Question

Find the product
−1(2x+10)
is
−2x−10
.

Answer 1

yes you are correct. this is due to the distributive property of multiplication.

`a(b+c)=ab+ac`
so
`-1(2x+10)=-1(2x)+(-1)(10)`

`=-2x-10`

Answer 2

Yes, that is correct due to the distributive property. It states that you can distribute a number to another number.
for example: a(b + c) = ab + ac
in this case, you are distributing the -1 into the 2x + 10
-1(2x + 10)
(-1) * (2x) + (-1) * (10)
(-2x) + (-10)
-2x - 10
