Answer:
x=123 degree
Step-by-step explanation:
sum of angles in a straight line=180 degree
angle one=57 degree
second angle=x
hence,x+57=180
x=180-57
<u>x</u><u>=</u><u>1</u><u>2</u><u>3</u><u> </u><u>degree</u>
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:
1 inch = 8 miles
112÷14=8, so one inch is 8 miles.
