Answer:
1.5
Step-by-step explanation:
k= y/x
y= 12-4.5 =7.5
x= 8-3 = 5
k = 7.5/5 = 1.5
Answer:
b=4, h=5
Step-by-step explanation:b(b+1) divided by 2 is 10, so b(b+1)=20 so b^2 + b =20 so b^2 +b -20=0 which equals (b+5)(b-4), giving us solutions -5 and 4. However, -5 is invalid bc it is negative, so base must be 4 making height 5
