Answer:
8.6
Step-by-step explanation:
This uses the Pythagorean Theorem
a^2 + b^2 = c^2
a = 5
b = 7
c = ?
5^2 + 7^2 = c^2
25 + 49 = c^2
74 = c^2
sqrt(c^2) = sqrt(74)
c = 8.60 which when rounded = 8.6
The answer is 1.70 for the 8 apples
Answer:
The student is incorrect.
Step-by-step explanation:
When you add the absolute value lines around a negative number, it becomes a positive number. If you add them to a positive number, it stays positive. Since the student added them to -9, the number would become 9 which if greater than 4.
All u do is change the f(x) back to a Y and u got it
560 ft^2
20ft x 10ft = 200 ft^2
+
12ft x 30ft = 360 ft^2
=
560 ft^2
