So you make them into an improper fraction with a common denominator. so it would be 18/4 - 7/4, and it equals 11/4, or 2 & 3/4!
The sides of the triangle are 3x, 4x and 5x
3x + 4x + 5x = 90
12x = 90
x = 90/12
x = 7.5
first side = 3x = 3 * 7.5 = 22.5 cm
second side = 4x = 4 * 7.5 = 30 cm
third side = 5x = 5*7.5 = 37.5 cm
The scale factor of the dilation is 2
Answer: B. 89
Step-by-step explanation:
-29.202x7= -204.414
-204.414+293.5= 89.086
So the answer is B. 89
This dot plot shows a nonlinear association... this is because if you look at the plot you can tell that there isn’t a line going any direction, it’s kinda scattered..so there isn’t any outliers rather it’s a nonlinear plot
