16 - 3k + 5 and k is 4, then
16 -12 + 5 = 9
assuming you mean (3k+4)^2 = 9k^2 + 24k + 16
plus For example: (+15) + (+1) = +16 or 16 But minus plus minus is equals to minus itself For example: (- 8) - (- 4) = - 4
Two plus 3 minus 2 times 1 squared plus 4 times 16 squared minus 4 times 2 is equal to 1,019.
18 + 12 + 0 - 4 - 10 = 16
16
(3k - 2)(3k - 2) or (3k - 2)2
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
The answer is: x^2 -16
9x^(2) + 16 DOES NOT factor. Remember ; two squared terms with a plus(+) between them DOES NOT factor However, two squared terms with a minus(-) between them DOES factor . Hence 9x^(2) + 16 = (3x)^2) + 4^(2) does NOT factor However, 9x^(2) - 16 = (3x)^2) - 4^(2) does factor to ( (3x - 4)(3x + 4) Note the two different signs.
9 - 20 / 4 + 16 = 9 - 5 + 16 = 20
k=4
