#1 simplify. (this is square roots) 36/121 answers: a. 18/11 b. 18/10 c. 6/121 d. 6/11
#2 simplify 162 a. 81 and 2 b. 9 and 18 c. 9 and 6 d. 9 and 2
#3 between what 2 consecutive intergers does 85 lie? answers: a. 8 and 9 b. 10 and 11 c. 84 and 85 d. 9 and 10

No.1 is D. 6/11

No.2 is B. 9 and 18

No.3 I think it is C. 84 and 85.

I hope this helps!

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

(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
