Alexxx [7]

Answer:

$\dfrac{-15}{8}$

Step-by-step explanation:

<h3>Fraction division:</h3>

$\sf \dfrac{3}{4} \ \div \dfrac{-2}{5}$

Use KCF method.

Keep the first fraction.
Change division to multiplication
Flip the second fraction.

$\sf \dfrac{3}{4} \ \div \dfrac{-2}{5}=\dfrac{3}{4}*\dfrac{-5}{2}$

$\sf = \dfrac{3*(-5)}{4*2}\\\\ =\dfrac{-15}{8}$

Answer:

y^2 +8y + 16

Step-by-step explanation:

6y^2 +2y +5 - (5y^2 -6y -11)

I distribute the minus sign

6y^2 +2y +5 - 5y^2 +6y +11

Then I put them vertical.

6y^2 +2y +5

-5y^2 +6y +11

------------------------

y^2 +8y + 16

This is in standard from since the exponential decreases.

Answer:

704 cm

Step-by-step explanation:

The two triangles are 8x12=96 and since there are two triangles 96x2=192.

Next you do the top and bottom rectangles 10x16=160 and the two rectangles are the same size so 160x2=320.

Now you do the middle rectangle 16x12=192.

Now you add all the areas together 192+320=512+192=704cm.

So the answer is 704 cm!
