Answer 2

Answer:

a) 24

b) 244

Step-by-step explanation:

a) 4x - 6y

x = 3

y = -2

(4 * 3) - (6 * -2) = 12 - (-12)

= 12 + 12

= 24

Let's check

let x be x

y = -2

4x - (6 * -2) = 24

4x - (-12) = 24

4x + 12 = 24

4x = 24 - 12

4x = 12

x = 12/4

x = 3

Yes they r equal.

Hence, verified.

And our first answer 24 is correct

b) a = -6

b = 2

2a^2 + 5b^2 = (2 * 6)^2 + (5 * 2)^2

= 144 + 100

= 244

Let's check

let b be b

2a^2 + 5b^2 = 244

144 + 25b^2 = 244

25b^2 = 244 - 144

25b^2 = 100

b®2 = 100/25

b^2 = 4

b = √4

b = 2

Yes they r equal

Hence, verified

And our first answer 244 is correct
