Hey there! :)
Answer:
x = 5/2 and 3.
Step-by-step explanation:
Factor the equation. Find numbers that will sum up to -11 involving the coefficient of 2, and that multiply into 15.
2x² - 11x + 15 = 0
(2x - 5)(x - 3) = 0
Use the Zero Product Property to solve for the roots of this equation:
2x - 5 = 0
2x = 5
x = 5/2
----------
x - 3 = 0
x = 3.
Therefore, the two values of x that are roots of this equation are:
x = 5/2 and 3.
Answer:
x=22
Step-by-step explanation:
break it down:
55-11 = 44
so 44/2 = 22
therefore
x=22

Answer:
Side-Angle-Side similarity is what will tell you that ABD ≈AEC.
Step-by-step explanation:
Since ABE is isosceles, that means that AB=AE, and that angles B and E are equal. In the problem they tell you that BD is congruent to EC, so you have the three pieces of information that you need. The angle is between the two sides, so triangles ABD and AEC are congruent by Side-Angle-Side similarity.
