The answer is 0.03. Hope I help:)
Answer:
Mia is incorrect.
Step-by-step explanation:
She confused the area and perimeter.
Area is length x width, in this case 12 x 5 = 60
Perimeter is length² × width², and in this case, it is 12² × 5² = 34
Area = 60 inches
Perimeter = 34 inches
Hope that helps and have a great day!
Answer: x = -5, 3/2 y = 10, 7/2
Explanation:
y = 2x^2 + 6x - 10 (1)
y = - x + 5 (2)
=> 2x^2 + 6x - 10 = - x + 5
2x^2 - 7x - 15 = 0
(2x - 3)(x + 5) = 0
=> 2x - 3 = 0
2x = 3
x = 3/2
=> x + 5 = 0
x = -5
According to (2):
y = -x + 5
y = -(-5) + 5
y = 5 + 5 = 10
y = -x + 5
y = -(3/2) + 5
y = -(3/2) + 10/2
y = 7/2
When you multiply or divide two positives or two negatives, the answer is positive.
72/9 = 8
-72/(-9) = 8
Correct answer: Choice D.
