Answer: formula
AB= (-1- -3)+((3-1)
(-1+3 )^2+(3-1)^2
2^2+2^2
Sq rt of 8 is 2.83
length of AB is 2
BC= (-3- -1)^2 + (5-3)^2
-3+1 =-2^2+2^2=4+4=8
Sq rt of 8 is 2.828= 2.83
Step-by-step explanation:
Answer:
1/4
Step-by-step explanation:
-1/2 (-5/6+1/3)
Parentheses first
Get a common denominator of 6
-1/2 (-5/6+1/3*2/2)
-1/2 (-5/6+2/6)
-1/2(-3/6)
Simplify the fraction inside the parentheses
-1/2(-1/2)
Multiply
1/4
Answer: -5x³ + x² + 4x + 8
Step-by-step explanation
This is a polynomial expressions of third order.
The equation
(-4x³ + x² ) + (- x³ + 4x + 8)
Adding them together according to their order, we now have
( -4x³ + (-x³) + x² + 4x + 8 )
-4x³ - x³ + x² + 4x + 8
-5x³ + x² + 4x + 8
1. find the greatest common factors of the numerator & denominator
2. regroup the factors to make fractions equivalent to 1
3. multiply the remaining factors
