tankabanditka [31]

Answer:

The correct answer option is C. 13.6 units.

Step-by-step explanation:

Line segment AB was dilated to create the line segment A'B' using the dilation rule $D_{Q, 0.15}$ .

We are to find the value of $x$ which is the distance between the twp points A and A'.

For this, we will divide the distance of A'Q by the dilation factor and then subtract the given length.

$\frac{2.4}{0.15} = 16$

x = $16-2.4$ = 13.6 units

Answer:

$4p^{2} +6p-8$

Step-by-step explanation:

Remember these rules for addition, substraction, multiplication or division:

Addition

+ + = +

- - = -

Big + number - = +

Big -number + = -

Substraction

change the sign!

And follow the rules for addition

Multiplication or division

+ + = +

- - = +

+ - = -

Now for the exercise

$2p^{2} + 3p - 4$

- ( $- 2p^{2} -3p +4$ )

Change the signal

$2p^{2} + 3p - 4$

( $+2p^{2}+3p-4$ )

$4p^{2} + 6p -8$
