Can someone plaaae quicklyalso it's 15 points so yeah

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

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)

i would be 2,000 just get the square root of 50 which is 2500 and the divid 4/5 and last thing multiply the answer you get for that by the square root of 50
