Trees are being planted in an area of land that measures approximately three acres. One acre contains 43,560 square feet, if one
kobusy [5.1K]
1 yard = 3 feet, so    2yds x 1yd    is the same as    6ft x 3ft, or 18 square feet

If one acre contains 43,560 square feet, and the question asks how many trees can be planted per acre, then all we have to do is divide 43,560 by 18:

43,560 ÷ 18 = 2420 trees

So, the answer is A) 2,420.

A pair of vertical angles has measures<br> (3x + 4) and ( 73 – 9)<br> What is the value of x?
sergij07 [2.7K]

Answer:

20

Step-by-step explanation:

Vertical angles are always equal to each other. So the answer is

3x + 4 = 73 - 9                 Are you sure this is what the question is?

3x + 4 = 64                      Subtract 4 from both sides

 <u>    -4      -4</u>

3x = 60                           Divide by 3

3x/3 = 60/3

x = 20

True or false The coefficient of (x^(k)) (y^(n-k)) in the expansion of (x+y)^n equals (n choose k)
Setler [38]
This is under the binomial theorem. A binomial theorem is an equation that predicts the sequence when a binomial is raised to certain power. The general form of the equation is (a+b)^n. The equation for the binomial theorem would be

nCk a^(n-k) b^k, where k is the kth term of the expanded form, n is the nth power. The coefficient of the term in the binomial expansion is nCk or n!/k!(n-k)!.
