Therefore, 2 is the only correct solution out of the given answer choices.
We know that
<span>the triangle DEF is translated following the rule
</span>(x,y)-----> (x+2,y+2)
in the translation the figure maintains its dimensions
so
the area of triangle DEF is equal to the area of the triangle D’E’F’
therefore
the answer is
<span>The area of triangle D’E’F’ is equal to the area of triangle DEF. </span>

Liz's annual pension is $1470
Step-by-step explanation:
Salaries for the last four years are $66,000; $66,000; $73,000; and $75,000
Finding the average salary in the four years will be;
Sum $66,000 + $66,000 + $73,000 + $75,000 =$280,000
Number of years =4

Applying 2.1 % pension
$70,000 * 2.1/100 =$1470 annual pension
