Snowcat [4.5K]
Since there is a 180 degrees in a straight line and we know that the intersection of one angle is 27 degrees we can can say 180 -27 = 153 degrees.  So the four angles would be 27, 27 153, 153

Select the statement that correctly describes the expression below
Kitty [74]

Answer:

B

Step-by-step explanation:

The equation is (2x+5)^2.

It can't be A because 2 is the multiplier for only x.

It can't be C because the square is outside of the equation.

It can't be D because again, the square is outside of the equation.

So the only thing left is B.

Hope this helped!

Find the value of Q in the following system so that the solution to the system
lisabon 2012 [21]

Answer:

<h2>Q = -6</h2>

Step-by-step explanation:

If the solution of the system of equations is {(x, y): x - y = 4} - infinitely many solutions, then this system is consistent and dependent.

x - 3y = 4            <em>multiply both sides by 2</em>

2x - 6y = 8

Therefore Q = -6
