Step-by-step explanation:
let the numbers x and y
so x + y =13
x - y = 5
add two equations together
2x = 18
divide both side by 2
x = 9
sub in any equation
9 + y =13
y = 4
the numbers are 9 and 4
Step-by-step explanation:
as the denominator (x+3) is in both you need only one denominator to be multiplied in first rational number .
<u>2</u><u>x</u><u> </u><u>(</u><u>x-2</u><u>)</u><u>. </u><u> </u><u> </u>+ <u>5</u><u>. </u><u> </u><u> </u><u> </u><u> </u><u> </u>
(x+3) (x-2). (x+3) (x-2)
<u>2</u><u>x</u><u>^</u><u>2</u><u>-</u><u>4</u><u>x</u><u> </u><u>+</u><u>5</u><u> </u>
<u>(</u>x+3) (x-2)
it's cannot be solved after that.
To find surface area of 3D objects, you have to know the area formulas for basic shapes. For example, the area of a circle is

and the area of a rectangle is length times width. To find surface area of a cylinder, you will need to know both of those formulas, since the 3D shape involves both circles and rectangles.
Answer:
3

maybe??? or 12 ........
2*27= 54 which is an even number, not a perfect square, odd or prime. The prime factorization would be 2*3^3
B, Even
