Answer: 3 1/3 ft^2
Step-by-step explanation:
Start by converting the inches into feet
1 ft = 12 in
4 in/1 x 1 ft/ 12 in = 4/12 ft = 1/3 ft
Now, imagine just multiply like normal for a rectangle:
Area of a rectangle = base x height
Area of rectangle = (10 ft) (1/3 ft)
Area of rectangle = 3 1/3 ft^2
Lets solve your equation step by step:
(4k + 5)(k + 1) = 0
Step 1: Simplify both sides of the equation:
4k^2 + 9k + 5 = 0
Step 2: Factor left side of equation:
(4k + 5)(k + 1) = 0
Step 3: Set factors equal to 0:
4k + 5 = 0 or k + 1 = 0
k = - 5/4 or k = - 1
Answer: k = - 5/4 or k = - 1
Hope that helps!!!! ( Answer: k = -5/4 or k = -1)
