In this question the answer is x is equal to exactly 1.749... Or 1.75
35
the ratio for the two is 5:7 and you want to find _:49. to get from 7 to 49 you multiply the 7 by 7. because you did that to one side you have to do the same to the other and multiply 5 by 7 which gives you 35
Point Form:
(2, 4), (1, 1)
Equation Form:
x = 2, y = 4
x = 1, y = 1

bear in mind that, though the square has two valid roots, one negative and one positive, the hypotenuse is just a radius distance, and therefore is never negative.
Would it be 7/1 or anything greater than one
