4. Jose is doing his Algebra homework and comes to a problem that asks him to solve the equation 5x = 2x. He is unsure whether to divide
both sides by 2x or subtract 2x from each side. Will both methods
lead him to a correct solution or is one method correct and the other
incorrect? Explain your reasoning.

Use the following statements to write a compound statement for the conjunction or disjunction. then find its truth value. p: an isosceles triangle has two congruent sides. q: a right angle measures 90° r: four points are always coplanar. s: a decagon has 12 sides. a) a right angle measures 90° or an isosceles triangle has two congruent sides; true. b) a right angle measures 90° and an isosceles triangle has two congruent sides; true. c) a right angle measures 90° and an isosceles triangle does not have two congruent sides; false. d) a right angle measures 90° or an isosceles triangle does not have two congruent sides; true.
