Jude has to simplify the parenthesis first then multiply. She didn't follow PEMDAS
Answer:
- 2x² + 7x + 1
Step-by-step explanation:
f(x) - g(x)
= x² + 2x - 6 - (3x² - 5x - 7) ← distribute parenthesis by - 1
= x² + 2x - 6 - 3x² + 5x + 7 ← collect like terms
= - 2x² + 7x + 1
Answer:
Brooke
Step-by-step explanation:
We can solve this by figuring out how far each person runs a second
Stephanie runs 12 feet a second so nothing needs to be done here
Liz runs 306 feet in 38 seconds. To solve for the distance ran in 1 second we can divide (306/38)= around 8 feet
Will runes 1 mile in 491 seconds. A quick search will tell use that 1 mile is equal to 5280 feet and 5280/491 = 10.75
Brooke runs 851 feet in 1 minute or 60 seconds. 851/60 =14.18
Brooke obviously runs the furthest in one second and therefore she's the fastest runner
Answer:
2.150 = 2.15
2 +15/10 > 2.15
2 + 0.015 < 2.15
215/100 = 2.15
Step-by-step explanation:
2.150 = 2.15, because 2.15 can be rewritten as 2.150.
2 +15/10=2+1.5=3.5
2 +15/10 > 2.15
3.5 > 2.15
2 + 0.015 < 2.15
2.015 < 2.15
215/100 = 2.15
2.15 = 2.15
