Completely factor the polynomial. 16x 2 - 25

Sunny_sXe [5.5K]

Answer:

(4x-5)(4x+5)

Step-by-step explanation:

16x^2 - 25

Rewriting

(4x)^2 - 5^2

We recognize that this is the difference of squares

a^2 - b^2 = (a-b) (a+b)

(4x)^2 - 5^2 = (4x-5)(4x+5)

Determine whether the triangles are similar. or not.

mr Goodwill [35]

Answer:

Step-by-step explanation:

We know that ∠ $ABE$ ≅ ∠ $DBC$ because they are vertical angles, so that's one pair of congruent angles. However, we can't compare ∠ $BAE$ and ∠ $DCB$ as they have different measures, so we'll have to find the measure of either ∠ $AEB$ or ∠ $BDC$ . Let's go with the former. Using the fact that the sum of the measures of the interior angles of a triangle is $180$ °, we know that $m$ ∠ $AEB=180-(53+42)=180-95=85$ °. Now, we know that ∠ $AEB$ ≅ ∠ $DCB$ because their measures are equal. That's another pair of congruent angles. Therefore, the angles are similar by $AA$ . Hope this helps!
