−2(−3x+4)+3x−3=−29 what does x equal
gogolik [260]

Answer:

x = −2

Step-by-step explanation:

Let's solve your equation step-by-step.

−2(−3x+4)+3x−3=−29

Step 1: Simplify both sides of the equation.

−2(−3x+4)+3x−3=−29

(−2)(−3x)+(−2)(4)+3x+−3=−29(Distribute)

6x+−8+3x+−3=−29

(6x+3x)+(−8+−3)=−29(Combine Like Terms)

9x+−11=−29

9x−11=−29

Step 2: Add 11 to both sides.

9x−11+11=−29+11

9x=−18

Step 3: Divide both sides by 9.

9x /9  =  −18 /9

x=−2

I hope this helps!!!

Anyone help please I need it
andreev551 [17]

Answer:

-10+i\sqrt{2}

Step-by-step explanation:

One is given the following expression:

\sqrt{4}-\sqrt{-98}-\sqrt{144}+\sqrt{-128}

In order to simplify and solve this problem, one must keep the following points in mind: the square root function (\sqrt{}) is a way of requesting one to find what number times itself equals the number underneath the radical sign. One must also remember the function of taking the square root of a negative number. Remember the following property: (\sqrt{-1}=i). Simplify the given equation. Factor each of the terms and rewrite the equation. Use the square root property to simplify the radicals and perform operations between them.

\sqrt{4}-\sqrt{-98}-\sqrt{144}+\sqrt{-128}

\sqrt{2*2}-\sqrt{-1*2*7*7}-\sqrt{12*12}+\sqrt{-1*2*8*8}

Take factors from out of under the radical:

\sqrt{2*2}-\sqrt{-1*2*7*7}-\sqrt{12*12}+\sqrt{-1*2*8*8}

2-7i\sqrt{2}-12+8i\sqrt{2}

Simplify,

-10+i\sqrt{2}
