Meghan tried to convince her class mate fiona that 2x+3=10 represents a expression. fiona disagrees and thinks that it represents a equation who is correct? (need now also show work )

Fiona is correct. Meghan is incorrect.

Step-by-step explanation:

An equation is a mathematical statement consisting of two sides and an equal sign equating those two sides. Each side comprises an expression. An equation is a statement because it claims the two expression equal. This may be true, or false, or true for only certain values of variable appearing in the expression. However, an equation is distinctly different from a simple expression.

m∠a is 90°

m∠b is 40°
