x^2 = -25
there is a solution if you know imaginary numbers
if you do not stop now and say no solution
else
take the square root
x = sqrt (-25)
x =sqrt(-1) sqrt(25)
x=+- 5i
x = 5i, -5i
x^2 =18
take the square root of each side
x =+-sqrt(18)
x=+- sqrt(9)sqrt(2)
x=+- 3sqrt(2)
x=3sqrt(2), -3sqrt(2)
The value of x is given by the pythagoras theorem
X^2 = 17^2 - 15^2
X^2 = 289-225
X^2 = 64
X = sqrt64
X= 8cm
Answer:
C and X , B and L , A and W , D and G are congruent
Answer:
(5,12)
Step-by-step explanation:
Ratio total =5+6=11
Difference between points
x-x axis from A to B=0-11=-11
y-y axis from A to B=22-0=22
Points from B=6/11(-11,22)=(-6,12)
Point M=Point B+(-6,12)=(11-6, 0+12)=(5,12)
60 students. You take the total students, 300, and multiply by 20% as a decimal, .2. 300 x .2 = 60.
