The answer that you have is most likely right, since the grouping did not change.
Perimeter is the sum of all the sides of the shape
do you know the length of each side of the parallelogram?
Answer: the answer is the first one!!
Step-by-step explanation: split the shape up and multiple the numbers that came with the problem and then put all the totals together i got a total of 364!! Hope that helps!!
You plug in the point into each equation to see if the answer comes out equal. Such as the first one, so you have y=-3/4x+1. So you plug in the -4 for the x then plug in the -2 for y. So you get -2=1.1875, as you see both sides don't add up. As you progress in Algebra I'm guessing that you're in, you'll progress as the year goes on. So your answers are 3x-4y=-4 and y+2=3/4(x+4).
7.846 decomposed is:
7 + 0.8 + 0.04 + 0.006
or, to see it more clearly:
7.000 + 0.800 + 0.040 + 0.006
Rounded to the nearest tenth: 7.8
Rounded to the nearest hundredth: 7.85
I hope that's what you meant :)
