Answer:
B. Pythagorean triple
Step-by-step explanation:
To prove Pythagorean triple, we must prove that
ML² + LN² = MN²
or MN = √( ML² + LN²)
= √( 9² + 12²)
= √( 81 + 144)
= √( 225)
= 15 = value of MN given in diagram (proven)
You can answer this question by writing the story as a math problem. The sentence tells us step by step what the math problem should be.
We start with $29.60 for parts + (and) 1 1/4 hours (or 1.25) x $56 + (and) $40.
So, 29.60 + 1.25 x 56 + 40= c
c = $139.60
#9) 180 - 116 = 64
(3x -13) + ( 2x +4 ) + 64 = 180
5x - 9 + 64 = 180
5x = 180 + 9 - 64
5x = 125
x = 25
#10) 3x - 13
= (3× 25) - 13 = 62
m< A = 62°
The answer is c . hope this helped
