The answer is B.
Step-by-step explanation:
Given that the total angles in a triangle is 180° so in order to find the value of x, you have to substract 60° and 80° from 180° :
Answer:
18
Step-by-step explanation: 32/5.76
See how much 32 goes into 57
32 goes into 57: 1 time
1 times 32 is 32
32 - 57 is 25
Then bring down your 6 which now it will be 256
Now how much dose 256 go into 32
It would be 8: 8 x 32 is 256 - 256 = 0
So ur answer is 18
Answer:
Step-by-step explanation:
Each side of the square is s meters long.
By the Pythagorean Theorem,
length of diagonal = √(s²+s²) = √(2s²) = s√2 meters
s√2 = 11.3
s = 11.3/√2
perimeter = 4s = 45.2/√2 ≅ 31.96 meters
Hello from MrBillDoesMath!
Answer:
Case 1: x is a real number. In this case f(x) has no real solution.
Case 2: x is a complex number. In this case the roots of f(x) are
x = 3 +\- 2 sqrt(3) i
(sqrt = square root. "i" = sqrt(-1))
Discussion:
Add 1 to both sides of the given equation:
2(x-3)^2 -1 + 1 = -25 + 1 or
2(x-3)^2 + 0 = -24 or
2(x-3)^2 = -24 (*)
Case 1: x is a real number. In that case as the square (x-3)^2 is always >0, so (*) has no real solution.
Case 2. x is a complex number ( a + bi, where a <> 0). In this case divide both sides of (*) by 2,
(x-3)^2 = -24/2 = -12 =>
x-3 = +\- sqrt(-12) = +\- sqrt (12 * -1) = +\- sqrt (4 * 3 * -1) = +\- 2 sqrt(3) * i
where i = sqrt (-1).
Add 3 to both sides gives
x = 3 +\- 2 sqrt(3) i
Thank you,
