Thank you, this helps so much have a good life.

Each cube is  128/2 = 64 cm³

^{x * x * x = 64}   

^{x^3 = 64             x = 4 cm side length}

l x w = area

4/(4+3) =  4/7      4/7 x = l

3/(4+3)  = 3/7      3/7 x = w

4/7 x  * 3/7 x = 588

12 /49 x^2 = 588

x = 49                                     4/7 (49) = l = .......... in          3/7  (49) = w = .........  in

interest per quarter in decimal form =  .05/4

after ONE quarter (3 months)

    400 ( 1 + .05/4) =  $ ............

100%   -   D  - R  =  Indep

100 - 36 -36   =   28% indep

.28 x   =    1400 voters

x = total voters = 1400/ .28 =..............

100% -  18% = 82 %  =   'the remaining calls'

82  * .08 =   6.56%  of calls makes a sale

2x²-7x+3=0​

(2x      ) ( x        )    = 0

(2x -1)(x-3)  = 0  

2x-1 = 0      x-3 = 0

  x = 1/2        x = 3

sin(α − β) = sin α cos β − cos α sin β

                = sinx cos pi   -  cos x sin pi

                = -sin x   (-1)     -   cos (x)  ( 0)

                = - sin x

Acute angle means Q I    so both sin and cos are +

sin²  + cos² =1       then cos = sqrt ( 1 - (8/17)^2)    = 15/17   

 cot  = cos / sin      .........     you can finish

tysm!

The area of one of the triangles are: $\frac{1}{2}(7 - 4)(8) = \frac{1}{2}(24) = 12$ 

This means the area of both triangles is double that, which is 24 inch².

The area of the bottom rectangle is 16 x 4 = 64 inch².

Add the two areas up and you get 64 + 24 = 88 inch²

Angle ∠CDB is just 180 - 120 = 60 degrees. 
Since the total degree of the angles in a triangle are 180^o, we can write an equation:

60 + (22x + 4) + (15x + 5) = 180
60 + 4 + 5 + 22x + 15x = 180
69 + 37x = 180

37x = 111

x = 3

3x - 5 >= 4x - 3

-2 >= x

So, -1 doesn't work. 

In some cases, you can just test them individually. 

I hope this helped. :))

=^._.^=

64+ 56 = 120

15x+5+60+22x+4=180

37x+69 = 180

37x = 111

x=3

91 seems to be the shortes way    10+10+13+8+11+16+23=91

                                                        or

                                                       13+8+11+16+23+10+10=91

its not 60 ;-;

*** corrected  ***

Had an incorrect '+' sign:

and   at  -2          x-5   has to equal 2x-b

                            x-5 = 2x-b

                            b - 5 = x                for x = -2

                             b - 5 = -2

                             b = 3
