C.(2x + 5)(x + 1)
D.The polynomial is prime.

Answers

(2x + 1)(x + 3) = 2x^2 + 6x + x + 3 = 2x^2 + 7x + 3 A.

2x2 +7x +3
= 4+7x+3
= 7x +11

therefore, the polynomial is prime

Answers

Hello!

You are finding the probability that you will roll a number greater than 10

You do this by doing the amount of favorable outcomes over the total amount of outcomes

There are 2 numbers greater than 10

There are 12 total numbers

This is a probability of 2/12

2/12 = 0.17

The answer is A)0.17

Hope this helps!

Total number of possible outcomes = 12
Total number of favourable outcomes (i.e. greater than 10) = 2

P(greater than 10) = 2/12 = 0.17

Answer: 0.17

Determine whether the given point lies on the graph of the inequality. (-1,-3); -x-6y < 19.

in this case, is the point on the graph (yes or no)

Answers

-x - 6y < 19.

Point ( -1, -3) ⇔ x = -1 , y = -3
instead of the variables you need to put the values of x and y ( coordinates of the point )
- (-1) - 6*(-3) < 19

we calculate

1 + 18 < 19 record turns mushy

Proposal
the point does not belong to the graph

when added to the number that is produced by doubling the number x the result is equal to 8 times the number that is 5 less than x what is the value of x?

Answers

x is 4
4+4=8
4is less than 5

2x + x = 8(x-5)
3x = 8x-40
-5x = 40
x = -8

Just tell me if you need more assistance figuring out how I concluded that.

What is 3/11 to a percent?

Answers

when you divide 11 by 3, you receive a repeating decimal of .2727272727.
In order to convert this decimal into a percent, you must move the decimal point 2 units to the right. You should receive an answer of 27%.

3/11=0.272727/1
percent is parts out of 100
times 100/100
0.272727/1 times 100/100=27.2727/100=27.2727%
about 27%
