Answer:
x = -8, x = 5
Step-by-step explanation:
This can be solved using Factorization method:

It is c. 216 in³
to answer the problem, u must know the formula V=LxWxH (volume= length x width x height)
L=12
W=6
H=3
so, 6x3x12= 216 in³
<h2>
Rate at which area is increasing is 1.08 m²/s.</h2>
Step-by-step explanation:
Area of triangle is with side a and b and angle C between them is given by
A = 0.5 ab SinC
Here we need to find how area changes with a and b fixed and C is changing,

We have
a = 8 m
b = 9 m

Substituting

Rate at which area is increasing is 1.08 m²/s.
