Find a common factor for 3y^3+2y^2 and 6y^4+4y^3​
Anit [1.1K]

Answer:

3y + 2

Step-by-step explanation:

We want to find a common factor for

3 {y}^{3}  + 2 {y}^{2}

and

6 {y}^{4}  + 4 {y}^{3}

We factor each of them to get;

3 {y}^{3}  + 2 {y}^{2}  =  {y}^{2} (3y + 2)

and

6 {y}^{4}  + 4 {y}^{3}  = 2 {y}^{3} (3y + 2)

We can observe now that;

The factor common to both expression is

3y + 2

What is the measure of triangle X in degree
Anna11 [10]

Answer:

A.) 40°

Step-by-step explanation:

A triangle is equal to 180°

Angle X and Y has the same angle, so both have 70°.

So:

70° × 2= 140°

To find the degree of the last angle, subtract the known degree, which is 140°, from the overall degree, which is 180°.

So:

180° - 140°= 40°

Answer= 40°

I hope this helps! :)

Rachel plans to fence in an area 7 meters long by 7 meters wide for her dog to run
timurjin [86]
If you are looking for the area of that, the answer would be 49 meters squared since in area, it is always length times width. 7x7=49. that answer would be 49 meters squared

The point P could be located in quadrant I, quadrant IV and the x-axis

<h3>How to determine the quadrant?</h3>

The coordinate of point P is given as:

P = (a, b)

Where a is positive

When a is positive, then the likely locations of P are:

  • On the x-axis, when b = 0
  • In quadrant I, when b is positive
  • In quadrant IV, when b is negative

Hence, point P could be located in quadrant I, quadrant IV and the x-axis
