Answers

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

If the factored form is given by

$(3x-4)(x+2)$

Then its standard form will be given by

$(3x-4)(x+2)\n\n=3x^2+6x-4x+8\n\n=3x^2+2x+8$

if factored form is given by

$(3x+2)(x+4)$

Then its standard form will be given by

$(3x+2)(x+4)\n\n=3x^2+12x+2x+8\n\n=3x^2+14x+8$

Hence, only first option is correct.

Answer:

Factored form: (3x-4)(x+2)

Standard form: 3x^2+2x-8

Step-by-step explanation:

3x(x+2)-4(x+2)=(3x-4)(x+2)

3x(x+2)-4(x+2)=(3x^2+6x)-(4x+8)

=3x^2+6x-4x-8

=3x^2+2x-8

PLS ANSWER QUICKLY

Answers

Answer:

3.195

Step-by-step explanation:

Answer:

To solve this equation, you need to multiply each term separately and then add them up.

3 × 1 = 3 1 × 1/10 = 1/10 9 × 1/100 = 9/100 5 × 1/1000 = 5/1000

Now we can add them all together:

3 + 1/10 + 9/100 + 5/1000 = 3 + 0.1 + 0.09 + 0.005

Simplifying the decimals, we get:

3 + 0.1 + 0.09 + 0.005 = 3.1 + 0.09 + 0.005

Adding the decimals gives:

3.1 + 0.09 + 0.005 = 3.195

Therefore, the solution to the equation is 3.195.

What is the equation of the line in slope-intercept form?

Answers

Answer:

y = 4/3x + 4

Step-by-step explanation:

y = mx + b is the formula for finding the slope intercept form equation

m = slope

b = y intercept

If you look at points (-3, 0) and (0, 4), you can calculate the slope

You have to go over, from point (-3, 0), 3 times, and up four to get to the point (0, 4)

Slope is change in y over change in x, so, if we look to see where the line crosses the y-axis, or vertical axis, we can see it reach the number four on the y-axis, b = 4

Now, lets create your equation...

y = 4/3x + 4
