To create a square trinomial on the left side of the equation, find a value that is equal to the square of half of.
Answer:
<u>4</u>( -1 <u>-11 </u>)+2 (<u>17</u>)
<u>-14</u>
Step-by-step explanation:
This one requires more abstract thinking than you'd expect!
So essentially you want to count up how many -11's there are, -1's and 17's.
There are four -11's and four -1's, and two 17's.
So that means 4 x -11 + 4x-1 + 2x17 = The Total Sum of Subscribers
We can "factor out" a 4 from the -11 and -1.
4( -1 - 11) + 2(17)
So then you'd solve that and get
<u>-14</u>
Answer:
x = 6
Step-by-step explanation:
Since, ∠1 ≅ ∠2
By angle bisector theorem,
By substituting the measures of each side in the given ratio of the sides,
12 = x(x - 4)
12 = x² - 4x
x² - 4x - 12 = 0
x² - 6x + 2x - 12 = 0
x( x - 6) + 2(x - 6) = 0
(x + 2)(x - 6) = 0
x = -2, 6
Since, measure of the sides can't be negative, x can not be negative.
Therefore, x = 6 will be the answer.
Hello from MrBillDoesMath!
Answer:
The first choice (with the square roots of negative integers)
Discussion:
Number such as 0,1,2,3 or -4, -5, -8, or Pi, sqrt(12), sqrt(15), or 1/2, 1/10, 1/14 are all REAL numbers.
The square root of a negative number, such as sqrt(-3), is an imaginary number. The answer is the first choice
Thank you,
