Answer:
L(x)=136x−487
Step-by-step explanation:
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
X/10 = 10/4x
4x^2 = 100
x^2 = 25
x = 5
answer
5 units
I would say solve for x in the second equation
