Is each of the following a linear function? 4
A. Y = --x
5
A. y = -
Yes
No
B. y = 5x2 - 2
Yes
No
|
C. y = -7
Yes
No

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

step-by-step explanation:

i'm not sure how to show the work for this

answer : c and d or 4(29 + 6)

4(29) + 4(6)

answer is b.
