Answer:
156.5
Step-by-step explanation:
Thinking process:
The area can be calculated using the formula:
We let the substitution take place.
Therefore, we let
Thus,
So,
Also, the interval of the integration changes to [ 37, 65]
Thus,
=
= 156.5 units²
Y=42 Y=?
X=6 X=3
cross multiply
so 42times3=6timesY
126=6Y
Y=126 divided by 6
=21
Step-by-step explanation:
x-intercept => point (2, 0)
y-intercept => point (0, -4)
We cannot see the triangle
