Q4. The cost of two pens and three highlighter is Rs 705. If the pen costs Rs 40 more than the highlighter, find the cost of the pen and the highlighter.

Rs 290

Step-by-step explanation:

705-(40x2)=625

625÷5=125

125+40=165

165+125=290

Hope this helps! Thanks.

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0

i believe it is b and c. (side note, i got the same computer from k-12 lol i’m in 8th grade and this is my first year, will it get
