Answer:
<em>f=-14.4</em>
Step-by-step explanation:

5x2y-5x2+3yx2-3y2+x2-y2+8xy2-3y2
First Collect like terms:
5x x 2y, +3x x 2,and +8xy x 2
16x x 2y -4x x 2 - 4y x 2—> Multiply the numbers:
Multiply the numbers 16 x 2
16 x 2 = 32
Now multiply the numbers 4 x 2
4 x 2 = 8
Now Multiply the numbers 4 x 2 again
4 x 2 = 8
= 32xy - 8x- 8y
Factor 8 from the expression
Final Answer:
8(4xy-x-y)

Answer:
16.4
Step-by-step explanation:
The law of cosines is useful here. It tells you ...
b^2 = a^2 + c^2 -2ac·cos(B)
b^2 = 22^2 +10^2 -2·22·10·cos(44°)
b^2 ≈ 267.49
b ≈ √267.49 ≈ 16.35514
b ≈ 16.4
