1. How much greater is -20x^2+5x+17 than -19x^2+20x+18
ehidna [41]

Answer:

1. -x²-15x-1

2. -33x⁷+10x⁶-14x⁵+4x⁴+11x²-5x+32

Step-by-step explanation:

-20x^2+5x+17 - (-19x^2+20x+18)

-20x² + 19x² + 5x - 20x + 17 - 18

-x² - 15x - 1

-20x^7+10x^6-5x+15 - (13x^7+14x^5-4x^4-11x^2-17)

-20x⁷ - 13x⁷ + 10x⁶ - 14x⁵ + 4x⁴ + 11x² - 5x + 15 + 17

-33x⁷ + 10x⁶ - 14x⁵ + 4x⁴ + 11x² - 5x + 32

Which equation is related to the given equation? column a column b 1. 61 + 18 = z 2. z = 61 – 18 3. –18 = 61 – z 4. 18 = 61 – z
Fofino [41]

Question 1.).

Column A.):  

Answer ==>  z  =  61  –   18, is Related to  z  +  18   =  61,   ==>   z    =   43

Answer: ===>  18   =    61    -  z,  is Related to  z    +   18   =  61,   ===>   z   =   43

z      +     18     =   61

Let's solve your equation step-by-step.

z     +     18      =     61

Step 1: Subtract 18 from both sides.

z  +   18   −   18    =     61    −     18

z     =     43

Graph:  ========>   z    +    18     =     61  =========>     z     =======>    43

Column (A),     Answer:     =======>     z     =      43



Question 2.).  

Column. B.):  

Answer: =====>   61 + 18   =   z,  Related to z  - 18  =  61  ====>  z   =   79 Answer: ===>   –18   =   61   –   z,  Related to   z  -   18   =  61  ====>  z  =  79    

z      -     18     =     61

Let's solve your equation step-by-step.

z         −       18        =           61

Step 1: Add 18 to both sides.

z     −     18     +     18     =     61       +        18

z    =       79

   Answer     z     =      79




Therefore, The answers to your Equation: Column (A),/Column (B)

Question 1.).

Column A.):  

Answer ==>  z  =  61  –   18, is Related to  z  +  18   =  61,   ==>   z    =   43

Answer: ===>  18   =    61    -  z,  is Related to  z    +   18   =  61,   ===>   z   =   43



Question 2.).  

Column. B.):  

Answer: =====>   61 + 18   =   z,  Related to z  - 18  =  61  ====>  z   =   79 Answer: ===>   –18   =   61   –   z,  Related to   z  -   18   =  61  ====>  z  =  79  





Hope that helps!!!!!!!!                            : )
