Answer:
math
Step-by-step explanation:
X = 8 when y = 4 and z = 9, then k = x/(yz) = 8/(4*9) = 2/9. The equation is x = (2/9)yz. when x = 16 and y = 6, (2/9)*6*z = 16, solve the equation we get z = 12
Answer:
Because the first has () and the second doesn't so if u multiply the first one you will have to start with the () but if u answer the second u can start with anything

Answer:
Let's factor x2+3x−18
x2+3x−18
The middle number is 3 and the last number is -18.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 3
Multiply together to get -18
Can you think of the two numbers?
Try -3 and 6:
-3+6 = 3
-3*6 = -18
Fill in the blanks in
(x+_)(x+_)
with -3 and 6 to get...
(x-3)(x+6)
Answer:
(x−3)(x+6)
