Answer:
Your answer is 62 square inches
Step-by-step explanation:
You can cross off 1 & 2, as they are too small.
Lets split this up.
(2*3)+(2*3)+(3*5)+(3*5)+(2*5)+(2*5)
2*3 + 2*3 = 12
3*5 + 3*5 = 30
2*5 + 2*5 = 20
30+20+12 = 62
The cubes that are listed would be
1, 8, 27, 64, 125, 216, 343, 512, 729, 1000
Devon finished first, because it took his 6.0999 seconds to race down the street. Tasha came in second, with 6.168 seconds. Liza got third place, because she finished the race in 6.188 seconds. Finally, in last place is Evan, who finished in 6.20 seconds.
I came to this by comparing place values. As you can see, I put the times in order from first to last.
6.0999 seconds
6.1680 seconds
6.1880 seconds
6.2000 seconds
Hope this helps :)
Answer:
d. 18a² - 12a
Step-by-step explanation:
f(x) = 2x² + 4x
f(-3a) = 2(-3a)² + 4(-3a)
2(-3a)² + 4(-3a)
2(9a²) + (-12a)
18a² - 12a
