Answer:

10 and 2

Step-by-step explanation:

a + b = 12

a - b = 8

let 'a' = 8 + b

substitute:

8 + b + b = 12

2b + 8 = 12

2b = 4

b = 2

a must be 10 then

Answer:

x = 15

Step-by-step explanation:

Assuming you require the value of x

The product of the external part and the whole of one secant is equal to the external part and the whole of the other secant, that is

9(9 + x) = 8(8 + 19), that is

81 + 9x = 8 × 27 = 216 ( subtract 81 from both sides )

9x = 135 ( divide both sides by 9 )

x = 15

The function g is defined by g(x)=3x² – 6.<br> Find g (2x)<br> 8(2x) = 0

Pepsi [2]

g(2x) is $g(2x)=12x^2-6$

Step-by-step explanation:

We are given $g(x)=3x^2-6$

We need to find g(2x)

Solving:

$g(x)=3x^2-6\\g(2x)=3(2x)^2-6\\g(2x)=3(4x^2)-6\\g(2x)=12x^2-6$

So, g(2x) is $g(2x)=12x^2-6$
