Answer:
x =20
Step-by-step explanation:
We can use proportions to solve
$240 320
----------- = ------------
15 x
Using cross products
240x = 320 * 15
240x =4800
Divide by 240 on each side
240x/240 = 4800/240
x =20
Hello!
I believe the answer is (3x^2 - 3x + 5) • (x + 1)
I hope it helps!
1/16 * 6 = 6/16 or reduced to 3/8
you have to expand this question to make it x
The factorial ! just means we multiply by every natural number less that the value so
6! =6×5×4×3×2×1= 720
for permutations we use the formula n!/(n-r)!
so we have 8!/(8-5)!=8!/3!=8×7×6×5×4
for combinations s we have n!/(n-r)!r!
so we have 12!/(12-4)!4!=12!/8!4!=12×11×10×9/4×3×2=11×10×9/2=99×5
