3x 2 + 12 x = 0

Me ayudan :u y si no saben mejor ni comenten:)

Answers

Answer 1

Answer: 3x + 2 + 12x = 0
15x + 2 = 0
15x + 2 - 2 = 0 - 2
15x = -2
15x/15 = -2/15
X = -2/15
I hope that answers your question

I used 8 bags of sand for 12m squared . How much will I need for 15m squared?

Answers

12m divided by 8 bags = 1.5 bags per m

So 1.5 bags times 15m = 22.5 bags o'sand

12 divided by 8 = 1.5

15 divided by 1.5 = 10

the answer is 10

What is the quotient (x3 + 3x2 + 5x + 3) ÷ (x + 1)?x2 + 4x + 9
x2 + 2x
x2 + 2x + 3
x2 + 3x + 8

Answers

Answer: The correct option is (C) $x^2+2x+3.$

Step-by-step explanation: We are given to find the quotient by dividing the following :

$Q=(x^3+3x^2+5x+3)/(x+1).$

We will try to factorize the numerator ad then divide by the denominator to find the quotient.

We have

$Q\n\n\n=(x^3+3x^2+5x+3)/(x+1)\n\n\n=(x^2(x+1)+2x(x+1)+3(x+1))/(x+1)\n\n\n=((x+1)(x^2+2x+3))/((x+1))\n\n=x^2+2x+3.$

Thus, the required quotient is $x^2+2x+3.$

Option (C) is correct.

Hello,

Answer C

x^3+3x²+5x+3=x^3+2x²+3x + x²+2x+3=x(x²+2x+3)+1(x²+2x+3)=(x²+2x+3)(x+1)

Find the product of (3.7 × 104) and 2

Answers

"769.6" I hope it helps

im assuming the "and 2" part means to also multiply so just multiply 3.7*104 to get 384.8. then multiply the product by 2 and the answer will be 769.6.

Final answer:

The solution to the given inequality, |2x + 1| ≤ 3, is the set { -2 ≤ x ≤ 1 }, which corresponds to answer choice (c). This is achieved by solving two separate inequalities, 2x + 1 ≤ 3 and - (2x + 1) ≤ 3.

Explanation:

The subject of the question is Mathematics, specifically a High School algebra topic on solving absolute inequalities. The student's question is asking us to solve the inequality |2x + 1| ≤ 3. To do this, we need to create and solve two separate inequalities: 2x + 1 ≤ 3 and - (2x + 1) ≤ 3.

Solving 2x + 1 ≤ 3 gives us 2x ≤ 2 and x ≤ 1 . Solving - (2x + 1) ≤ 3 gives us -2x - 1 ≤ 3 , then -2x ≤ 4 , and finally x ≥ -2 . Combining these answers gives us the solution set { -2 ≤ x ≤ 1 }, which corresponds to answer choice (c).
