2 miles = 1/2 hour (a whole hour is 60 mins so half of that is 30 mins) 1 mile = 15 mins (15 mins is half of 30 mins) so yes its true
Probably like ten maybe four
Answer:
5,50,500,5000,50000
Step-by-step explanation:
The first term is given
a1 =5
The second term is when n=2
a2 = 10 * a1 = 10 * 5 = 50
The third term is when n=3
a3 = 10 * a2 = 10 * 50 = 500
The fourth term is when n=4
a4 = 10 * a3 = 10 * 500 = 5000
The fifth term is when n=5
a5 = 10 * a4 = 10 * 5000 = 50000
Answer:
-2x² + 10x - 12
Step-by-step explanation:
Given the expression 2(5x+3)−2(x^2 −3)
Expand
2(5x+3)−2(x^2 −3)
= 2(5x)+2(3) -2(x²)-2(-3)
= 10x + 6 - 2x²+6
= 10x -2x²+12
Express in standard form
= -2x² + 10x - 12
