Answer:
3x + 3
Step-by-step explanation:
Answer:
(b) -m, m + 3
Step-by-step explanation:
x² − 3x − m(m + 3) = 0
x² − 3x = m(m + 3)
x² − 3x + 9/4 = m(m + 3) + 9/4
(x − 3/2)² = m(m + 3) + 9/4
(x − 3/2)² = m² + 3m + 9/4
(x − 3/2)² = (m + 3/2)²
x − 3/2 = ±(m + 3/2)
x − 3/2 = m + 3/2, -m − 3/2
x = m + 3, -m
Answer:
Half a pound.
Step-by-step explanation:
To find the number of pounds he ate, multiply the fractions.

He ate 1/2 a pound.
0.002%. Just take 0.6/300 and input into a calculator.
12:15 does not belong, since that is a ratio of 4:5, whilst the others are all 3:4.
