Find the height of a triangle whose base is 2 inches and area is 8 square inches. 4 in. 4 in. 8 in. 16 in.

[ Answer ]

[ Explanation ]

Area = Base * Height

Base - 2 Inches

Area = 8 Inches

Find Height Based On Base And Area, Considering Area Of Triangle Formula

Half Of 2 Is 1

1 * x = 8

Find x

8 ÷ 1 = 8

Height = 8

Check your work:

Base * Height

1 * 8 = 8

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

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:
