Answer:
(x+2) (x+6)
Step-by-step explanation:
x^2+8x+12
What 2 numbers multiply together to give you 12 and add together to give you 8
2*6 = 12
2+6 = 8
(x+2) (x+6)
Answer:
X=3
Step-by-step explanation:
11. x = 10, so DCE is 72. You get the measurement of x by adding 7x + 2 and x + 8 to equal 90. When you get x, you plug it in to the equation for DCE.
12. x = 17. KNM is 131. Get the measurement of x by adding both equations again, this time equaling it to 180 since it is a straight line and doesn't have a right angle. Plug in the x to the equation for KNM.
Answer:
A)(Always)Rational
B)(Always)Rational
C)(Sometimes)Rational
This is because Square roots are generally irrational(like the 
) and the product and difference of rational numbers should always be rational!
