Answer:
4d+2m+13
Step-by-step explanation:
Answer:
function is f(x) = x+6
and the missing outputs are 19, 24 and 27
The possibile answer is 10 ÷ 6 = 1.6
There would be 14 female and 7 male, so the total number of students is 21.
Answer:
(x+1)(x-1)(x+3)(x-3)
Step-by-step explanation:
x4-10x^2+9
Group expression so that the coefficients of the x^2 terms add up to +9.
= x^4 -9x^2 - x^2+9
match coefficients in both groups
= x^4 -9x^2 - (x^2-9)
factor each group
= x^2 (x^2-9) - 1(x^2-9)
now factor out the common factor (x^2-9)
= (x^2-1)(x^2-9)
Finally, factor each quadratic factor
= (x+1)(x-1)(x+3)(x-3)
