The side opposite the angle 19 degrees is given by 15sin 19 = 4.9 units, while the side adjacent the angle 19 degrees is given by 15cos 19 = 14.2 units.
Answer:
3(2x + 3y)
Step-by-step explanation:
Here, we want to divide
The inner term of the first part can be splitted by the use of the difference of two squares
That is;
given two perfect squares, separated by negative; we can write the factors as;
a^2-b^2 = (a-b)(a + b)
Thus;
4x^2 - 9y^2 = (2x-3y)(2x + 3y)
matching term for term;
6x/2x will give 3
while (2x-3y)(2x + 3y)/(2x-3y) = 2x + 3y
So we have the results of the division as;
3(2x + 3y)
Answer:
x+5= x+5 7.5=7.5 and 2x-5= 2x-5
