Factor completely 5x2 – 50x + 120

1 answer:

5 0

The answer is 5(x - 4)(x - 6)

5x² – 50x + 120 = 5*x² - 5*10x + 5*24
= 5(x² - 10x + 24)
= 5(x * x - 4x - 6x + 6*4)
= 5(x(x - 4) - (6x - 6*4))
= 5((x(x - 4) - 6(x - 4))
= 5(x - 4)(x - 6)

What is the value of 10x+1 3

Veseljchak [2.6K]

SOLUTION

In this question, we are meant to expand the expression:

$(10x+1)^{3\text{ }}\text{ = ( 10 x + 1 ) (10 x + 1 ) ( 10 x + 1 )}$ $\begin{gathered} (10x+1)(10x+1)=100^{}x^2\text{ + 20 x + 1} \\ \text{Then,} \\ (100x^2+20x+1)(10x+1)=1000x^{3\text{ }}+200x^2+10x+100x^2\text{ + 20 x + 1} \\ \text{ = 1000 x}^{3\text{ }}\text{ + }300x^2\text{ + 30 x + 1} \\ \\ \text{CONCLUSION: ( 10 x + 1 )}^{3\text{ }}=1000x^{3\text{ }}+300x^2\text{ + 30 x +1} \end{gathered}$

Nine times the difference of a number and one is equal to seven less than two times the number

Oksana_A [137]

9*(x-1)=2x-7
First get rid of your parenthesis by distributing.
9x-9=2x-7
Then all you have to do is isolate the variable
9x=2x+2
7x=2
so x= 2/7
