a)
- remove first parentheses and add: -6×[-12+26] =-6×[14]
- remove third parentheses and multiply:-6×14=-84
c)
- remove first parentheses and add:(6)×[-17+28]=6×[11]
- remove third parentheses and multiply: 6×11=66

Step-by-step explanation:
Answer:
3i + 63j
Step-by-step explanation:
Step 1: Replace the variables with the given statements
5(3i+9j) - 3(4i-6j)
Step 2: Distribute
15i + 45j -12i + 18j
Step 3: Combine like terms
3i + 63j
Answer: 4.75 lbs is 2,154.56 grams
First you distrbut the 5 which would give you
then you distribut the 3
then you solve for x
5x-30=3x-15
5x=3x-45
2x=45
x=22.5
