  148.92 square inches

Step-by-step explanation:

A = 1/2bh

  = (1/2)(20.4 in)(14.6 in) = 148.92 in²

The area is half the product of the base length and height. The height is measured perpendicular to the base. As here, the point to which height is measured need not be above any portion of the base.

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."
