Answer:
From the Pythagorean theorem...
[ distance between (a, 7) and (2, 1) ]2 = [a - 2]2 + [7 - 1]2
And they tell us that the distance equals 3√5 , so
[ 3√5 ]2 = [a - 2]2 + [7 - 1]2
45 = [a - 2]2 + 36
9 = [a - 2]2
±√9 = a - 2
± 3 = a - 2
± 3 + 2 = a
a = 3 + 2 = 5 or a = -3 + 2 = -1
and
5 + -1 = 4

The second image is 3 times the size of the first one so 7 times three gives you 21 =m
Step-by-step explanation:
- – 18q+10q+16q–3= – 19
- 8q=-19
- q=-19/8
- q=-2.375
There is no error, Jacob did everything right :)
-3(6-10v-5v)
=-3(6-15v)
=-18+45v
-18+45v is the final answer.
