Solve the inequality 3u+3(u+1)>2u+7 and write the solution in interval notation.
strojnjashka [21]

<u>Given</u>:

The given inequality is 3u+3(u+1)>2u+7

We need to determine the solution of the inequality in interval notation.

<u>Solution of the inequality:</u>

The solution of the inequality can be determined by simplifying the inequality.

Thus, we have,

3u+3u+3>2u+7

       6u+3>2u+7

Subtracting both sides by 3, we get;

6 u>2 u+4

Subtracting both sides by 2u, we have;

4 u>4

Dividing both sides by 4, we get;

u>1

Writing it in interval notation, we get;

(1, \infty)

Thus, the solution of the inequality is (1, \infty)

Factor this equation , I can’t comprehend it
ivolga24 [154]

Answer:

B) (2x + 3)(2x - 3)

Step-by-step explanation:

Use the FOIL method for each answer choice.

FOIL = First, Outside, Inside, Last

(2x)(2x) = 4x²

(2x)(-3) = -6x

(3)(2x) = 6x

(3)(-3) = -9

4x² -6x +6x  -9

Simplify. Combine like terms:

4x² (-6x + 6x) - 9

4x² - 9

4x² - 9 = 4x² - 9 ∴ B) (2x + 3)(2x - 3) is your answer

these polygons are similar. find the similar ratio. any help ? please? ( also how do I ask a question ok here without typing 20
NNADVOKAT [17]
Answer: Choice B) 3/5

==================================================

Explanation:

The smaller horizontal side is JM = 15
The larger horizontal side is NQ = 25

The ratio of these corresponding sides is: 
small/large = 15/25 = (5*3)/(5*5) = 3/5

----------------

Alternatively,

The smaller vertical side is ML = 18
The larger vertical side is QP = 30

The ratio of these corresponding sides is: 
small/large = 18/30 = (6*3)/(6*5) = 3/5

----------------

Either way, the answer is 3/5
