Answer:

The number to add is (11/2)^2 = 121/4

Step-by-step explanation:

Here, we want to know the number that will complete the square

We rewrite the equation as follows;

x^2 + 11x = -30

x^2 + 11x + (11/2)^2 = -30 + (11/2)^2

x^2 + 11x + 121/4 = -30 + 121/4

PLEASE HURRY WILL MARK BRAINIEST THIS IS AN EASY QUESTION
viva [34]

first qn

4/36=1/9

total no. of ways to roll a dice=36

no. of ways to produce 7=3

(1+6=7, 2+5=7, 3+4=7)

no. of ways to produce 11=1

(5+6=11)

there are 4 ways in total. 4/36 simplify it to be 1/9

second qn im not sure but i think its

1/9 x 50 = 50/9 = 5 x (5/9)

round it off to the smaller whole no. which is 5 so i think its 5 times in 50 trials

The polynomial 3x2 is a with a degree of .
ZanzabumX [31]

To determine the degree of a polynomial, you look at every term:

  • if the term involves only one variable, the degree of that term is the exponent of the variable
  • if the term involves more than one variable, the degree of that term is the sum of the exponents of the variables.

So, for example, the degree of 7x^{55} is 55, while the degree of xy^2z^4 is 1+2+4 = 7

Finally, the term of the degree of the polynomial is the highest degree among its terms.

So, 3x^2 is a degree 2 polynomial (although it only has one term)

similarly, x^2y + 3xy^2 + 1 is a degree 3 polynomial: the first two terms have degree 3, because they have exponents 2 and 1.
