Answer:
Width = 12 feet
Length = 20 feet
Step-by-step explanation:
The area of a rectangle is A = l*w. Here the length is 8 feet more than the width or 8 + w and the width is w. So the area is A = w(8+w) = 8w + w²
If the dimensions are changed then the expressions will change. The width is increased by 4 feet. This means the width w becomes w + 4. The length is decreased by 5 feet. This means the length becomes 8 + w - 5 = 3 + w. So the area of the new triangle is A = (w+4)(3+w) = w² + 7w + 12.
Since the areas are the same, set them equal to each other and solve for w.
w² + 7w + 12 = 8w + w² Subtract w² from both sides.
7w + 12 = 8w Subtract 7w from both sides.
12 = w
The original width w is 12 feet. This means the original length which was 8 + w = 8 + 12 = 20 feet.
First take numbers on side :
I think the answer is x2 + 3x -28 and the x2 is x to the POWER of 2
Answer:
D. Both B and C
Step-by-step explanation:
The government will give the same amount of available social security number to each state. So the available social security number pool will be divided by the total number of states. There are a total of 50 states in the USA. If the number pool is 5 x 10^9, then each state going to have:
5 x 10^9 /50= 0.1 * 10^9 = 1*10^8
The answer will be D since 1 x 10^8 and 100,000,000 is the same number
A. The distance traveled each hour would be the total distance divided by the number of hours.
