Answer:

x = 7/2

Step-by-step explanation:

Solve for x over the real numbers:

(3 x - 2) (x + 4) - 3 (x + 5) (x - 1) = 0

Expand out terms of the left hand side:

7 - 2 x = 0

Multiply both sides by -1:

2 x - 7 = 0

Add 7 to both sides:

2 x = 7

Divide both sides by 2:

Answer: x = 7/2

If a ball is thrown into the air with a velocity of 42 ft/s, its height (in feet) after t seconds is given by y = 42t − 16t2. Fi

Andru [333]

$\bf y=42t-16t^2\implies \left. \cfrac{dy}{dt}=42-32t \right|_{t=1}\implies 42-32\implies 10$
