Insert parentheses in the expression 6 + 10 x 2 so that the expression equals 32

(6+10) × 2

Step-by-step explanation:

If we insert parentheses there...

(6+10)=16,

16×2 equals 32,

therefore, we insert parentheses around the 6 and 10

(6+10)×2

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.
