Answer:
HL
Step-by-step explanation:
PQ = PR {hypotenuse}
PS = PS {Reflexive property, PS is the leg of the both triangles}

Answer:
<h2>- 234</h2><h2 />
Step-by-step explanation:
a83 = 12 + (83 - 1)(-3) = 12 + (82)(-3) = -234
-2(2x - 0.8) = 21.6
-4x + 1.6 = 21.6
-4x = 20
x = -5
Step-by-step explanation:
use the identity a²-b²=(a-b)(a+b)
x²-4=(x-2)(x+2)
so the answer is x-2
