h = -1 6 t ^ 2 + vt v = 120 h = - 16 t ^ 2 + 120 t h = - 4 * 4 t ^ 2 + 4 * 30 t h = 4 t ( - 4 t + 30 ) 0 = 4 t ( - 4 t + 30 ) obviously solution : t = 0 ( initial point ) and - 4 t + 30 = 0 - 4 t = - 30 - 4 t / 4 = - 30 / - 4 t = 30 / 4 = 2 * 15 / ( 2 * 2 ) = 15 / 2 = 7.5 s

Intermediate Algebra
Correct The other sides : x and x + 1 where x + 1 is the hypotenuse So Pythagorean theorem: ( x + 1 ) ^ 2 = x ^ 2 + 5 ^ 2 x ^ 2 + 2 x + 1 = x ^ 2 + 25 Both x ^ 2 get cancelled 2 x + 1 = 25 2 x = 25 - 1 = 25 - 1 = 24 x = 24 / 2 = 12 m hypotenuse x + 1 = 12 + 1 = 13 m

SORRY: A = 2 w ^ 2 + 4 w OR A = 2 ( w ^ 2 + 2 w ) OR A = 2 w ( w + 2 )

Algebra 1
A = 2 w ^ 2 + 4 w OR A = 2 ( w ^ 2 + 4 w ) OR A = 2 w ( w + 4 ) All three is same answer.

Algebra 1
A = W * L = W * ( 2 W + 4 ) = W * 2 W + W * 4 = 2 W ^ 2 + 4 W = 2 ( W ^ 2 + 4 W )

Both

Algebra 1
L = 2 W + 4 A = W * L A = W * ( 2 W + 4 ) A = 2 W ^ 2 + 4 W A = 2 ( W ^ 2 + 2 W )

Algebra 1
L = 2 W + 4 A = W * L
