Answer:
2) 92.2km
3) B
4) 4.8m
Step-by-step explanation:
Equation: a² + b² = c²
2)
60² + 70² = c²
3600 + 4900 = c²
8500 = c²
√8500 = c
92.2 = c
3)
12² + 4² = c²
144 + 16 = c²
160 = c²
√160 = c
12.6 = c
4)
4.5² + 1.6² = c²
20.25 + 2.56 = c²
22.81 = c²
√22.81 = c
4.8 = c
The answer is A. x = 8. All the points on the line are ( 8 , y ).

Answer:
The sum of two numbers is 14 and their difference is 10
Step-by-step explanation:
"2 numbers (x and y)
x+y = 14
and x-y + 10
If you each equation by positive 2, one gets 2x+2y = 28 and 2x-2y = 20
The 'y-terms' cancel out or equal zero when adding, so 4x = 48, divide by 4 on each side and x or the first number equals 12.
Plug 12 back into the equation for 'x' and subtract 12 on both sides so that y=2
The difference of 12-2=10 and the addition of 12 and 2 equals 14"
