18/81 = 10/X
cross multiply
18*X =81*10
18x =810
divide both side by the coefficient of X which is 18
18x /18 = 810 /18
X= 45
I hope this helps you
2x-3=x+2
X=5
HG=11x+5=11.5+5=60
JI=60/2=30
If no repeats, there are 8×7×6×5×4×3×2×1=40320.
Answer:
3pf² - 21p²f + 6pf - 42p²
= 3pf² + 6pf - 21p²f - 42p²
= 3pf(f +2) - 21p²(f + 2)
= (3pf - 21p²)(f +0 2)
Answer: (3pf - 21p²)(f + 2)
