2(x + 3) = x - 4

distribute

2x + 6 = x - 4

either subtract 6 from both sides or add 4. i will be subtracting 6.

2x = x - 10

subtract x from both sides

x = -10

A projectile is shot vertically from the ground level. It’s height h, in feet, after t seconds is given by h = 88t - 16t ^2. How

kozerog [31]

Answer:

it will take 5.5 seconds to hit the ground

Step-by-step explanation:

A projectile is shot vertically from the ground level. It’s height h, in feet, after t seconds is given by $h = 88t - 16t ^2$

When the projectile hits the ground then the height becomes 0

$h = 88t - 16t ^2$

$0 = 88t - 16t ^2$

GCF is -8t

$0 = 8t(11 - 2t)$

now set each factor =0 and solve for t

$8t=0, t=0$

$11-2t=0, t=\frac{11}{2}$

So it will take 5.5 seconds to hit the ground
