Answer:
-4a²+4a³
Step-by-step explanation:
Factoring x2+5x-1
The first term is, x2 its coefficient is 1 .
The middle term is, +5x its coefficient is 5 .
The last term, "the constant", is -1
Step-1 : Multiply the coefficient of the first term by the constant 1 • -1 = -1
Step-2 : Find two factors of -1 whose sum equals the coefficient of the middle term, which is 5 .
-1 + 1 = 0
Conclusion : Trinomial can not be factored
Final result :
x2 + 5x - 1
This is what did but I not sure it's right?!
False, 24 x 10 x 90 = 21,600, 90 x 2,400 = 216,000
Answer:
Use the explantion to answer your question
Step-by-step explanation:
Amount he paid for first 20 shares
= $25 + (20 x $10.51)
= $25 + $210.20
= $235.20
Amount he paid for next 20 shares
= $25 + (20 x $8.93)
= $25 + $178.60
= $203.60
Thus, total amount paid
= $235.20 + $203.60
= $438.80
