Answer:
4
Step-by-step explanation:
2x2=4
Answer:
-24xy+ 162x²y +168xy²
Step-by-step explanation:
[4-7(3x+4y)] • 3x(-2y) =
(4-21x-28y) • (-6xy)=
4•(-6xy) -21x•(-6xy)-28y•(-6xy)=
-24xy+ 162x²y +168xy²
If the sine if 4/5, then the side opposite is 4 and the hypotenuse is 5. This means it's the 3, 4, 5 right triangle (or similar, such as 6, 8, 10).
cos = 3/5
tan = 4/3
cot = 3/4
sec = 5/3
csc = 5/4
The answer would be f-1(x)=x^2-3
Hope it helps
