Answer:
first you take the square root or 0.9, 2.7, 1.7, and 0.4 which will equal=
0.9= ~0.94
2.7=~1.64
1.7=~1.30
0.4=~0.63
0.94 - 1.64 + 1.30 + 0.63 = 1.23
hope this helps! C:
Answer:
=53
Step-by-step explanation:
a=5-b &. a=9+b
combine
5-b=9+b
-4=2b
b= -2
thus, a=7
(-2)^2 + (7)^2
4+49
=53

Answer:
BC = 33.9
Step-by-step explanation:
here,
AB = 17, BC = ?, AC = 38
By Pythagoras Theorem
AB² + BC² = AC²
BC² = AC² - AB²
BC² = 38² - 17²
BC² = 1444 - 289
BC² = 1155
BC = √1155
BC = 33.9
