2(7x+3-x) i need help

Mathematics
1 answer:
Neko [114]2 years ago
3 0

Answer:

See explanation.

Step-by-step explanation:

I'm assuming your question is to simplify the given expression. I will work that problem and also I will solve for x just in case that's your question instead.

Step 1: Simplify inside parenthesis

7x + 3 - x = 6x + 3

Step 2: Multiply simplified expression by number outside parenthesis

2 * (6x+3) = 2*6x + 2*3

12x + 6

Simplification is done after this step.

Step 3 (unnecessary if the problem is to simplify the expression): Solve

12x + 6 = 0

12x = -6

x = -1/2

Since there was no term given on the other side of the equal sign, I assumed that term was zero.

stans steakhouse has a sever to chef ratio of 5 to 2 the total number of severs and chefs is 42.How many severs does stans steak
amm1812

Answer:

30

Step-by-step explanation:

We need to figure out what 5 and 2 really mean in this scenario. So we add them together. 5+2=7

We then divide 42 by 7. 42/7=6

Afterward we multiple 5 by 6 to get the real number or servers. 5x6=30

And as a bonus (and also to check our work) we multiple 2 by 6. 2x6=12

5/2=30/12

For what values of x and y is the equation (x2 + y2)2 = (x2 – y2)2 + (2xy)2 true?
denis-greek [22]

Answer:

A) all values of x, and all values of y

B) (3a + 4b) (9a² − 12ab + 16b²)

Step-by-step explanation:

(x² + y²)² = (x² − y²)² + (2xy)²

x⁴ + 2x²y² + y⁴ = x⁴ − 2x²y² + y⁴ + 4x²y²

x⁴ + 2x²y² + y⁴ = x⁴ + 2x²y² + y⁴

27a³ + 64b³

(3a)³ + (4b)³

(3a + 4b) (9a² − 12ab + 16b²)
