The simplest way to do this is to use the formula where

$\frac{y(2)-y(1)}{x(2)-x(1)}$

is equal to slope.

(2--6)/(4--2)= 8/6.

Hope this helps!

3.4^2-2.2^2×4.6-3.5×10.5 would be the simplified expression.

Note that ^ is an exponential sign.

Hope it helped,

Happy homework!

Answer:

14 7/12

Step-by-step explanation:

You take 6 3/4 and subtract 1/2 cup, which equals 6 1/4. Then you take 6 1/4 and divide that by 3. Then you multiply that answer (2 1/12) by seven.

$y=(2x+3)^2 = 4x^2 +12x +9$

Taking 4 out from first two terms, we will get

$y=4(x^2+3x)+9$

Now we divide the coefficient of x by 2 and add and subtract the square of the result, we will get

$y=4(x^2+3x+\frac{9}{4}-\frac{9}{4})+9$

Distributing 4

$y=4(x+\frac{3}{2})^2+9-9$

Cancelling 9

$y=4(x+\frac{3}{2})^2$

And that's the required standard form.
