The hypotenuse of a right angle triangle when squared is equal to the base squared plus the height squared and the formula is usually given as:- a2+b2 = c2 whereas a and b are the base and height respectively and c being the hypotenuse which is the largest side
The area of the base of a cylinder is: pi times radius squared
Area of a triangle = 1/2 * base * heightWe have,Area = 28 cm squared, base = 8cmthen,28 = 1/2 * 8 * h28 = 4*hh = 7cm
Area= 1/2 x base x height So, 40 squared= 1/2 x 20x h 40 squared= 10h 40/10=10h/10 4 = height
K
(2b - 5)(b + 7)
The base is 14.
Base area= pi x radius squared

Since 3b is a factor of 9b, it is automatically the GCF.
3A + 9B = 3(A + 3B)
9
2a + 3 - 9b - a - 7 Bring like terms together: = 2a - a - 9b + 3 - 7 Combine like terms: = a - 9b - 4
When the base is squared.
9b + 6 - 8 = -36 9b = -38 b = 4.2222222(repeating)
The simplified expression is -9a -9b.
