2x + 8 = 20
2x = 20 - 8
2x = 12
x = 12/2
x = 6.....he ran 6 miles on Tuesday...also ran 6 miles on Friday

Answer:
a = 84°
Step-by-step explanation:
∠ QPR and ∠ TPR are adjacent and supplementary, thus
∠TPR = 180° - 123° = 57°
Given there are parallel lines , then
∠ PTR = 27° ( alternate angle )
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ TRS is an external angle , thus
∠ TRS = a = 57° + 27° = 84°
Answer:
B. 3x² – 10x + 13
Step-by-step explanation:
given:
f(x) = 3x² – 8x + 5
g(x) = 2x – 8
f(x) - g(x)
= (3x² – 8x + 5) - (2x – 8)
= 3x² – 8x + 5 - 2x + 8
= 3x² – 10x + 13
