Answer:
Area =
Step-by-step explanation:
The function is the area function of a rectangle.
Area of Rectangle = Length * Width
Length of fabric scrap = 5x
Length of rectangular patchwork will be 5x + 3
and
Width of fabric scrap = 2x
Width of rectangular patchwork will be 2x + 5
THus, Area = (5x+3)(2x+5) square feet.
Let's expand:
You can parameterize the curve
and compute the integral along each component curve, or you can use the fact that
is the continuous gradient of a function
and observe that the line integral is path independent.
In other words, there is a function
such that
, so the integral along any curve
from the points
to
is simply
You have
, and so
while
where
is an arbitrary constant. So we've found that
which means the line integral has a value of
Are those the only answer choices? The answer is -4a^2 - a + 14
Answer:
9 x 6 = 54, 54 divided by 2 = 27
27 x 4 = 108
Just find the area of one triangle then multiply by 4 since there 4 triangles.
