Pls answer quick i will mark brainiest

see picture for a, 33.92  for b

Step-by-step explanation:

a net is like unfolded. since the base is a square, put a square in the middle with triangles coming off of all sides

(see picture below)

surface area =  base area + triangle area * 4

base area = 4 * 4 = 16

triangle area = 4*2.24 / 2 = 4.48

total area = 16 + 4 * 4.48 = 33.92

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."

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
