Answer:

The lower left one.

Step-by-step explanation:

If you expand and rearrange it, you will find out both of its constant cancel out, and leave you with 3w=3w. So w have infinite number of solutions.

Answer:

$6(\frac{1}{2} w-1)=3(w-2)$

Step-by-step explanation:

$6(\frac{1}{2} w-1)=3(w-2)$ (Isolate parentheses)

$3w-6=3w-6$ (Add six to both sides to isolate one variable <em>w</em>)

$3w=3w$ (Divide by three to isolate variable <em>w</em>)

$w=w$

Because we got $w=w$ , that means that any number you put in for w will still get you the same answer, or "infinite answers." If you try, say 5, you would still get the same answer if you put in 9. It has infinite answers.

I hope this helped :)

A rectangular piece of paper with length 35 cm and width 14 cm has two semicircles cut out of it, as shown below.

Answer: 336.14 cm²

Step-by-step explanation:

To find the area of the rectangle after being cut, we want to find the area of the two semicircles and subtract it from the area of the rectangle. The area of the rectangle is just base times height, or 35cm times 14cm = 490cm² . Since there are two semicircles with the same diameter, we can just solve for the area of a circle and subtract it. To find the area of the circle, we need the radius, which we get by dividing the diameter by 2. After that, we calculate the radius to be 7cm, squared and multiplied by 3.14 (area of a circle) to get 153.86 cm². Subtract the areas, and we get 490 - 153.86 = 336.14 cm²
