Question

Simplify: –6 – 7(c + 10)
A.)64 – 7c
B.)–76 – 7c
C.)4 – 13c
D.)–16 – 13c

Answer 1

-6 -7(c +10) distribute the -7
-6 -7c -70 ======the - 7 makes that a minus even though it says plus since a neg times a pos = a a neg
then combine like terms
-76-7c

Answer 2

2x + 3(x – 2) – 3(x – 6)

Answer 3

2(x+6)

Answer 4

again distribute then collect like terms
2x + 3(x-2) - 3(x-6)
2x+ (3x -6) -3x + 18
the 3x will cancel with -3x
2x-6+18
2x+12

Answer 5

When you have an equation like this with paranthesis ALWAYS use distributive property, then add like terms, then solve for the variable
