(4/2)^2*3.4*4
2^2*3.4*4
4*3.4*4
13.6*4
54.4
(4/2)^2*3.4*4
2^2*3.4*4
4*1.7*4
6.8*4
27.2
the answer is 54.4 or the answer is 27.2, i can't quite figure it out but those are my best guesses
Answer:
13x^8 + 4x^5 - 16x^2
Step-by-step explanation:
Standard form is just rearranging each group of numbers so that the group with the most exponents on the variables is at the beginning. So it's basically least to greatest but with exponents. Hope this helped!
Answer:
Step-by-step explanation:
If c = 8, then:
5c^(3)+982 => 5(8)^3 + 982 = 3542
and
2c^(4)−7c = c(2c^3 - 7) => 8(2*512 - 7) = 8(1017) = 8136
So the second expression has the greater value when c = 8.
Answer:
Yes, they will have enough.
Step-by-step explanation:
1. $499.00 + 7% = $533.93
2. $225 x 2 = $550
3. $550 - $533.93 = $16.07 left to spend
