Answer:
1) 25
2) (5+4)×2+6-(2×2)-1
Step-by-step explanation:
1) do exponents: 6×7-9×9+64,
do multiplication: 42-81+64,
do add & subtract: 25
2) (5+4)×2+6-(2×2)-1
(9)×2+6-(4)-1
18+6-4-1
=19
8x^5 +4x^2 - 12
= 4(2x^5 + x^2 -3)
answer is A
Step-by-step explanation:
If 3n+10=3
... 3(12)+10=46?
The answer would be the algebraic expression, b + 9. The
translation here is b is representing the number of blue bikes then you needed
to add the 9 which represents the 9 red bikes. The two is added together, to get
the total of those red and blue bikes which we are looking for.
