Answer:

No real solutions.

B is correct

Step-by-step explanation:

Given: 3x^2+x+10=0

We are given a quadratic equation and need to solve for x.

Quadratic formula: ax^2+bx+c=0

x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

For our equation, a=3, b=1 and c=10

Substitute the value of a, b and c into formula

x=\dfrac{-1\pm\sqrt{1^2-4\cdot 3\cdot 10}}{2\cdot 3}

x=\dfrac{-1\pm\sqrt{-119}}{6}

Here, Roots are imaginary because number inside the square root is negative.

Hence, No real solutions.

a group 5 friends want to buy a flat screen tv for $ 210. the tax comes to $15. write and solve a multiplication equation to fin
Greeley [361]

Let x be the amount each friend pays .

There are five friends contributing ,so 5x will be the total money collected .

It needs to equal the price plus the tax, 210 + 15 = 225

So the equation becomes,

5x = 210 + 15

5x = 225

dividing right side by 5, we have

x = 225/5 = 45

Answer: So each frien pays $45.
