Answer:
Angle 8 = 100 degrees
Step-by-step explanation:
Angle 2 = Angle 8
Because, they are alternate exterior angles.
Pretty sure it is 3 units
Step-by-step explanation:
Find two points on the line.
20 is a multiple of both 4 and 5, so the points (5, 0) and (0, 4) are on the line.
Click those two points and you have your line!
To find the perimeter you have to add all sides.
36 + 36 + 36 + 36 = 144
The perimeter of the square is C. 144 inches
Hope this helps. :)
Answer:
All the answers are given below.
Step-by-step explanation:
(i) (x+3)(x-3) =x² -3² =x² -9 {Since (a+b)(a-b) =a² -b²}
(ii) (x²-3)(x²+3) =(x²)² -3² =
{Since (a+b)(a-b) =a² -b²}
(iii) 
(iv) (x-3)(x²-9)(x+3) =(x²-9)(x²-9)=(x²-9)²=
{Since, (a-b)² =a²-2ab+b²}
(v) (x²+y²)(x²-y²) = (x²)² -(y²)² =
(vi) (x²+y²)² =
{Since (a+b)² =a²+2ab+b²}
(vii) (x-y)²(x+y)² =(x²-y²)² =
{Since (a-b)² =a²-2ab+b² and (a+b)(a-b) =a²-b²}
(viii) (x-y)²(x²+y²)²(x+y)² =(x²+y²)²(x²-y²)² =
