7 0

Answer:

-1.01

Step-by-step explanation:

cos^2 + sin^2 = 1

0.49 + sin^2 = 1

sin^2 = 0.51

sin = 0.71

tan = sin/cos = 0.71/-0.7 = -1.01

Is this wrong?
sammy [17]

Step-by-step explanation:

The last step is a little wrong. Lemme show you:

x(x + 2) + (x + 2)

Imagine there is an invisible '1' infront of (x + 2) like this:

= x(x + 2) + 1(x + 2)

Now we can combine the like terms together:

= (x + 1)(x + 2)

This is the correct factorization.

List multiples to find LMC of 27 and 45
PtichkaEL [24]

Answer:

135

Step-by-step explanation:

I think you mean the LCM instead of LMC. LCM stands for Least Common Multiple. Anyway, some of the multiples of 27 are 27, 54, 81, 108, and 135. Some multiples for 45 are 45, 90, 135. We can see here that 27 and 45 share the mutiple of 135 which is the first number they have in common.
