3+5x or 5x+3, because when it is 3 more, it is saying add 3, and when it is saying 5 times, it is saying multiply by 5, so your expression would be 5x+3
All you have to do it <span>Identify the legs and the hypotenuse of the triangle. You know that the triangle is a right triangle since the ground and the raised portion of the porch are perpendicular—this means you can use the Pythagorean Theorem to solve this problem. Identify a, </span>b<span>, and c. Use the Pythagorean Theorem to find the </span>length<span> of c.</span>
Answer:
8( 3x+2y) ( 9x^2 -6xy +4y^2)
Step-by-step explanation:
216x^3 + 64y^3
Factor out the greatest common factor of 8
8( 27x^3 +8y^3)
Rewriting
8 ( (3x)^3 + (2y)^2))
Recognizing this as the difference of cubes)
a^3 + b^3 = (a+b) (a^2-ab+b^2)
8 ( (3x)^3 + (2y)^2)) = 8( 3x+2y) ( 9x^2 -(3x)(2y) +4y^2)
=8( 3x+2y) ( 9x^2 -6xy +4y^2)
The expression is not factorable with rational numbers.
By using a coordinate system I believe you can find the position of any objects on a flat surface.
If you have an eraser on your table and would like to know its position, you could make your own x and y axis and see in which quadrant your object is in.
your eraser could be 2 units in the x direction (horizontal) and 5 units in the y direction (vertical).
Now you can use this 'x and y' axis that you have drawn to locate any object.
If you want to be accurate, you should draw your axes with a meter ruler and choose your point of origin.
Hope I answered your question.
