2(24 + 9) + 2(15 - 8)
Remember in Maths ; do inside the brackets first !!!!
2(33) + 2(7)
You can either factor '2' or multiply '2' to each set of brackets.
Factor ;
2(33 + 7) =>
2(40 ) = 80
or
Multiply '2' to each set of brackets
2(33) + 2(7) =>
66 + 14 = 80 As before. !!!!

What is the center and radius of the circle with equation (x plus 9)2 (y plus 5)2 64?
(x + 9)^2 + ( y + 5)^2 = 64 = 8^2 This is in the Pythagorean form of a^2 + b^2 = r^2 The displacement of 'x' is '-9' and the displacement of 'y' is '-5' Hence the centre as ( x,y) is (-9, -5) The radius is 'r at '8 units'.
What is the 10th term of the sequence of n plus 3?
The sequence n plus 3 can be represented as 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, ... The 10th term of this sequence can be found by substituting n = 10 into the formula, which gives us 10 + 3 = 13. Therefore, the 10th term of the sequence is 13.
