A cumparat 5 prajituri cu vanilie si 7 cu ciocolata.
Answer:
12
Step-by-step explanation:
8x - 32 = 6 - 9x
17x = 38
x = 38/17
7a^3(6a^2 + a)^2 - 4a^6
All we have to do here is basically add and subtract exponents!
(6a^2 + a)^2 = 36a^4 + a^2
7a^3(36a^4 + a^2) - 4a^6
252a^7 + 7a^5 - 4a^6
Answer is C.
