Which is the completely factored form of 12x3 – 60x2 + 4x – 20?

Answers

Answer 1

Answer: $12x^3 - 60x^2 + 4x - 20 \n \n GCF = 4 \n \n 4( (12x^3)/(4) + (-60x^2)/(4) + (4x)/(4) - (20)/(4)) \n \n 4(3x^3 - 15x^2 + x - 5) \n \n 4(3x^2(x - 5) + (x - 5)) \n \n 4(x - 5)(3x^2 + 1) \n \n$

The final result is: 4(x - 5)(3x² + 1).

Using the helpful saying
Please (parentheses)
Excuse (exponents)
My (multiply)
Dear (divide)
Aunt (add)
Sally (subtract)

We can see that multiplying comes first in this equation, then dividing then adding so
2x3=6
then
28/7=4
then
6+4=10

324 is the same as the sum of 144 and v

Answers

Answer:

v = 180

Step-by-step explanation:

324 = 144 + v

v = 324 - 144

v = 180

Answer:

v = 180

Step-by-step explanation:

The equation is basically 324 = 144 + v

Then you just solve the equation:

324 = 144 + v

-144 = -144

180 = v

Solve using substitution.
4a=3b+3
a=b-1

Answers

4(b-1)=3b+3
4b-4=3b+3 -- subtract 3b from both sides
b-4=3 -- add 4 to both sides

b=7
Substitute b into equation 2
a=b-1
a=7-1

a=6

Verify:
4(6)=3(7)+3
24=21+3
24=24 -- True.

4a=3b+3
Put a=b-1 in the above equation
4(b-1) = 3b+3
open the brackets
4b - 4 = 3b + 3
collect B-terms together on one side
4b - 3b = 3+4
b = 7
