Well I believe the answer is A. instead of B,C, or D,
This is because you would not need to multiply right away. The problem addresses that John buys 5 more which means to add and if you needed to multiply right away it would have said twice as much or greater to for an increasive value.
Solution: 2×45+5=f
850,000 and 950,000 if I understand the question correctly
Answer:
6.357
Step-by-step explanation:
This is probably wrong
When an exponent is outside the parenthesis, you multiply them.
13*19=247
“C” 2^247 is the answer.

Answer:
B
Step-by-step explanation:
We can see in the expression that there are 2 x² blocks, 4 -x blocks, and 3 -1 blocks. Therefore, we can write this as
2 * x² + 4 * (-x) + 3 * (-1) = 2x²-4x-3
Comparing this with each answer, we have
A: x²-2x-4 + x² + 2x-1 = 2x²-5. This is not correct
B: 3x²-7x+1-(x²-3x+4) = 3x²-7x+1 -x²+3x-4 = 2x²-4x-3. This seems correct but we can check the other answers to be sure
C: (2x+1)(x-3) = 2x²-6x+x-3 = 2x²-5x-3. This is incorrect
D:
. This is incorrect
