The number 42 and then decrease it or subtract twice what ever he has in savings. 42-(2GS) GS is goarans savings. most of the time we would use a variable like x so it could be written as 42-(2x) depends on how the teacher wants it.

Answer:
The height is 6 feet, and the length of the ramp is the hypotenuse of a right triangle with angle 28 degrees with the ground
Step-by-step explanation:sin
28=6/x
x*sin 28=6
x=6/sin 28=12.78 ft.
Answer:
x = ± √(-15n-7) / √2n (± (-15n-7)^(1/2) / (2n)^(1/2))
Step-by-step explanation:
Factoring?
2nx² + 15n+7 = 0
2nx² + 0*x + (15n+7) = 0 ... ax²+bx+c=0
Roots: x = (-2b ± √b²-4ac)) / 2a = (0 ± √0-4*2n*(15n+7)) / 4n
x = ± (√8n (-15n-7)) / 4n = ± (2√2n(-15n-7)) / 4n = ± (√2n(-15n-7)) / 2n
or x = ± √(-15n-7) / √2n
