Answer:

\sqrt{80}

80 is the number in the square root

Step-by-step explanation:

d = \sqrt{(x_{2}-x_{1}  )^{2} +(y_{2}-y_{1}  )^{2} } \\d = \sqrt{(4-(-4)  )^{2} +(5- 1 )^{2} }\\d = \sqrt{(4+4  )^{2} +4^{2}\\d = \sqrt{8^{2} +4^{2} }\\d=\sqrt{64 +16}\\d=\sqrt{80}

Olenka [21]

Answer:

6 * 3/4 = 9 2 = 412 = 4.5

Step-by-ste

6 * 3/4 = 6/1  3*4 = 18/4 = 9/2

2 · 2 = 9/2

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(18, 4) = 2. In the next intermediate step cancelling by a common factor of 2 gives 9

2

.

In words - six multiplied by three quarters = nine halfs.

Consider the quadratic equation. x^2=4x-5. How many solutions does the equation have?
Vesna [10]

x^2=4x-5
subtract 4x from both sides
x^2-4x=-5
add 5 to both sides
x^2-4x+5=0

input into quadratic formula which is x=\frac{-b+ \sqrt{b^2-4ac} }{2a} or \frac{-b- \sqrt{b^2-4ac} }{2a}

si ax^2+bx+c
so a=1
b=-4
c=5
input
\frac{-(-4)+ \sqrt{-4^2-4(1)(5)} }{2(1)}=\frac{4+ \sqrt{16-20} }{2(1)}=\frac{4+ \sqrt{-4} }{2}=\frac{4+ \sqrt{4} times \sqrt{-1} }{2} \frac{4+2 times  \sqrt{-1}  }{2}=  \frac{6 times  \sqrt{-1}  }{2}=3 times  \sqrt{-1} [\tex][\tex]\sqrt{-1} representeds by 'i' so solution is 3i

then if other way around then wyou would do
\frac{-(-4)- \sqrt{-4^2-4(1)(5)} }{2(1)}=\frac{4- \sqrt{16-20} }{2(1)}= \frac{4- \sqrt{-4} }{2} =\frac{4- \sqrt{4} times \sqrt{-1} }{2}= \frac{4-2 times \sqrt{-1} }{2}=\frac{2 \sqrt{-1} }{2}= \sqrt{-1} and [\tex]\sqrt{-1} [/tex] is represented by i


the solution is x=3i or i (i=\sqrt{-1})
but i is not real, it is imaginary so there are no real solution so the answer is C
