<span>Corresponding sides are sides found in two object that are located on the same location. 149. Two figures are said to be congruent when they have the same shape and size or if one object is a mirror image of the other object. Thus, two triangles having the same corresponding side lengths would be considered as congruent shapes. The answer would be true.</span>
So lets add the common fractions 3/4+3/4+1/4+1/2=7/4+1/2=18/8, now the whole numbers 3+1+2+4+2=12, so 12 18/8 and simplify 14 2/8= 14 1/4 <span />
6m² + 6m - 9m²
Add like terms.
(6m² - 9m²) + 6m
-3m² + 6m
~Hope I helped!~
I will be glad to help you in the comments. I do need to know though, what is the class this is presented in? Is this algebra, or calculus? Depending on the class, we have different approaches.
