Answer:
Step-by-step explanation:
n+1/2n=7/2
2n^2+1/2=7/2
4n^2+2=14
4n^2=12
n^2=3
n=radical3
Change in y over the change in x
X + (-2) = 4...
do the inverse +2 on both sides 4+2 equals 6. X= 6
5 x 7 = 35 5 rows with 7 items in each row. You can put this down on paper and count each dot or just memorize 5 x 7 =35
