Answer:
Once.
Step-by-step explanation:
When the equation is graphed the x-axis is intersected/touched only once.
It crosses the x-axis at coordinates (-1 , 0)
When graphed it looks like this:
Step-by-step explanation:
-3(-x -3y) = 3( x +3y) = 3x+9y
Answer:
Step-by-step explanation:
Answer:
16 ft²
Step-by-step explanation:
The complete question is attached.
A trapezoid is a quadrilateral (has four sides) with one a parallel base. The base angles and the diagonals of an isosceles trapezoid are equal.
The area of a trapezoid = [(sum of the parallel bases) / 2] * height of the trapezoid.
Given that the parallel bases are 3 ft and 5 ft, while the height of the trapezoid is 4 ft. Hence:
The area of a trapezoid = [(3 + 5)/2] * 4
The area of a trapezoid = 16 ft²
Answer:
42.25 inches²
Step-by-step explanation:
Given that the tile has a square shape, and each side of the tile is 6.5 inches, the area covered by one tile in square inches = area of square = s².
Where, s = side length of square
Area of 1 tile = 6.5² = 42.25 square inches.
One tile covers 42.25 square inches.
