We have 4(k-6)-(3k+2)=-5 and the answer is k=21
        
                    
             
        
        
        
Area of a rectangle is the product of length times width.  Thus, here we need the product of 8 1/2 inches by 11 inches.
One way of doing this follows:            8.5
                                                         8.5
                                                       ----------         
                                                         93.5 square inches
Rounding up, this comes out to 94 square inches.
Alternatively:     17             187
                         ---- * 11 = ------- = 93.5 square inches; rounded, that's 94.

Hello,
2x^3+14x^2+6x+42=2x^2(x+7)+6(x+7)
=(x+7)(2x²+6)
=2(x+7)(x²+3)  in IR.
or In C  2(x+7)(x-i√3)(x+i√3)
        
             
        
        
        
I’m a little confused do you have a picture I could solve for cos then
        
             
        
        
        
Answer:
B and D
Step-by-step explanation:
To find the percentage, you divide Martin's correct answers by the total number of questions, then multiply the result by 100.
To find the fraction, it's <em>correct answers/total questions</em>.
