Answer:
x = 3 ±
Step-by-step explanation:
x² - 6x - 4 = 0 ( add 4 to both sides )
x² - 6x = 4
To complete the square
add ( half the coefficient of the x- term)² to both sides
x² + 2(- 3)x + 9 = 4 + 9
(x - 3)² = 13 ( take square root of both sides )
x - 3 = ± ( add 3 to both sides )
x = 3 ±
900,000+80,000+500+7 is 980,507
Percent decrease. 41%
percent change= (new-old)/old *100
= -41 % the negative means decreasing
Answer:
The length of the angle bisector of angle ∠A is 6.01.
Step-by-step explanation:
It is given that length of leg AC = 5 ft and the hypotenuse AB = 13 ft.
Using pythagoras theorem
Bisector divides the angle in two equal parts, therefore,
In triangle ACD.
Therefore the length of the angle bisector of angle ∠A is 6.01.
Answer:
So first, they remove the denominator of x times x, because multiplication cancels out division, so then you're left with
3/1 times x = 2193
3/1 just equals three, so you write it down as 3.
3x = 2193
To isolate 3x, you need to divide by 3.
x = 731
Hope this helped :)
