It's past my bed-time and there's a whopping 5 points at stake, so
I'm going to violate my own #1 Prime Cardinal Rule here, and just
give a stripped down answer without going through a full explanation.

The number of combinations of 3 cows out of 7 is (7·6·5) / 3!  = 35 .

The number of combinations of 2 pigs out of 4 is  (4·3)/2  =  6

The number of combinations of 10 sheep out of 10 is  1 .

The number of ways he can select his animals is (35 · 6 · 1)  =  210 .

The equation 3d+2=29 can be used to find the height of a bean plant days after it was purchased. How many days has it been since the plant was purchasedA)7.6 days

Answers

If you simply solve the equation you find that the letter D is equal to 9. We have no idea what that tells us about bean plants because you haven't explained anything about how the equation can be used.

The first three steps for solving the quadratic equation by completing the square are shown. Fill in the missing number in the last step.9x2 +54x = 7

9(x2 + 6x) = 7

9(x2 + 6x + 9) = 7 +.?

Answers

Completing the square is done as follows:

1. Write the equation in a way that the constants are in the right side while the terms with x are on the left. 
9x2 +54x = 7

2. Make sure that the coefficient of the x^2 term is 1.
9(x2 + 6x) = 7

3. Adding a term to both sides that will complete the square in the left side. This is done by dividing the coefficient of the x term by 2 and squaring it. Note: The same amount should be added to the right side to balance the equation.
9(x2 + 6x + 9) = 7 + 81

9(x+3)^2 = 88

Answer:

? = 81
