Answer:
The answer is first point, A = 67.5units²
Step-by-step explanation:
Given that the area of triangle is (1/2)×base×height. So use this formula to find the area :
base = 9units
height = 15units
Area = (1/2)×9×15
= 67.5units²
Answer:
5
Step-by-step explanation:
13 = -2(y - 4) + 3y
13 = -2y + 8 + 3y
13 = y + 8
5 = y
y = 5
Answer: Hey I don't have answer but there a app called Calculator soup and its very helpful also I'm not a bot :]
Step-by-step explanation:
-4/7 (decimal form (.571))
Distance formula : d = sqrt (x2 - x1)^2 + (y2 - y1)^2
(-5,-1)(-1,12)
d = sqrt (-1-(-5)^2 + (12 - (-1)^2
d = sqrt (-1 + 5)^2 + (12 + 1)^2
d = sqrt (4^2) + (13^2)
d = sqrt (16 + 169)
d = sqrt 185
d = 13.60 <==
