Equivalent expressions are:

6x-3(3x-3)

-3(x-3)

-6x+3(3+3x)-6x

Step-by-step explanation:

We have to simplify each expression for comparison

Expression 1:

$6x+18-3x-9\\= 3x+9$

Expression 2:

$6x-3(3x-3)\\= 6x-9x+9\\= -3x+9$

Expression 3:

$-3(x-3)\\= -3x+9$

Expression 4:

$-6x+3(3+3x)-6x\\= -6x+9+9x-6x\\= -3x+9$

Hence,

Equivalent expressions are:

6x-3(3x-3)

-3(x-3)

-6x+3(3+3x)-6x

Can you work out G and H for me please. preferably telling me how you did it aswell

Veronika [31]

Abd is a right angled triangle so by pythagoras we know
${g}^{2} = {11}^{2} + {13}^{2} \\ {g}^{2} = 290 \\ g = \sqrt{290} \: or \: g = 17.03cm$
and to calculate h we need to use the sine rule
$\frac{h}{ \sin(22) } = \frac{g}{ \sin(32) } \\ \frac{h}{ \sin(22) } = \frac{17.03}{ \sin(32) } \\ h = \frac{17.03}{ \sin(32) } \times \sin(22) \\ h = 12.04cm$
i hope this helps

The perimeter of a square is proportional to the length of its sides. This relationship can be expressed by the equation p=4s. W

stealth61 [152]

Constant of proportionality is the constant value of the two proportional quantities, in this problem p and s, where 4 is the factor of proportionality because it is constant or k.

In simple terms, p is in direct proportion to s wherein the increase or decrease in value of s results to the increase or decrease in value of p with 4 the only factor remaining unchanged.

In the above problem, the number 4 is derived from the word square. We all know that a square has 4 sides of equal lengths, therefore, the perimeter is equivalent to the product of 4 and its lenght.
