The area of a triangle is 10 square meters. The height is one meter longer than the base. What are the lengths of the base and height of the triangle?

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

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

i can't solve unless i know what the line is
