It is called a scalene triangle
Well,properties can help you because you can shorten or make an equation more understandable, like using distributive property in the example 2(5x-3), you can rewrite it as 10x-6. See?
Answer:
C
Step-by-step explanation:
SA=4*pi*r^2
SA=4*pi*2^2
SA=4*pi*4
SA=16*pi m^2
SA≈50.2654824574
SA≈50.3 m^2
Which is C
(-x)+2•4/2=6
-x+8/2=6
-x+8=12
-x=4
x=-4
Answer:
Train A = 214
Train B = 86
Step-by-step explanation:
a + b = 300
a - b = 128
a + b = 300
a = 128 + b
(128 + b) + b = 300
128 + b + b = 300
128 + 2b = 300
2b = 300 - 128
2b = 172
b = 172 ÷ 2
b = 86
a = 128 + b
a = 128 + (86)
a = 214
