A. f(x) = 4x

B. f(x) = 4 – x

C. f(x) = x – 4

D. f(x) = x + 4

Atriangle has sides with lengths of 10 yards, 13 yards, and 18 yards. is it a right triangle?

In a certain pentagon, the interior angles are a, b,c, d,e where a, b,c, d,e are integers strictly less than 180. ("strictly less than 180" means they are "less than and not equal to" 180.) if the median of the interior angles is 61 and there is only one mode, then what are the degree measures of all five angles?

Aright triangle has an area of 18 square inches. b: if the triangle is not an isosceles triangle, what are all the possible lengths of the legs, if the lengths are whole numbers. answer !
