A) 38*(1-20%)*(1-10%)=27.36
b)38*(1-30%)=26.6
c)Because in question one when you take off the 10% it is 10% of the already off price but when you take off 30% it is taking off from the original price
Answer:
9) 130° (vertical to 130°)
10) 50° (supplementary to 130°, 180° - 130° = 50°)
11) 130° (alternate exterior to 130°)
12) 130° (vertical to 130°)
Step-by-step explanation:
To solve this polynomial equation, we first factor the left side.
To factor x² + 8x + 12 = 0, look for factors of 12 that add to 8.
These factors are 6 and 2 so we have (x + 6)(x + 2) = 0.
So either x + 6 = 0 or x + 2 = 0 and solving for
x in each equation, our answer is {-6, -2}.

The answer of your question is:
Step-by-step explanation:
Solve p² + 4p = 1
p² + 4p + (2)² = 1 + (2)²
(p + 2)² = 1 + 4
(p + 2)² = 5
(p + 2) = ±√5
p1 + 2 = √5 p2 + 2 = -√5
p1 = √5 - 2 p2 = -√5 + 2
p1 = 0.23 p2 = -0.23
