Answer:
option B)
Explanation:
Given the Quadratic equation
x² + 6x= 146
A)
The front of a cereal box has an area of 146 square inches. The area that is coloured is 6 times more than the area that is shaded.
x + 6x = 146
B)
A garage door is 6 feet wider than it is tall. The area of one side of the garage door is 146 square feet.
suppose, length of door = x
so, wight = 6 + x
area = l x b
146 = x * (x+6)
146 = x² + 6x
C)
Matt has a dirt patch in his yard that has an area of 146 square feet. He covers 6 square feet of the dirt with sod.
146 - 6 = 140 area of dirt patch left
D)
Lacey is constructing a model of a house from a blueprint. The area of the blueprint is 146 square inches. The area of the floor of the model is one-sixth of the area of the blueprint.
Area of the floor of the model =1/6 of the area of the blueprint
= 1/6 x 146
= 24.33 ft²
