Answer:  The correct option is (C) 2 + 3y.  

Step-by-step explanation: We are given to select the expression that is a factor of the following expression :

E=3xy+2x-18y-12.

To select the correct factor, first we need to factorize the given expression.

The factorization is as follows :

E\\\\=3xy+2x-18y-12\\\\=x(3y+2)-6(3y+2)\\\\=(x-6)(3y+2)\\\\=(x-6)(2+3y).

Thus, the required factors of the given expression are (x - 6) and (3y + 2).

The correct option is (C) 2 + 3y.

Which equation is true?
enot [183]
Lets solve all of these:-

#1

√361 = 361 · 2
         
         ?
√361 = 361 · 2
√361 = 19
361 · 2 = 722

19 ≠ 722
So this equation is not true

#2:-

√361 = 19²

         ?
√361 = 19²
√361= 19
19² = 19 · 19 = 361

19 ≠ 361
So this equation is not true

√361 = 361 ÷ 2 

         ?
√361 = 361 ÷ 2 
√361 = 19
361 ÷ 2 = 180.5

√361 ≠ 361 ÷ 2 
So this equation is not true

√361 = √19²
√361 = 19
√19² = 19

19 = 19

SO the last one is right. Hope I helped ya!! xD

Mr. Lopez asked kids from after school what there favorite dessert is. 15% voted for cinnamon twirls and 85% voted for jumbo coo
mafiozo [28]
85/15 is 5 2/3

so, to find 85% with 15%, you would multiply 12 (also 15%) by 5 2/3.

12*5 2/3=68.

you could also find it using the 1% method:

1% of 15 is .15.
.15*85=68.

Hope this helps!
