Step-by-step explanation:
L.H.S
tanA * cosecA
=sinA/cosA * 1/sinA
now cancel sinA and sinA
then,
1/cosA
= secA
= RHS
hence proved
Answer:
x=8
Step-by-step explanation:
(8x+12)=76
8x=64
x=8
check
8(8)+12=104
64+12=76
76=76
Answer:
-2b^2+3b
Step-by-step explanation:
You just have to add like terms, which is the single numbers, the numbers with just the variables, and the numbers with variables that are squared.
Add up all the 'x's: (1 of them) plus (3 of them) = 4 'x's
Add up the just-plain-numbers: 93 + 18 = 111
Write them together: 4x + 111
No, this is not a function because it does not have any equal values.
