Step-by-step explanation:

The two will add to 90 degress so

6x+17+3x-17=90 combine like terms

9x=90 divide by 9 to isolate the x

x=10

Now sub it into each equation to solve

ABC = 6(10)+17 = 60+17 = 77

CBD = 3(10)-17 = 30-17 = 13

Check = 77+13 = 90 Correct

7 times a number is 18 less than the square of that number. Find the positive solution.

Arte-miy333 [17]

So 7 x = x2 -18 so you get the quadratic x^2 -7x -18 and then get 2 x -9= -18 and 2 + -9 = -7 so you get (x + 2) ( x - 9) so the positive solution would be x-9 = 0 so x= 9. Hope this helps :)
