Answer:
20?
Step-by-step explanation:
I think this is the steps your looking for.
To find the slope, we can use the formula m = y change/x change. Since we already have 2 points, we can subtract the second coordinates from the first ones.
1. (-18-(-18))/(15-6) = 0/9 = 0. m=0x
2. (16-12)/0-8) = 4/-8 = -1/2. m = -1/2x
Hope this helps.
The difference between the y-coordinates is 7 units. If the area is to be 42 square units, the missing coordinates must be 42/7 = 6 units to the right of those shown.
B = A +(6, 0) = (-4, 4) +(6, 0) = (-2, 4)
D = C +(6, 0) = (-4, -3) +(6, 0) = (-2, -3)
The appropriate choice is the last one, ...
(-2, 4) and (-2, -3)
The question is a little confusing. I would probably say multiplication? You need to divide both by 6, because she wants 6 pieces to fit into both values. So 66/6=11 and 36/6=6. Then I suppose a subtraction to find the difference, which would be 11-6=5, so 5 inches difference between one piece of pink and one piece of white. Hope I got this right and that was actually what the question was asking haha. Sorry if not
