Step-by-step explanation:
First allocate the power of three to every number
= 
not sure what you mean by positive exponents, the exponents already are positive. Maybe you mean positive exponents and integers?

First, let's solve the subtraction (in parentheses):


Now, let's solve the multiplication. Remember: in multiplication, two negative numbers will give a positive number:


Finally, let's solve the division:

<h3><u>Answer</u>: 16</h3>
More than 2 ... there is a right and a obtuse i think
Answer:
[6.5,-7.25]
Step-by-step explanation:
Given the partitioning ratio as 3:1
#Find the length of the x-coordinate and multiply by the ratio:
x length=9--1=10
=>
#We subtract 2.5 from the x-max to get the point=9-2.5=6.5
#Find the length of the y-coordinate and multiply by the ratio:
x length=-9--2=-7
=>
#We subtract -1.75 from the y-max to get the point=-9--1.75=-7.25
Hence, the coordinates that partitions the segment into a ratio of 3 to 1 is [6.5,-7.25]
The best step to do next is to add 80 to both sides of equation:
5 ( x² + 8 x ) + 80 = 14 + 80
and since 80 = 5 · 16
5 ( x² + 8 x + 16 ) = 94 Answer : B )
After that we will continue like this:
5 ( x + 4 )² = 94
( x + 4 )² = 18.8 ... etc
