Multiply the first term in the left parentheses by each term in the right parentheses. Then multiply the second term in the left by each in the right. Do the same with the third term in the left parentheses.

=(6x3 - 3x2 + 5x + 9)(7x + 9)
=(6x3*7x)+(6x3*9)-(3x2*7x)-(3x2*9)+(5x*7x)+(5x*9)+(9*7x)+(9*9)

Start multiplying each set
Remember when multiplying exponents, you add them

=(42x4)+(54x3)-(21x3)-(27x2)+(35x2)+(45x)+(63x)+81

Combine any like terms

=42x4+(54x3-21x3)-(27x2+35x2)+(45x+63x)+81

=42x4+33x3+8x2+108x+81

The answer is
A) 42x4+33x3+8x2+108x+81

Hope this helps! :)

Given:

The data set is:

87, 84, 85, 85, 86, 90, 79, 82, 78, 76

To find:

The mode of the given data set.

Solution:

We have,

87, 84, 85, 85, 86, 90, 79, 82, 78, 76

Arrange the data values in the ascending order.

76, 78, 79, 82, 84, 85, 85, 86, 87, 90

We know that the mode of date set is the most frequency value of the data set.

From the above data set it is clear that the number 85 has the highest frequency 2.

Therefore, the mode of the data set is 85.

if you flip a coin 10 times, what is the best prediction​ possible for the number of times it will land on heads?

Proabably. 5 because if there is 2 sides on a coin then you should divide 10÷2 which is 5.

Find the measure of the missing value in the
kumpel [21]

Answer:

12.6

Step-by-step explanation:

The two left sides have lengths, so this allows you to establish the ratio of the lengths of the sides of the triangles,

left triangle : right triangle

ratio = 25 : 17.5

The bottom sides are also in the same ratio.

ratio = 18 : w

Write a proportion by setting the ratios equal and solve for w.

25/17.5 = 18/w

Cross multiply.

25w = 17.5 * 18

25w = 315

w = 12.6

Answer: 12.6
