the perimeter of each side is 5 so the answer is 20
4
put it in a calculator and include all the parentheses
Answer:
(1, –5)
Step-by-step explanation:
It is relatively easy to try the offered solutions to see what works.
<u>(1, -5)</u>
3(1) +10(-5) = -47 . . . true
5(1) -7(-5) = 40 . . . true
(1, -5) is the solution
_____
As a check, you can try some of the other choices:
<u>(1, 5)</u>
3(1) +10(5) ≠ -47
<u>(-1, -5)</u>
3(-1) +10(-5) ≠ -47
<u>(-1, 5)</u>
3(-1) +10(5) ≠ -47
None of the other choices works in the first equation, so they're not the solution.
Answer:
X = 2, -8
Step-by-step explanation:
The factors of the equation 
will be 
<h3>What will be the factors of the given equation?</h3>
When we split the equation into two groups we will get
Now taking (x-1) common
Thus the factors of the equation will be
