The answer is D. The action taken between each number is multiplying by 3. With this question, I'd say an easy way to answer it is to look at each answer given (in this case 36 and 108) and see if it fits the sequence with the given values (12 and 324).

Andrew has a salary of £250. He shares his salary with his sister in the ratio 2:3 every week. He saves 12% each week. How many

exis [7]

A = Andrew
S = Sister

A : S
2 : 3
2 + 3 = 5
250 ÷ 5 = 50
2 × 50 = 100
3 × 50 = 150

∴ A : S
100 : 150
So Andrew keeps £100 of his salary every week.

Of this, he saves 12%:
100 × (12 ÷ 100) = 12
So he saves £12 every week

360 ÷ 12 = 30
∴ it will take him 30 weeks to save £360.

Solve the equation by completing the square. 2x-18x+58=0

lubasha [3.4K]

$x^{2} -18x+58=0$

We have got quadratic equation. We calculate it by using Δ.

$\Delta=(-18)^{2} -4*1*58=324-232=92>0$
$\sqrt{\Delta} = \sqrt{92} =2 \sqrt{23}$

$x_1= \frac{-b- \sqrt{\Delta} }{2a} = \frac{18-2 \sqrt{23} }{2} =9- \sqrt{23}$
∨
$x_2= \frac{-b+ \sqrt{\Delta} }{2a} = \frac{18+2 \sqrt{23} }{2} =9+ \sqrt{23}$

Hope it helps :)
