Kate multiplied two binomials using the distributive property. she made a mistake in one of the steps. where did she first make a mistake? (x – 2)(3x + 4)

1. (x – 2)(3x) + (x – 2)(4)
2. (x)(3x) + (2)(3x) + (x)(4) + (2)(4)
3. 3x2 + 6x + 4x + 8
4. 3x2 + 10x + 8

A. Step 2
B. Step 3
C. Step 4

A. Step 2

Step-by-step explanation:

She did not include the negative signs on step 2.

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
