First, we need to simplify your quadratic equation, in the form of ax^2-bx-c=0. Your equation turns out to be x^2-4x+5=0
To find your solutions, x1+x2=-b/a or 4 in this case, and x1*x2=c/a or 5 in this case. So we need to find two numbers when added together is 4 and multiplied together to get 5. We can easily find our roots by using the roots formula, or (-b (+/-)sqrt(b^2-4ac))/2a. When plugging everything in, we have (4(+/-)sqrt(16-20)/2. As you can make out from the plugged in equation, you can't have a negative number under the radical symbol in order for it to be true.
Your answer is C, no real solutions.
Hope this helps.

Answer:

Angl.(QMT) = 134°

Angl.(QMT) = Angl.(QMS)+ Angl.(SMT)

or, 134°= (7x-4)° + (2x+3)°

or, 134° = 7x + 2x -4° +3°

or, 134° = 9x -1°

or, 134° + 1° = 9x

or, 135° = 9x

or, 135°/9° = x

or, 45° = x

x=45°

Vladimir79 [104]

Answer:

The fraction of tiles that will be the color of "sand" is 23/60

Step-by-step explanation:

we know that

The sum of the fractions of the tiles must be equal to 1

Let

x ----> the fraction of tiles that will be the color of "sand"

we have that

\frac{1}{4}+\frac{1}{6}+\frac{1}{5}+x=1

solve for x

Find the Least Common Multiple of denominators

LCM=(2^2)((3)(5)=60

Multiply both sides by 60

\frac{60}{4}+\frac{60}{6}+\frac{60}{5}+60x=60

simplify

15+10+12+60x=60

60x=60-37\\60x=23\\x=\frac{23}{60}

therefore

The fraction of tiles that will be the color of "sand" is 23/60
