Answer:
Step-by-step explanation:
1)It should be (-4)
2) It should be (-6) Not (-2)
3) It should be 30x²
4) It should be xyz
5) It should be 
6) 16x²
7) 
8) 
9)
10) a² + b² +2ab
11) -9
12)x² - x + 0
Answer:
x = 0.3 (see below)
Find the x intercept/zero.
To find x intercept/zero, subsitute H (x) = 0.
0 = 5.7 - 19x
Move the variable to the left hand side and change the symbol.
19x = 5.7
Now, divide both sides.
x = 0.3
Solution is 0.3
Alternate solution is x = 3/10.

Answer:
Area of the parallelogram =base×height
area of parallelogram =3cm×2cm
area of parallelogram = 6cm²
Plug in -3n as n into the functon K(n)=4n+5
so you get
K(-3n)=4(-3n)+5
K(-3n)=-12n+5
