Answer:
1. $1.40
2.$1.75
Step-by-step explanation:
Answer: A
Step-by-step explanation: Take the biggest number and work backwards.
Answer:
50, 48, 14
Step-by-step explanation:
Go through them one by one. The side lengths of a triangle should all plug in to the formula a^2 + b^2 = c^2. The longest side is always c because it is the hypotenuse. The other two sides are interchangeable.
8^2+ 14^2 should equal 17^2.
That simplifies to
64+196=289
That can't be true because the units digits add to 10 instead of 9.
The same method applies to 3, 5, and 6 but from experience I know that this already isn't an option.
For 50, 48, and 14, you can divide everything by 2, resulting in 25, 24, and 7.
576+49 should equal 625.
That is true.
For 53, 48, and 24
576+2304 should equal 2809.
That isn't true, it equals 2880.
Answer:
-y^2 - 10 y - x^72 + -1
Step-by-step explanation:
Simplify the following:
-y^2 - 3 y - 5 - (x^36)^2 - 7 y + 4
Multiply exponents. (x^36)^2 = x^(36×2):
-y^2 - 3 y - 5 - x^(36×2) - 7 y + 4
36×2 = 72:
-y^2 - 3 y - 5 - x^72 - 7 y + 4
Grouping like terms, -y^2 - 3 y - 5 - x^72 - 7 y + 4 = -y^2 + (-3 y - 7 y) - x^72 + (4 - 5):
-y^2 + (-3 y - 7 y) - x^72 + (4 - 5)
-3 y - 7 y = -10 y:
-y^2 + -10 y - x^72 + (4 - 5)
4 - 5 = -1:
Answer: -y^2 - 10 y - x^72 + -1
