Answer:
x³ - 2x² - 3x + 36
Step-by-step explanation:
(x + 3)(x² - 5x + 12)
Each term in the second factor is multiplied by each term in the first factor , that is
x(x² - 5x + 12) + 3(x² - 5x + 12) ← distribute parenthesis
= x³ - 5x² + 12x + 3x² - 15x + 36 ← collect like terms
= x³ - 2x² - 3x + 36
Answer:
x = 3
Step-by-step explanation:
Once again we want to use the relationship stated earlier
Where A * B = C * D
Once again imagine that the segments in the given problem have letters
A = x
B = 12
C = x + 1
D = 9
Now we create an equation using the relationship
12 * x = 9(x+1)
now we solve using basic algebra
step 1 distribute the 9 to the x and the 1
9 * x = 9x
9 * 1 = 9
now we have 12x = 9x + 9
step 2 subtract 9x from each side
12x - 9x = 3x
9x - 9x cancels out
now we have 3x = 9
step 3 divide each side by 3
3x/3=x
9/3=3
we're left with x = 3
Answer:
14 min
Step-by-step explanation:
Dividing 840 seconds by (60 sec / 1 min) results in 14 minutes.
( (60 sec / 1 min) is a conversion factor, sec to min or min to sec.)
15x-6
=3*(5x-2)
The final answer is 3*(5x-2).
Hope this helps~
42 because you take 46 and add 42 it will be 88 and the one sister is still 2 years older
