Answer:
21.3
Step-by-step explanation:
It's easier to see how to do this if you transfer the 11 to the bottom of the rectangle. The look at the left triangle. It has 3 sides.
24, 11, and a.
You should be able to find a using
a^2 + 11^2 = 24^2 Expand the squares
a^2 + 121 = 576 Subtract 121 from both sides
a^2 = 576 - 121
a^2 = 455 Take the square root of both sides.
sqrt(a^2) = sqrt(455)
a = 21.33
or
a = 21.3
The answer to m2=91 is 40.5
You can just look at it and already tell it’s B
Answer:
5 inches wider
Step-by-step explanation:
The given area expression factors as ...
x² +2x -15 = (x -3)(x +5)
Apparently, we're to assume that these factors represent length times width, and the factor x-3 corresponds to a length that is 3 inches shorter than the old length (x). Then the width is (x+5), which is 5 inches wider than the old length.
Answer:
Step-by-step explanation:
3u=y/x^2-d^2
3u=y-(xd)^2/x^2
u=y-(xd)^2/3x^2
