Answer:

(2x - y )2 - (y + 2)2 = 4 (x - y - 1)

Step-by-step explanation:

$(2x -y) 2 - ( y + 2 ) 2 = (4x -2y) -(2y + 4) \\\\$

$= 4x - 2y -2y - 4\\\\=4x - 4y - 4\\\\=4(x-y-1)$

75^0 = 1
so if you use radian it is 0.841if you use degree it is 0.017
anyway we usually make an approximation of sin(1) to 1

Hello!

√28x³y³ is equal to $2xy\sqrt{7xy}$

We can find this solution through the following steps.

Rewriting the equation by factoring 4 from 28, factoring out x², and factoring out y²
We then can rewrite 4 as 2² in our equation, leaving us with $\sqrt{2^{2}*7*(x^{2}x)*y^{2}y }$
We will then move our x and 7, and rewrite $2^{2}*x^{2}* y^{2}$ as $(2xy)^{2}$
We can then pull the terms from the radical leaving us with $2xy\sqrt{7xy}$

I believe it would be 68 miles per hour! To find the unit rate here you would divide miles by hours, or 340 by 5, which would give you 68.
