Question

If x= -2 and y= 12,then 2(3x3+2y2)=

Answer 1

Answer:

The value of expression 2(3x^3 + 2y^2) when x = -2 and y = 12 is 528

Step-by-step explanation:

To find the value of 2(3x^3 + 2y^2)

The expression is 2(3x^3+2y^2)

x = -2 and y = 12

Substitute the value of x and y in the above expression we get,

2[3(-2)^3 +2(12)^2] =  2[ (3 * (-8) ) + (2*144)]

= 2[-24 + 288] = 2 * 264 = 528

Therefore the value of expression 2(3x^3 + 2y^2) when x = -2 and y = 12 is 528

Answer 2

Answer:

$528$

Step-by-step explanation:

we have

$2(3x^{3} +2y^{2})$

For $x=-2, y=12$

substitute the value of x and the value of y in the expression

$2(3(-2^{3}) +2(12^{2}))$

$2(3(-8) +2(144))$

$2(-24 +288)$

$2(264)$

$528$
