                  Hello!

✧・゚: *✧・゚:*    *:・゚✧*:・゚✧

❖ The unknown number is 6.

15 - 9 = 6

To find the value of the second expression you can subtract 9 from both sides:

9 - 9 = 0

15 - 9 = 6

Therefore, ? = 6.

Answer:

Q 12 roots of the equation

2x^{2} -6+1=0 \\= (x-\frac{\sqrt{10} }{2})(x+\frac{\sqrt{10} }{2})\\

∝ = \frac{\sqrt{10} }{2}

β = -\frac{\sqrt{10} }{2}

no matter if u oppose the root

(i) 2(\frac{\sqrt{10} }{2})(-\frac{\sqrt{10} }{2} )^{2}+2(\frac{\sqrt{10} }{2} )^{2}(-\frac{\sqrt{10} }{2})+2(

(ii)((\frac{\sqrt{10} }{2})^{2} - 3 (\frac{\sqrt{10} }{2})(-\frac{\sqrt{10} }{2}) + ((-\frac{\sqrt{10} }{2})^{2}) = \frac{25}{2}

Q 13  roots of equation

4x^{2} -3x-4=0\\\alpha = -0.693\\\beta = 1.443

the roots of the second equation are

x1 = 1/3(-0.693) = -0.231

x2 = 1/3(1.443) = 0.481

the equation is

(x+0.231)(x-0.481)=0

x^{2}-\frac{1}{4} x-\frac{1}{9}

Using Pythagoras in the first question
c=\sqrt{16 ^{2} + 4^{2} } =16.4924
which is approximately 16.5
for the second question
we also use Pythagoras
b^2=c^2-a^2
\sqrt{13^{2}-12^2}=5

Levart [38]
The formula is A=p(1 + (r/n))^(nt)
A = 3500(1 + (.08/4))^(4*2)
