The number is -13.
In order to find this, we first need to make each part of the statement into a mathematical statement.
Twice the difference of a number and 2.
2(x - 2)
Three times the sum of the number and 3
3(x + 3)
Now we can set them equal to each other and solve.
2(x - 2) = 3(x + 3) ----> Distribute
2x - 4 = 3x + 9 ------> Subtract 2x from both sides
-4 = x + 9 -----> Subtract 9 from both sides
-13 = x
Answer:
it's D
Step-by-step explanation:
i just know what I am talking about
Answer:
Step-by-step explanation:
There isn't one. The first term is x^4.
The other two are stated in terms of k. There is nothing common here.
You can do 2 of the three. Terms 2 and 3 have a common factor of 4k, so what you can get is
x^4 - 4k(k^2 - 1)
Answer:
B.) why Factor p+ 12r - 6, I did not do that below.
Step-by-step explanation:
r^2+12r-6=0
solve:
r^2 + 12 r + 36 - 36 - 6 = 0
factor the trinomial by completing the square.
( r + 6)^2 -42 = 0
(r + 6)^2 = 42
r + 6 = root(42 ) or r + 6 = - root(42)
r = -6 + root(42) or r = -6 -root(42)
Answer:
decrease
Step-by-step explanation:
the percent change measures FROM the first value. A change from 50 to 75 is a change of 50% (25 is the difference between the two numbers, and 25 is 50% of 50). A change from 75 to 50 is a change of -33.3% (25 is still the difference between the two. 25 is 33.3% of 75
