The first is a right triangle because there is a right angle, and it is scalene because none of the sides are congruent.
The second is an obtuse triangle because there is an obtuse angle, and it is an isosceles triangle because two of the sides are congruent.
The third is an acute triangle because all of the angles are acute, and it is an <span>isosceles triangle because two of the sides are congruent.
The fourth is a right triangle because it has a right angle, and it is a s</span><span>calene because none of the sides are congruent.</span>
Answer:
36
Step-by-step explanation:
2(4.5*3)=13.5
2(3+7.5)=22.5
13.5+22.5=36
Cross multiply the fractions as in 20 times D and 13 times 60 and the problem will be 20d = 780. Here you can divide 780 by 20 and the answer is what D equals to.

Answer:
see below
Step-by-step explanation:
Function 1
Find the slope
m = ( y2-y1)/ (x2-x1)
= (-5 -3) /(3 - -1)
= ( -5-3)/(3+1)
= -8/4
= -2
Function 2
Using the points (0,4) and (-1,0)
m = ( y2-y1)/ (x2-x1)
m = ( 0-4)/(-1-0)
= -4/-1
= 4
The function with the greater rate of change is function 2
The answer to the question is 7/8
