First find the secant line. The slope of the secant line through

(when

) and

(when

) is the average rate of change of

over the interval
![[-1,2]](https://tex.z-dn.net/?f=%5B-1%2C2%5D)
:

The tangent line to

will have a slope determined by the derivative:

Both the secant and tangent will have the same slope when

, or when

.
we have <D = (7x-1)° , <A =(5x+25)°
{ all angles of square is equal to 90° }
<A + <D = 180°
5x + 25 + 7x - 1 = 180°
12 x = 180 - 24
12x = 156
x = 13
<A = (5*13 +25) = 90
< D = ( 7*13-1) = 90
so ABCD is a square

Answer nica me ayudan a mi pliss...oh mana nose
Step-by-step explanation:
The correct answer for this question would be choice C) (5*2) + (5*7) or the third option since 5 * (2 + 7) and option C) both have the same solution which is 45, can both be classified as equivalent expressions.
