First line because 4(2a+1)=8a+4 and 9a+4-(8a+4)= a
Second line because a times 2 =2a and 2a+1-2a=1
<span>Although the second equality is more or less obvious since 2a+1 leaves a remainder of 1 when divided by a.</span>
Answer:
Step-by-step explanation:
E and F are horizontally aligned, so the slope of EF is 0 and its length is 16-10 = 6.
G and H are horizontally aligned, so the slope of GH is 0 and its length is 16-10 = 6.
F and G are vertically aligned, so FG is vertical and its length is 10-4 = 6.
E and HG are vertically aligned, so EH is vertical and its length is 10-4 = 6.
Quadrilateral EFGH is a square.
