What is the value of x in the equation 3(2x + 8) =0

Mathematics
1 answer:
Anna71 [15]2 years ago
8 0

Answer:

x=-4

Step-by-step explanation:

1. Distribute

3(2x+8)=0

6x+24=0

2. Subtract 24 from both sides.

6x+24=0

6x+24-24=0-24

3. Simplify

6x=-24

4. Divide both sides of the equation by the same term

6x=-24

\frac{6x}{6} = \frac{-24}{6}

5. Simplify

x=-4

And thats the answer.

I hope this helps        :)

Alinara [238K]

Answer:

25x^2 -1

Step-by-step explanation:

If you multiply parentheses:

(5x*5x) + (5x*-1) + (1*5x) + (1*-1)

25x^2 - 5x + 5x -1

25x^2 -1

A simpler way is to memorize this formula

(Square1 - square2)= (sqrt of square1- sqrt of square2)*(sqrt of square1 + sqrt of sqaure2)

Shona is buying a rug for her room. Store A has the rug for $45 with a 10% discount. Store B has the same rug for $46 and is off
Rudik [331]
Store A :
0.90(45) = 40.50......40.50 + .06(40.50) = 40.50 + 2.43 = 42.93

store B :
46 - 10 = 36......36 * .06(36) = 36 + 2.16 = 38.16

she would have to purchase the rug from store B...because she doesn't have enough money to purchase it from store A. She would have (40 - 38.16) = $ 1.84 in change.

I find this question to be a little misleading....because on a rebate, u dont get the discount right away....u first pay full price, and then later u get the discount mailed back to you. So actually, she wouldn't have enough money at either store.
