Select the correct difference. 5d^2 + 4d - 3 less 2d^2 - 3d + 4
7 d^2 + 7 d - 7
3 d^2 - 7 d - 7
3 d^2 + 7 d - 7
7 d^2 + d + 1

3 d^2 + 7 d - 7

Step-by-step explanation:

5d^2 + 4d - 3 less 2d^2 - 3d + 4

correct difference

3 d^2 + 7 d - 7

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
