450 in. squared. after you get 15, substitute it for x in the length and width. this means you would have 2(15) X (15) whixh equals 450 in. squared
Answer:
A = 156 in ^2
Step-by-step explanation:
A of a rectangle is given by
A = l*w
A = 12*13
A = 156 in ^2
Ah what does this slope look like and what are the options..?
When
the ball is in the ground, its height is basically equal to zero thus making
our equation,
<span> -16t^2 + 272t + 1344 = 0</span>
Simplifying
the equation will give us,
<span> - t^2 + 17t + 84 = 0 or t^2 – 17t – 84 = 0</span>
Factoring
out the equation will give us,
<span> (t – 21)(t + 4) = 0</span>
Thus,
t = 21 or t = -4. -4 is an extraneous root. Thus, the answer is t = 21.
<span>Answer:
21 seconds</span>
