 \iff x^2 = \dfrac{25}{3} \iff x=\pm\sqrt{\dfrac{25}{3}}=\pm\dfrac{5}{\sqrt{3}}

So, the polynomial can be written as

3x^2-25 = \left(x-\dfrac{5}{\sqrt{3}}\right)\left(x+\dfrac{5}{\sqrt{3}}\right)

What is 4(x-7)=2(x+3)?
hram777 [196]

Answer:

Isolate the variable by dividing each side by factors that don't contain the variable.

4(x−7)=2(x+3)

Simplify both sides of the equation.

4(x−7)=2(x+3)

4x+−28=2x+6

4x−28=2x+6

Subtract 2x from both sides.

4x−28−2x=2x+6−2x

x−28=6

Add 28 to both sides.

2x−28+28=6+28

2x=34

Divide both sides by 2.

2x/2  =  34/2

x = 17
