Factorise 3k+12 with explanation step by step

3(k+4)

Step-by-step explanation:

3k and 12 have a common factor of 3

factor 3 out of the two values

3(k+4)

you can check by multiplying everything in the brackets by 3

3xk =3k

3x4=12

sine

step-by-step explanation:

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
