Step-by-step explanation:
0.2x² − 0.8x = 1.6
Multiply both sides by 5.
x² − 4x = 8
Complete the square by adding 4 to both sides.
x² − 4x + 4 = 12
(x − 2)² = 12
x − 2 = ±√12
x = 2 ± √12
The positive solution is x = 2 + √12 ≈ 5.46.
Answer:
x = 2
Step-by-step explanation:
Given
1 + 4x = - 5 + 7x ( subtract 7x from both sides )
1 - 3x = - 5 ( subtract 1 from both sides )
- 3x = - 6 ( divide both sides by - 3 )
x = 2
Answer:
Width = 3x So,
Length = x 3w + w = 56/2 = 28
3x + x = 4x
56 / 4 = 14 w = 7
x = 14
14 x 3 = 42
Answer: 42 meters Answer: dimension- 7 meters
Answer: Amount after 5 years become $5937.60.
Step-by-step explanation:
Since we have given that
Principal amount = $5000
Time period = 5 years
Rate of interest for 3 years = 6%
Rate of interest for 2 years = 8%
so, Amount becomes
Hence, Amount after 5 years become $5937.60.
