How do I do this problem

Mathematics
1 answer:
aliya0001 [1]4 years ago
7 0

Answer:


Step-by-step explanation:

It is really quite simple, there are going to be three answers you can get Homozygous Dominant (TT or two capitol letters), Heterozygous (Tt one capitol and one lower case, and Homozygous Recessive (tt or two lowercase letters). To find the specific genotype or phenotype, you look at the letters and compare them to the chart. For the punnett square, you use the two parents genotypes, and put one on each of two sides on the square and take one letter from each side of the square and put them together. The probability is just how many of each is that specific phenotype, but you will want to us either ratios or percents. I hope this is helpful.

I think its C, not sure
Alona [7]
Yes; you are correct.
___________________________________________________
The correct answer is:
___________________________________________________
Answer choice:  [C]:  " x³ − 9x² + 23x <span>− 12 " .
___________________________________________________
Note: (a </span>− b) (c − d + e) = ac − ad + ae − bc + bd − be ;
___________________________________________________
          (x − 4) (x² <span>− 5x + 3) = 

   x * x</span>² = x³ <span>− 

   x * 5x = 5x</span>² + 

   x * 3   = 3x <span>−

   4 * x</span>²  = 4x² <span>−

   -4 * 5x =  -20x +

   -4 * 3 =  -12; 
________________________________________
</span>          (x − 4) (x² − 5x + 3) = 

x³ − 5x² + 3x −4x² − (-20x) + (-12) ;

=  x³ − 5x² + 3x −4x² + 20x − 12 ;

= x³ − 5x² − 4x² + 3x + 20x − 12 ;

= x³ − 9x²  + 23x − 12 ;  which is:

What is the value of x in the equation 1/5x – 2/3y = 30, when y = 15?
lianna [129]

Answer:

x = 200

Step-by-step explanation:

1/5x – 2/3y = 30

substitute in y

1/5x - 2/3(15) = 30

multiply

1/5x - 10 = 30

isolate the variable

1/5x = 40

multiply each side by 5

x = 200

Please help me TwT<br> Please and Thank you!
Llana [10]

Answer:

Option C (None Of The Above)

Step-by-step explanation:

Given expression = -  (\frac{ - e}{ - f} )

Lets multiply the numerator and denominator by -1.

=  >  - ( \frac{ - e \times  - 1}{ - f \times  - 1} )

=  >  - ( \frac{e}{f} )

Now , lets open the brackets.

=  >  \frac{ - e}{f}

But as this expression is not there in the given options , the correct answer will be Option C.
