Answer:

Step-by-step explanation:

No she is not correct because 2 times 3a is 6a and -2 times 2 is -4. And then 6a plus 4a is 10a. So therefore the equation would be 10a -4 which is not equivalent to 10a -2. Hope this helps you

No, she's not correct. The first expression is equal to 2 and the second expression is equal to 12. So, it's NOT CORRECT.

AB = x - 10, BC = x + 2, and AC = 28. Find BC.<br><br>Please help!

Leno4ka [110]

Answer:

BC = 20

Step-by-step explanation:

AC = AB + BC

28 = x-10 + x+2

Combine like terms

28 = 2x -8

Add 8 to each side

28+8 = 2x-8+8

36 = 2x

Divide by 2

36/2 = 2x/2

18 =x

We want to find BC

BC = x+2

=18+2

=20
