Please help me solve this. Also please provide working out.

A=238.87 cm

Step-by-step explanation:

First find the area for the rectangle

11*23= 253 cm

then find the area for the little circles

D=3cm so r=1.5cm

Now plug in values into formula

A=π(1.5)^2

A=π(2.25)

A=3.14(2.25)=7.065cm

A=7.065cm since there are two circles

7.065*2=14.13

Now subtract the area of the circles from the rectangle

253-14.13=238.87

(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
