Step-by-step explanation:

To get from the little triangle to the big one, multiply all the litte one's sides by 3.

So the corresponding side to 4 would be 4 * 3  = 12

The area of a right triangle is 1/2 * b * h

b = 9

h = 12

Area = 1/2 * 9 * 12

Area = 54

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
