To determine if the lengths given create a right triangle you can set up equations. According to Pythagorean Theorem, the square of the longest side would equal the sum of the squares of the smallest 2 sides.
1st given set: 15 + 25 < 64
This CANNOT be a right triangle. The sum of the 2 smallest sides is less than the sum of the longest side.
2nd given set: 64 + 100 < 256
This CANNOT be a right triangle. Again, the sum of the 2 smallest sides is less than the sum of the longest side.
3rd given set: 3,4,5
This CAN be a right triangle. These 3 numbers are multiples of 7, and if you factored 7 out of them you are left with 3,4,5 which is a triple. Triples are combinations of numbers that are guaranteed to create right triangles. 3,4,5 is one of the most basic triples. Hope this helps!
8(j - 4) = 2(aj - 16)
4(j - 4) = aj - 16
4j - 16 = aj - 16
4j = aj
4j - aj = 0
j(4 - a) = 0
j = 0
The answer is: j = 0.
Answer:
The 13 students on floor
Step-by-step explanation:
The sample is a portion of population selected to view the aspects of population as whole population is difficult to follow. Here, the sample is 13 students on the floor because it is selected from 22 students on the floor.
The population consists of 22 students on floor and 13 out of 20 is the sample because it is a portion of population.
Answer: f(f(f(x)))=8x-7
Step-by-step explanation:
Since we were given f(x) and f(f(x)), We plug that into f(x) again to get f(f(f(x))).
2(4x-3)-1 [distribute]
8x-6-1 [combine like terms]
8x-7
