Answer:
x = 5 + sqrt(7) or x = 5 - sqrt(7)
Step-by-step explanation by completing the square:
Solve for x:
x^2 - 10 x + 26 = 8
Subtract 26 from both sides:
x^2 - 10 x = -18
Add 25 to both sides:
x^2 - 10 x + 25 = 7
Write the left hand side as a square:
(x - 5)^2 = 7
Take the square root of both sides:
x - 5 = sqrt(7) or x - 5 = -sqrt(7)
Add 5 to both sides:
x = 5 + sqrt(7) or x - 5 = -sqrt(7)
Add 5 to both sides:
Answer: x = 5 + sqrt(7) or x = 5 - sqrt(7)
This conclusion is not valid because BOTH SOIL BRANDS WERE NOT SUBJECTED TO THE SAME CONDITIONS.
Carlisle applied brand A to the part of the yard that received full sunlight while brand B was applied to the area of the yard which received partial sunlight. This implies that the soils were subjected to different conditions and this ought not to be so, since sunlight is a very important factor, which the soils need.

Answer:
∠MPQ ≅ ∠MPR: Reason; Corresponding parts of congruent triangles are congruent (CPCTC)
∠PQR ≅∠PRQ: Reason; CPCTC
Step-by-step explanation:
: Reason; Given
Draw 
so that M is the midpoint of 
: Reason; Two points determine a line
: Reason; Definition of midpoint
: Reason; Reflexive property
ΔPQM ≅ ΔPRM: Reason; Side Side Side (SSS) rule for triangle congruency
∠MPQ ≅ ∠MPR: Corresponding parts of congruent triangles are congruent CPCTC
∠PQR ≅∠PRQ: CPCTC
