Step-by-step explanation:
The significant figures of a number that carry meaningful contribution to its measurement resolution
The height would be 36cm. This is the case because to find the height, first multiply the volume by 2 (You are working backwards from the formula). Then divide it by the base edge (15). You will get 36cm.
Answer:
The perimeter of this rectangle is 14x + 10
Step-by-step explanation:
You want to add all of the sides together.
First, you add 4x-2 and 3x+7
4x-2 + 3x+7 = 7x+5
Then, you multiply this answer by two, since there are two of each side with each value.
(7x+5) * 2
7x * 2 = 14x
5*2 = 10
So, (7x+5) * 2 = 14x + 10
14x + 10 is your final answer

If you change the y-intercept but keep the slope the same, it just moves the line up or down. Since the lines would have the same slope (same rate of change), the two lines would be parallel.
