Answer:
Step-by-step explanation:
If the side lengths of the rectangle are 3 and 12, then the area, length times width, is 36.
If the area of the square is equivalent to the area of the rectangle, then
which is the formula for the area of a square. Take the square root of 36 to get that each side of the square is 6 inches long.
Since a square has 4 sides, we get that the perimeter of that square is 4 * 6 which is 24 inches.
Answer:
Step-by-step explanation:
First of all, let's rewrite the first one after dividing both sides by 2.
Now, let's pick one you want to eliminate.
<u>Eliminating x:</u> Let's multiply the first one by 4, the second by 3, and subtract one from the other. Rest is simply solving an equation in one variable
<u>Eliminating y:</u> Let's multiply the first by 5, the second by 2, and add them together. Rest is simply solving an equation in one variable
