1. Use the Pythagorean Theorem because this is a right triangle:
a^2 + b^2 = c^2
34^2 + 23^2 = c^2
√ 1685 = c
c = 41
answer: 41
The perimeter of rectangle is 2L + 2W where L is length and W is width.
Then substitute and evaluate:
2(2x + 7) + 2(3x + 8y)
4x + 14 + 6x + 16y
10x + 16y + 14
Answer:
250
Step-by-step explanation:
Original cost * percent of the item = new price
Original *80% = 200
Change to decimal form
original *.80 =200
Divide each side by .80
original *.80/.80 = 200/.80
original =250
Yes, because 2/4 reduces to 1/2 and so does 3/6
