Solve for t.
2t2 - 3 = 15
2t2 = 18
t2 = 9
t = +/- 3
Solve for a.
v1 = v0 + at
v1 = v0 + at
v1 - v0 = at
a= (v1 - v0)/t
Solve for x.
a2 + b2 = c292 + x2 = 25281 + b2 = 625b2 = 544b = 23.3

Solve for H.
cos q = A/H
cos = A/HHcos = AH = A/ cos
Solve for x.
sin = O/Hsin(50) = x/15x = 11.5orcos = A/Hsin(40) = x/15x = 11.5

Solve for y.
y2 + 3y = 10
y2 + 3y – 10 = 0
(y + 5)(y – 2) = 0
y = 2, -5
