Answer:

3n+6\geq 12

Step-by-step explanation:

Given :The sum of three times a number and 6 is at least 12.

To Find:Write an inequality for the given statement

Solution:

Let n be the number

So, 3 times of a number = 3n

Now Sum of three times of a number and 6 = 3n+6

Since we are given that the sum of three times a number and 6 is at least 12(i.e. equal to or greater than 12)

So, A.T.Q.

3n+6\geq 12

Thus an inequality for the given statement: the sum of three times a number and 6 is at least 12 is 3n+6\geq 12

Answer:

x = 5

Step-by-step explanation:

Given that, exterior angles on the same side of a traversal are supplementary a Hence, sums up to 180°

Given the angles:

7x° + 11x° + 90° = 180°

18x° + 90° = 180°

18x° = 180° - 90°

18x° = 90°

x = 90° ÷ 18

x = 5

Please help me with this one.

Answer:

Step-by-step explanation:

Jackie   you should know that  the supplemental angles always add to 180°  :)

That's like angles  1 & 2  or   55° & 1  .  both are supplemental and add to 180°

Knowing this should make answering this pretty easy. :)

180 = ∠1 + 55

125 = ∠1

∠3 =∠1

∠2 = 55°

since line g is parallel to f , we know all the angles in the same places of line f are identical... got it?

Which of the following is equivalent to the polynomial given below?
Marizza181 [45]

Answer:

(x+(3+\sqrt{11}i)) (x+(3-\sqrt{11}i))

Step-by-step explanation:

The first step to this problem is to look at the key features of the initial expression given to us. Namely, the middle term.

Notice that it is just +6x. This indicates that the square root terms cancel out, meaning that their signs need to be opposite, but the threes need to have the same, positive sign. This indicates that our answer is option C, but you should always double check by multiplying the expression out to confirm. Here are the steps:

(x+(3+\sqrt{11}i)) (x+(3-\sqrt{11}i))

x^{2} +(3+\sqrt{11}i)x+(3-\sqrt{11}i)x+(3+\sqrt{11}i)(3-\sqrt{11}i)x^{2}+3x+\sqrt{11}ix+3x-\sqrt{11}ix+9+3\sqrt{11}i-3\sqrt{11}i-(\sqrt{11})^{2}(i^{2})x^{2}+6x+9-(11)(-1)

x^{2}+6x+9+11

x^{2}+6x+20

Therefore as we suspected, the answer is C.
