Semmy [17]

Answer:

143degrees

Step-by-step explanation:

sum of angles of a triangle =180degrees

let the third unknown angle be x

99+37+x=180

136+x=180

x=180-136

x=44

the sum of two opposite interior angles is equal to the exterior angle

44+99=<PQR

<PQR=143 degrees.

OR

the sum of angles on a straight line is 180 degrees

<PQR+37=180

<PQR=180-37

<PQR=143

Can (5z+3)(-5z-3) result in a difference of squares
castortr0y [4]

Answer:

no, it cannot

Step-by-step explanation:

a difference of square is: a² - b² = (a - b)(a + b)

looking at the expression (5z+3)(-5z-3), we see that it does not fit the criteria of the breakdown of a perfect square, as (-5z-3) has a negative <em>a</em> term (-5z)

if we FOILed (5z+3)(-5z-3) out, we would get:

-25z² - 30z - 9, which is not a difference of squares
