soldi70 [24.7K]
The answer is 15 because to the the lenght of the missing number you have to use the Pythagorean Theorem.So first you have to use c^2=a^2 +b^2.
25^2=20^2 + b^2 then 625=400 + b^2. 625-400= 225. So what equals 225. The answer is 15. Hope this helps

What is the solution to the system of equations? y = –3x – 2 5x + 2y = 15 (–40, 19) (–19, 55) (19, –40) (55, –19)
kobusy [5.1K]

Step-by-step Answer:

What is the solution to the system of equations?

y = –3x – 2 ..............(1)

5x + 2y = 15..............(2)

Substitute (1) in (2) to give

5x + 2(-3x-2) = 15

5x-6x-4 = 15

-x-4=15

solve for x:

-4-15 = x

x=-19

Now substitute x=-19 into equation (1)

y = -3x-2 = 57-2 = 55

Therefore the solution is (-19, 55)
