The perimeter is 10 try to draw these points on the graph and count the distance between each or you can just look at the coordinates and find the distance and then add length and width
The answer would be 140 because if you subtract 710 from 850 you would get 140.
Answer:
Step-by-step explanation:
Janelle expanded the expression as shown below. -4(-3x + 2/7) = -12x - 3 5/7 What errors did she make?
We are given the expression:
-4(-3x + 2/7)
Solving this expression:
Expanding the brackets
-4 × -3x + -4 × 2/7
12x - 8/7
12x - 1 1/7
Answer:
x = -1
y = -6
Step-by-step explanation:
7x - y = -1 -> y = 1 + 7x
7x + 3y = - 25
Put y = 1 +7x -> 7x + 3(1 +7x) = -25
-> x = -1
-> y = -6
