Answer:
Step-by-step explanation:
Did you find the answer
Multply both equations by 2 leaving
x + 2y = 8
x - 2y = -2
Add the equations giving
2x = 6
x = 3
Substitute 3 in the top equation
3 + 2y = 8
2y = -5
y = -2.5
Answer:
14.14 i hope this helps lol ;)
Answer:
If you've learnt sin(A+B) = sinAcosB + cosAsinB,
sin(4u)
= sin(2u+2u)
= sin(2u)cos(2u) + cos(2u)sin(2u)
= 2 sin(2u) cos(2u).
The answer is D) 3,404
By putting the table values into the progam DESMOS, and then putting in the formula, the answer will be given- and that answer is 3,404.
