I'm not sure about the variable part, but 1/4 of 76 years old is 19 years old. You can say that 19x is a variable. x stands for whatever you want it to stand for. I hope this helps!

Find the sum of the squares of the roots of 3x^2 + 4x + 12 = 0

Contact [7]

Answer:

-56/9

Step-by-step explanation:

Let p and q be the roots of the equation.

So, here's how we're gonna work it out:

${p}^{2} + {q}^{2} = \\ {p}^{2} + {q}^{2} +2 pq - 2pq = \\ ( {p}^{2} +2pq + {q}^{2}) - 2pq = \\ {(p + q)}^{2} - 2pq$

Vieta's formulas give us the sum and the product of the roots of a quadratic equation. Using them we obtain:

p + q = -b / a = - 4 / 3
p × q = c / a = 12 / 3 = 4

${(p + q)}^{2} - 2pq = \\ {( - \frac{ 4}{3} )}^{2} - 2 \times 4 = \frac{16}{9 } - 8 = \\ \frac{16 - 72}{9} = - \frac{56}{9}$

Solve the linear equation 2x+2/4=189.5

seraphim [82]

Change 2/4 to 1/2
2x+1/2=189.5
Subtract 1/2 from both sides(1/2 = .5)
2x=189
Divide both sides by 2
2x/2 = x
189/2= 94.5
x=94.5
