-2 (5x - 6) how do I solve this

1 answer:

6 0

When you have an algebraic expression including brackets, you always multiply what's on the inside by what is on the outside. This means that you would do -2 × 5x = -10x, and then -2 × -6 = 12, so your answer would be -10x + 12.

I hope this helps!

Step-by-step explanation:

Complementary= 90 degrees

Supplementary= 180 degrees

Looks like you got both of those. Good job!

<1 + <2 = 90

<1 = 55

90-55=35

<2=35

<2+ <3= 180

180-35= 145

<3 = 145 degrees

You did awesome! Amazing job!

Answer for the square root(5x-9)+1=x

Evgen [1.6K]

$\bf \sqrt{5x-9}+1=x\implies \sqrt{5x-9}=x-1\implies 5x-9 = (x-1)^2 \\\\\\ 5x-9=\stackrel{\mathbb{FOIL}}{x^2-2x+1}\implies 5x=x^2-2x+10\implies 0=x^2-7x+10 \\\\\\ 0=(x-5)(x-2)\implies x= \begin{cases} 5\\ 2 \end{cases}$
