Which problem can be solved using 3 x 7= 21?

D would be the answer to solve 3x7=21. A is adding 21 with 3 and B is multiplying 3 and 21 witch isn’t what we’re looking for. Then for C, it would be subtracting 22 by 3. D is the only one witch said that Phil has 21 balloons and he put the same number of ballon on 3 tables. This way they can divide 21 with 3 and gives the quotient of 7. So D would be the best answer t solve he problem 3x7=21.

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
