Answer:
B
Step-by-step explanation:
if we match the two informations we can say that the triangle is isosceles
Answer:
10 to 15
Step-by-step explanation:
the spread is the start and stop of points data. It goes from the least point to the most point, here there is a dot (two technally) on 10 and a dot on 15 where the data stops so the data spread is 10-15
A ) Length = 5 - 2 x
Width = 3 - 2 x
The area of the bottom:
A = L x W = ( 5 - 2 x ) ( 3 - 2 x ) = 15 - 10 x - 6 x + 4 x² =
= 4 x² - 16 x + 15
b ) 4 x² - 16 x + 15 = 10
4 x² - 16 x + 5 = 0
x = (16 - √(256 - 80))/ 8 = ( 16 - 13.266 ) / 2
x = 0.34 in
