Step-by-step explanation:

The expression is $x^3-2xy^2$ . To find the value, substitute the values x = 3 and y =-2 then follow order of operations.

$x^3-2xy^2\\3^3 -2(3)(-2)^2\\27 -2(3)(4)\\27 - 24\\3$

Hello,

In US, you don't know the sign "+"?

5-(x+5)>-2(x+4)
==>5-x-5>-2x-8
==>x>-8

If the length of a rectangular field is twice the width and the perimeter is 24. Write an equation that an be used to solve for

Sedbober [7]

If we use the width as x we have 2x with both widths and 4x with both lengths. So 6x=24 and x=4. So length is 8 and width is 4.

Find the products (3a-2)^2

Hi there ! \(๑╹◡╹๑)ﾉ♬

Answer: $\blue{ \boxed{ \bf {9a}^{2} - 12a + 4 } }$

Step-by-step explanation:

$\bf (3a - 2)^{2} =$

$\bf (3a - 2) \times (3a - 2) =$

$\bf 3a \times 3a - 3a \times 2 - 2 \times 3a - 2 \times ( - 2) =$

$\bf {9a}^{2} - 6a - 6a + 4 =$

$\red{ \boxed{ \bf {9a}^{2} - 12a + 4 } }$
