40x^2 + 150
30x^2 + 250

What does x have to be in order for the expressions to equal?

the answe i =−n+5

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.

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
