Step-by-step explanation:
Answer:
2x² + 19x + 45
Step-by-step explanation:
(x + 5)(x + 1) + (x + 5)(x + 8) ← expand both sets of factors using FOIL
= x² + 6x + 5 + x² + 13x + 40 ← collect like terms
= 2x² + 19x + 45
When you add 4 to 25 you get 21 then subtract 11 and get 10 and then add 15 which is equal to 25 and then subtract 13.
the answer is 12
The answer to this problem is 164.
