Answer:
17 x + 28
Step-by-step explanation:
Simplify the following:
2 (x + 5) + 3 (5 x + 6)
Hint: | Distribute 2 over x + 5.
2 (x + 5) = 2 x + 10:
10 + 2 x + 3 (5 x + 6)
Hint: | Distribute 3 over 5 x + 6.
3 (5 x + 6) = 15 x + 18:
10 + 2 x + 18 + 15 x
Hint: | Group like terms in 10 + 2 x + 18 + 15 x.
Grouping like terms, 10 + 2 x + 18 + 15 x = (2 x + 15 x) + (10 + 18):
(2 x + 15 x) + (10 + 18)
Hint: | Add like terms in 2 x + 15 x.
2 x + 15 x = 17 x:
17 x + (10 + 18)
Hint: | Evaluate 10 + 18 using long addition.
