A triangle has side lengths of (9.2b+8.7) centimeters, (3.2b−2.5) centimeters, and (9.8c+1.6) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?

Parabolas y=−2x^2 and y=2x^2 +k intersect at points a and b that are in the third and the fourth quadrants respectively. find k if length of the segment ab is 5.

*let m∠cob = 50°30’, m∠aob = 70° and m∠aoc = 20°30’. could point c be in the interior of ∠aob? why? a. point c could be the interior of aob but it is not the only case b. point c is the interior of aob c. point c is not the interior of aob d. the given is not possible for the plane geometry answer

The area of the map is the product of the length and width. write and expression for the area as the product of the two binomials do not multiply
