Answer:
70 km in an hour
Step-by-step explanation:
35 x 2 is 70
Answer:
- 4x² - 8x - 3
Step-by-step explanation:
We want to calculate
1 - (2x + 2)² ← expand using FOIL
= 1 - (4x² + 8x + 4) ← distribute parenthesis by - 1
= 1 - 4x² - 8x - 4 ← collect like terms
= - 4x² - 8x - 3
Answer:
u = 4/5
Step-by-step explanation:
Expand
2u - 2 - 6 = 20u - 20 - 3u
Rearrange with like terms on either side
12 = 15u
u = 4/5
