There are 400 fish in a large tank. Write a numeric expression to find the number of fish in the tank if the number of fish increases by 23%. Juan says the expression is 1.23(400); Calista says it’s 400 + 0.23; and Angelo says it’s (1 + 0.23)(400). Are they all correct? Explain why each expression is correct or incorrect.

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0

it would more likely be bald eagle because its has more in the box so about 75%.

14

step-by-step explanation:

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
