Answer:
x = 5.5 (nearest tenth)
Step-by-step explanation:
let x be the length of 1 side
given area of square poster is 30 in²
and
Area = (length of 1 side )²
hence
30 = x²
x = √30
x = 5.4772
x = 5.5 (nearest tenth)
Answer:B
Step-by-step explanation:
20 one hundred bills = 2000
2000 divided by 10 = 200
The answer is 200
X=8.5 because angle B and angle D are congruent using alternate interior angles theorem. so you would find the measure of B by adding 50+45 to get 95, then subtract 95 from 180 to get 85 degrees for angle B. Now your equation is 10x=85 so if you divide 85/10 you get x=8.5! hope this helped :)
use the distance formula

You ll need to do it t times:
x1 y1 x2 y2
(-1, 5) (4, 2) = (-1, 5) (4, 2)
(4, 2) (0,0)
(0,0) (5,5)
(5,5) (-1, 5)
then add all your results
