Answer:

  \overline{\text{BC}}=\boxed{28}

Step-by-step explanation:

The marked angles are congruent, so their opposite sides are congruent.

  2x +7 = 4x -7

  14 = 2x . . . . . . . add 7-2x

  28 = 4x . . . . . .  multiply by 2 to find 4x

The length of BC is 28.

A plot of 1/no2 versus time is linear. using this information, identify the factor by which the rate will increase in model (c)
WITCHER [35]
This is hard in mathematical language, but there is only this way to present it. Let us denote by A the consentration of the substance and by A' its rate.
We have that b/A= t+c where c is a constant.
Hence A=b/(c+t)
By differentiating, we get that A'=-b/(C+t)^2
Then, we have that -(A)^2=A'/b
Hence at any point, we have that if we make the concentration 17 times, we have that there is a 17 times bigger , the rate will become bigger by 17*17, hence 289 times faster.
