Answer:
(?) = (x-5)
Step-by-step explanation:
Use difference of squares:

Answer:
Smaller Number = 10
Larger Number = 33
Step-by-step explanation:
Let the smaller number be "x" and the larger number be "y"
5 TIMES smaller is SUBTRACTED from TWICE larger, the result is 16, we can write:
2y - 5x = 16
and
Larger increased by 3 TIMES SMALLER, result is 63, so we can write:
y + 3x = 63
We can write this in terms of x, as:
y = 63 - 3x
Now we put this in equation 1 and solve for x first:
2y - 5x = 16

Now,
y = 63 - 3x
y = 63 - 3(10)
y = 63 - 30
y = 33
Smaller Number = 10
Larger Number = 33
We use this formula to calculate the sum of all interior angles of a regular polygon; 180(n-2) , n= number of sides
so 180(5-2) = 540
each interior angle = 540 ÷ 5 = 108
UMM IS there a diagram you want me for me......
