Find the value of c that makes the trinomial a perfect square.
x²+26x+c

c = 169

Step-by-step explanation:

To make the trinomial a perfect square

add ( half the coefficient of the x- term )², that is

x² + 2(13)x + 13²

= x² + 26x + 169

= (x + 13)² ← a perfect square

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

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.
