Answer:

Option G is right.

Step-by-step explanation:

Given that 2x^2+6x =36

To find possible values of x, let us use factorisation method.

First divide the equation by 2, x^2+3x-18 =0

Factors are (x+6)(x-3)

Equate each factor to 0

x+6 =0 or x-3=0

x =-6 or 3

Hence values of x are -6 and 3.

Pavel [41]

Answer:

Mary = 24

Chau = 15

David = 48

Step-by-step explanation:

The formula is

Mary + Chau + David = 87

And we know that

Chau = Mary - 9

David = Mary * 2

So when we fill this in

Mary + Mary - 9 + Mary * 2 = 87

4Mary - 9 = 87

4Mary = 96

Mary = 24

Chau = Mary - 9 = 15

David = Mary * 2 = 48
