How do you prove that a2 - 6a plus 9 is a perfect square?
a2 - 6a + 9 = a2 - 3a - 3a + 9 = a(a - 3) - 3(a - 3) = (a - 3)*(a - 3) = (a - 3)2
How do you factor quadratic equation a2 12a plus 27?
a2 + 12a + 27 = (a + 3)(a + 9)
What is the correct formula for adding the values in cells A1 A2 A3?
The simplest and best way is: =A1+A2 You could also do it any of the following ways: =SUM(A1:A2) =SUM(A1,A2) =SUM(A1+A2) =SUBTOTAL(9,A1,A2)
A squared - a - 72?
a2 - a - 72 = (a - 9)(a + 8)
What is 5a3-45a equals -2a2 plus 18?
5a3-45a=-2a2+18 5a(a2-9)=-2(a2-9) 5a=-2 a=-2/5
How do you factor a2 plus 6a-27?
(a + 9)(a - 3)
What is a factor of a2 81?
(a + 9)(a - 9)
Is 9 bigger than 4.9?
Yes, 9 is bigger than 4.9 is.
Which is bigger 4.2 kilograms or 9 kilograms?
9 kilograms is bigger than 4.2 kilograms because 9 is bigger than 4.2
How many matrix multiplications required to compute matrix raise to the power n?
At most n-1. However, it can be a lot fewer. For example, calculating A10 does not require 9 multiplications. A*A = A2 A2*A2 = A4 A4*A4 = A8 A8*A2 = A10 Only 4 multiplications were required.
What is the formula to find sum of cells a1 a2 and a3?
There following two options should work:=sum(A1:A3) or=A1+A2+A3
What is the value of d in the arithmetic sequence -6 -1 4 9?
Here a1 = -6, a2 = -1, a3 = 4 & a4 = 9 d = a2-a1 = -1-(-6) = -1+6 = 5 d = a3-a2 = 4-(-1) = 4+1 = 5 d = a4-a3 = 9-4 = 5 Therefore the common difference d = 5
