My calculator wasn’t working for this I’m not sure how to solve it but help would be coolio
ziro4ka [17]

We know that:

_nP_k = \dfrac{n!}{(n-k)!}

so in this case n = 5, k=3 and:

_5P_3=\dfrac{5!}{(5-3)!}=\dfrac{5!}{2!}=\dfrac{5\cdot4\cdot3\cdot2\cdot1}{2\cdot1}=\dfrac{120}{2}=\boxed{60}

-2-5(4n-6)=-132 not really sure how to do this one ..
uranmaximum [27]

All you have to do is follow PEMDAS (if you don't know what that is, search it up).


-2-5(4n-6)=-132

Distribute the 5 to everything in the parentheses.

-2-20n+30= -132

Combine like terms.

-20n+28 = -132

Subtract 28 from both sides.

-20n = -160

Divide by -20 on both sides.

n = 8
