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)
Answer:
x = 5 ; y = - 3
Step-by-step explanation:
2x - 13 = y
2x - y =13 --------------------(i)
-3x + 2y = -21 ----------------(ii)
(i)*2 ===> 4x - 2y = 26
(ii) ===> <u> -3x + 2y = -21</u>
add ==> x = 5
When we are adding, -2y and 2y gives 0 or cancelled. 4x and -3x gives 1x; 26 and -21 --> different sign so subtract and put the bigger number sign. so it gives 5.
substitute x = 5 in equ (i)
2*5 - y = 13
10 - y = 13
-y = 13 -10
y = 3
y = -3
Answer:
20
