Exercise 1 Page 49

Practice makes perfect
a Using the Distributive Property, we can multiply each term inside the parentheses by 7.
(j+2)7
Distr

Distribute 7

j(7)+2(7)
Now that we have rewritten the expression, we can simplify our answer.
j(7)+2(7)
Multiply

Multiply

7j+14
b Using the Distributive Property, we can multiply each term inside the parentheses by - 8. Be careful when multiplying negative terms.
- 8(x-3)
Distr

Distribute - 8

x(- 8)-3(- 8)
Now that we have rewritten the expression, we can simplify our answer.
x(- 8)-3(- 8)
MultNegNegOnePar

- a(- b)=a* b

x(- 8)+3* 8
MultPosNeg

a(- b)=- a * b

- x* 8+3* 8

- 8x+24
c Using the Distributive Property, we can multiply each term inside the parentheses by - 1. Be careful when multiplying negative terms.
- (4-c)
Distr

Distribute - 1

4(- 1)-c(- 1)
Now that we have rewritten the expression, we can simplify our answer.
4(- 1)-c(- 1)
MultNegNegOnePar

- a(- b)=a* b

4(- 1)+c* 1
MultPosNeg

a(- b)=- a * b

- 4* 1+c* 1
Multiply

Multiply

- 4+c
d Using the Distributive Property, we can multiply each term inside the parentheses by - 1. Be careful when multiplying negative terms.
- (11+2b)
Distr

Distribute - 1

11(- 1)+2b(- 1)
Now that we have rewritten the expression, we can simplify our answer.
11(- 1)+2b(- 1)
MultPosNeg

a(- b)=- a * b

- 11(1)-2b(1)
Multiply

Multiply

- 11-2b
