How many solutions does 4x + 2(x – 3) = 4x + 2x – 11 have?

Answers

Answer:

4x + 2(x – 3) = 4x + 2x – 11

4x + 2x - 6 = 4x + 2x - 11

6x - 6 = 6x - 11

-6 = -11

There is no solution because -6 does NOT equal -11

Answer:

0 solution

Step-by-step explanation:

4x + 2(x – 3) = 4x + 2x – 11

Solve the parentheses:

4x + 2x - 5 = 4x + 2x - 11

Subtract 2x from both sides:

4x - 5 = 4x - 11

From what you can already see that those two expressions does not equal to each other. Let’s continue solving to confirm:

(Subtract 4x on both sides)

-5 = -11

There are 0 solutions

Area of the circle: 78.54in^2

Plywood thrown away: 21.46 in^2

So the area of the square is 100 in. To find the area of a circle, you use the formula (pi)r^2 where r is the radius, in this instance it is 1/2 of ten which is 5. Then, plug it into the formula which will get you (rounded to the nearest hundred) 78.54in^2. Then, subtract from the total plywood area. Please mark brainliest :)

[tex]\frac{4}{13}[/tex]

Step-by-step explanation:

To calculate how many more questions Meta solved then Aliya you have to subtract. So you write the equation:

[tex]\frac{7}{13} - \frac{3}{13} = \frac{x}{y}[/tex]

Then, you move the 13 in place of the y.

Next, you subtract,

7 - 3 = 4. So, 4 = x
