Answer:
(2x - 3)(x - 2).
Step-by-step explanation:
Factor: 2x^2 - 7x + 6
Use the ac method to do this:
Multiply the leading coefficient by the last term:
2 * 6 = 12.
Now we want 2 numbers whose product is 12 and whose sum is -7.
That would be -3 and -4 so we write:
2x^2 -4x - 3x + 6
Now factor by grouping:
= 2x(x - 2) - 3(x -2)
(x - 2) is common to the 2 parts so we have:
(2x - 3)(x- 2).
The options are:
(A)
(B)
(C)t= a(f -v)
(D) t= v(f-a)
Answer:
(A)
Step-by-step explanation:
Given the equation f=V+at which represents the final velocity of an object(f) with an initial velocity, V and an acceleration rate, a, over time, t.
We are required to solve for an equivalent equation with t as the subject.
In f=V+at
To make t the subject
Step 1: Subtract v from both sides
f-v=v-v+at
at =f-v
Step 2: Divide both sides by a
The correct option is A.

Answer:
C. An Exponent
Step-by-step explanation:
It is C because the number being squared is called the base number. In this case the base number is x.
The exponent, the amount of times that the base number will be multiplying itself by is 2.
Therefore, in x^2, the 2 is the exponent.
Answer:
x = 2.519842
Step-by-step explanation:
x^3 + 2 = 18
Subtract 2 from both sides: x^3 + 2 - 2 = 18 - 2
x^3 = 16
Take cubic route: x = (16)^1/3
Your answer is x = 2.519842
