Answer:

84:7 = 12:1 (B)

250:400 = 5:8 (V)

4:80 = 1:20 (G)

40:20 = 2:1 (N)

12:108 = 1:9 (E)

270:30 = 9:1 (U)

55:33 = 5:3 (D)

560:80 = 7:1 (S)

75:55 = 15:11 (A)

24:28 = 6:7 (I)

63:33 = 21:11 (Y)

1,000:100 = 10:1 (R)

20:340 = 1:17 (M)

10:30 = 1:3 (O)

44:11 = 4:1 (H)

Which would be the best method to use to solve the following equations? Explain your reasoning.

o-na [289]

A. square root property

$3x^2-192=0\\x^2-66=0\\x^2=66\\x= -\sqrt{66} or \sqrt{66}$

it has one value with x which is x^2 and it cn be easily solved without having to factorise, quadratic formula cant be used as it need ax^2+bx+c=0 format

B. factorising

$x^2-x-6=0\\x^2+2x-3x-6=0\\(x+2)(x-3)=0\\x+2=0 and x-3=0\\x= -2 \\x= 3$

i just felt like this was easier to factorise than the other 2 options left

C. Completing the square

$x^2-6x-7=0\\(x-3)^2=0\\x= -1\\x= 7$

same reason personal preference

D- Quadratic

$x^2-17x-7=0\\x=\frac{-(-17)+\sqrt{(-17)^2-4(1)(-7)} }{2(1)} \\x=\frac{-(-17)-\sqrt{(-17)^2-4(1)(-7)} }{2(1)}\\x=17.4\\x=-0.402$

the 17 kinda threw me off and i didnt wanna get on factorising or doing completing the square so quadratic formal
