Answer:

D: -2

Step-by-step explanation:

Let's time 2 on both sides.

Then the equation will be:

(3x+4)=x

3x+4=x

-x        -x

2x+4=0

-4       -4

2x=-4

x=-2

So the answer is D:-2.

Can you please answer this question

-12+(-66)+48 and how

Thanks in advance

Answers

Answer:

-30

Step-by-step explanation:

so we will write the -12 as it is then multiply the positive sign by the negative sign of the num 66 (bc there are paranthesis around the number) it will be - sign (example 2+(-6) is equal to -4 and because the negative sign over powers the positive sign) then we will write the +48 as it is so it will be -12-66+48 = -30 (answer is negative bc its the sign of the biggest number)

really hope this helped and good luck!

Guys I need help I’m gonna fail math

Answer:

125% correct

3/5 correct

2/3 correct

Step-by-step explanation:

Here, we want to pick the appropriate conversion from percentage to fraction:

To convert from percentage to fraction, we simply divide by 100

125% = 125/100 = 1.25 correct

30% = 30/100 = 0.3 not 0.03 wrong

1% = 1/100 = 0.01 not 0.001 wrong

60% = 60/100 = 3/5 correct

50% = 50/100 = 1/2 not 1/4 wrong

2/3 = 2/3 * 100 = 200/3 = 66.66667% correct

1. Which expression is a cubic polynomial?3x^2 - 1
x^3 - 1
x^2 - x + 3
3x^2 - x + 3

2.Which of the following binomials is a factor of x^3 + 4x^2 +x - 6?

3. If a polynomial equation p(x) = 0 has 3 + 4i as a solution, what other solutions must it have?

Answers

1. A cubic polynomial is a polynomial of degree 3 (the degree of a polynomial is the highest degree among al terms), then the cubic polynomial is x^3- 1.

2. The polynomial x^3 + 4x^2 +x - 6 has root x=1, then x^3 + 4x^2 +x - 6=(x-1)(x^2+5x+6)=(x-1)(x+2)(x+3).

3. If a polynomial equation p(x) = 0 has 3 + 4i as a solution and has real coefficients, then 3-4i is also a solution.



Answer:

1. x^3 - 1

2. P(x) = (x + 5)(x + 2)(x)

3. x + 2

4. 3 - 4i

9 is 60% of what number?

Answers

Lets say 9 is 60% of x
so 9/x= 60/100 or x= 100*9/60=15
so 9 is 60% of 15.
