Answer:
6. 162
7. C
Step-by-step explanation:
6. Replace the values of a and b into the expression:
8a + 6b = 8(12) + 6(11)
= 96 + 66
= 162
7. The distributive property states that whatever is outside a bracket must be multiplied to ALL terms in the brackets:
5(2f+4) = (5 × 2f) + (5 × 4)
= 10f + 20
