The measures of the sides of a triangle are 56, 90, and 106. use the pythagorean theorem to classify the triangle as acute, obtuse, or right.

Ineed to know the answer to this algebra question.

The width of a rectangle is 20 units. can the perimeter p of the rectangle be 64 units when its length x is 11 units? no, because p = 2x + 2(20) no, because p ≠ 2x + 2(20) yes, because p ≠ 2x + 2(20) yes, because p = 2x + 2(20)

Which of the following is the explicit rule for a geometric sequence defined a recursive formula of a -5a for which the first term is 23?
