Answer:
m = - 3
Step-by-step explanation:
a³ + 27 ← is a sum of cubes and factors in general as
a³ + b³ = (a + b)(a² - ab + b²), thus
a³ + 27
= a³ + 3³
= (a + 3)(a² - 3a + 9)
comparing a² - 3a + 9 to a² + ma + 9, then
m = - 3
Answer:
A=20,000 m2 per year
Step-by-step explanation:
we have that Volume (V) =300,000 m3, so V=A*h, where A=area (m2) and h=15m
V=A*h ⇒ 300,000m3=A*15m ⇒ A=300,000m3/15m ⇒ A=20,000 m2
Multiply every coordinate by the scale factor 3
(-1,2,0) ----> (-3,6,0) is the answer
Answer:

Step-by-step explanation:
Since the line goes through the origin and is propotinal, we just do y/x
4/3= 1 1/3
y=1 1/3x
