Answer:

N/A

Step-by-step explanation:

We should first simplify the right side, and doing so will get x/3+6=x/3+10. WE then subtract x/3 on both sides to get 6=10. Since this cannot be true, there are no solutions.

Answer:

no solution

Step-by-step explanation:

[tex]\frac{x}{3}[/tex] + 6 = 2([tex]\frac{x}{6}[/tex] + 5) ← distribute parenthesis by 2

[tex]\frac{x}{3}[/tex] + 6 = [tex]\frac{x}{3}[/tex] + 10 ( subtract 6 from both sides )

[tex]\frac{x}{3}[/tex] = [tex]\frac{x}{3}[/tex] + 4 ( subtract [tex]\frac{x}{3}[/tex] from both sides )

0 = 4 ← False statement

This indicates the equation has no solution

Step by step :

x² = 12² + 10²

x² = 144 + 100

x² = 244

x = 15,6m✔

x² = 12² + 10²

x² = (12 × 12) + (10 × 10)

x² = 144 + 100

x² = 244

x = √244

x = 15,6 m

Answers

I think the answer is 32 maybe

Solution:

The length of a side of a square is 4x – 1.
Express the area of the square in terms of x.

Answers

Answer:

16x^2 - 8x + 1

Step-by-step explanation:

1. The area of a square can be represented as s^2 or (s)(s), where s = side.

2. (Solving)

Step 1: Set up expression

[tex](4x-1)^2[/tex] [tex](4x-1)(4x-1)[/tex]

Step 2: Apply the FOIL method (first, outside, inside, last)

[tex](4x)(4x)+(4x)(-1)+(-1)(4x)+(-1)(-1)[/tex] [tex]16x^2 -4x -4x +1[/tex]

Step 3: Simplify.

[tex](16x^2)+(-4x-4x)+(1)[/tex] [tex]16x^2 -8x + 1[/tex]

Therefore, the area of the square in terms of x is 16x^2 - 8x + 1.

when 7 is added to 3 times a number, the sum is multiplied by 2 and 15 is subtracted what is the final answer

Answers

Answer:

2(3x+7) -15

Step-by-step explanation:

Let x = unknown number

7 is added to 3 times a number

3x+7

Multiply the sum by 2

2(3x+7)

Subtract 15

2(3x+7) -15

Answer:

Let the required number be " x "

Now, 7 is added to 3 times a number : (3x + 7)

Next, the sum is multiplied by 2 : 2(3x + 7)

And then, 15 is substracted from it : 2(3x + 7) - 15

2(3x + 7) - 15 is the final answer.
