Answer:
Step-by-step explanation:
Co-ordinates of F, G and H are:
F (-4, 5)
G (1, 10)
H (-9, 10)
You can find the lengths of sides by using the distance formula:
<em>length</em>(FG) = 
= 
units
Similarly,
<em>length</em>(GH) = 10 units
<em>length</em>(HF) = 
units
Hence, perimeter will be:
P = <em>length</em>(FG) + <em>length</em>(GH) + <em>length</em>(HF) = 
units
Answer:
A (3,-2)
B (-2,-1)
C (0,3)
D (3,2)

<u>Answer</u>
18) $51
19) $24
20) <em> Carla's account. </em>
<u>Explanation</u>
18)
Positive sign values means deposit while the negative values means money been withdrawn from the account.
$100 - $18 + $22 - $53 = $51
19)
Positive sign values means money deposited while the negative values means money been withdrawn from the account.
$45 - $17 - $22 + $18 = $24
20)
To get the person with the most deduction, you should add the negative values in the table then compare.
Carla ⇒ -18 + -53 = $-71
Leta ⇒ -17+ -22 = $-39
From here we can see that the account with greatest decrease is<em> Carla's account. </em>
