For number one you put the number in , so like it says 5-2x you put the number in x in so 5-2•-1
It would be x to the 1/4. Just like how the square root of x is to the power 1/2. Its just something you have to remember that the root is the denominator and the power under the radical is the numerator
Line segment AB and CD both are congruent with the length of 16 units.
We have been given two line segment AB and CD of whose coordinates are :
A = -7 , B = 9 and C = -4 , D = 12
The distance formula is given as |x2 – x1|
Therefore the length of AB = |9 – (-7)|
= 9 + 7
= 16
The length of CD = |12-(-4)|
= 12 + 4
= 16
Note that when two line segments are congruent then their distance is equal.
Thus both the line segment AB and CD are congruent with a length 16 unit.

Answer:
21
Step-by-step explanation:
y= 2/3 x
so, x= 3/2y
when y= 14
x= 3/2×14 = 21
