Those two functions just miss each other so there are no real solutions. Every polynomial with complex coefficients has complex solutions.

$2x^2 + 2 = 3x$

$2x^2 - 3x = -2$

$2( x^2 - \frac 3 2 x) = -2$

$x^2 - \frac 3 2 x = -1$

$x^2- \frac 3 2 x+ (\frac 3 4)^2= -1 + (\frac 3 4 )^2$

$(x - \frac 3 4)^2 = -\frac 7{16}$

$x - \frac 3 4 = \pm \sqrt{ -\frac 7{16}}$

$x = \frac 3 4 \pm \frac i 4 \sqrt{7}$

$x = \frac 1 4(3 \pm i \sqrt{7})$

Can a Scalene triangle be a isosceles triangle?<br><br> A: Always<br> B: Never<br> C: Sometimes

arsen [322]

A scalene triangle can never be an isosceles triangle. How? Well, let's take a look at the definition of a scalene triangle. In short, a scalene triangle is a classification of a triangle that does not have any congruent sides. On the other hand, an isosceles triangle is a triangle in which its legs are both congruent. Therefore, if a scalene triangle has two congruent legs, it wouldn't even be a scalene triangle, but instead it would be an isosceles triangle. Hope this helped!

three times a number is subtracted from another number and the difference is 3. The sum of the two numbers is 31. What is the sm

Aleksandr-060686 [28]

ANSWER

The smaller number is 7.

EXPLANATION

Let the numbers be x and y.

Then we have;

y-3x=3... eqn (1)

If the sum of the numbers is 3 then,

y+x=31... eqn (2)

Eqn(2) - Eqn (1)

x--3x=31-3

$4x = 28$

Divide both sides by 4,

$x = 7$

We put x=7 into the second equation,

y+7=31

y=31-7

y=24

The smaller of the two numbers is 7.
