2. for the following arithmetical sequence, determine a1 and d and find an explicit formula for the sequence: -8, -5, -2, 1… a. what is a1? b. what is the common difference d? c. write an explicit formula for an using the formula for arithmetical sequences an = a1 + (n – 1)d.

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

image result for what is another name for consecutive interior angles? ​

when two lines are crossed by another line (called the transversal): the pairs of angles on one side of the transversal but inside the two lines are called consecutive interior angles. in this example, these are consecutive interior angles: d and f.
