2x2-5x-3=0
Two solutions were found :
x = -1/2 = -0.500
x = 3
Step by step solution :
Step 1 :
Equation at the end of step 1 :
(2x2 - 5x) - 3 = 0
Step 2 :
Trying to factor by splitting the middle term
2.1 Factoring 2x2-5x-3
The first term is, 2x2 its coefficient is 2 .
The middle term is, -5x its coefficient is -5 .
The last term, "the constant", is -3
Step-1 : Multiply the coefficient of the first term by the constant 2 • -3 = -6
Step-2 : Find two factors of -6 whose sum equals the coefficient of the middle term, which is -5 .

<h2>Sine rule:</h2>
Law of sine:
![\sf \boxed{\bf \dfrac{a}{Sin \ A}=\dfrac{b}{Sin \ B}= \dfrac{c}{Sin \ C}}](https://tex.z-dn.net/?f=%5Csf%20%5Cboxed%7B%5Cbf%20%5Cdfrac%7Ba%7D%7BSin%20%5C%20A%7D%3D%5Cdfrac%7Bb%7D%7BSin%20%5C%20B%7D%3D%20%5Cdfrac%7Bc%7D%7BSin%20%5C%20C%7D%7D)
a = y
A = 31°
b = 17 mm
B = 117°
![\sf \dfrac{y}{Sin \ 31^\circ}=\dfrac{17}{Sin \ 117^\circ}\\\\](https://tex.z-dn.net/?f=%5Csf%20%5Cdfrac%7By%7D%7BSin%20%5C%2031%5E%5Ccirc%7D%3D%5Cdfrac%7B17%7D%7BSin%20%5C%20117%5E%5Ccirc%7D%5C%5C%5C%5C)

Answer:
The answer would be 30 minutes
Step-by-step explanation:
Find how many ties 12 can go into 10. (Divide 12 divided by 10=1.2)
Multiply 25 times 1.2 (30)
Your answer would be 30 minutes
