Which system of equations is represented by the graph? (2 points)
y = x2 - 6x - 7
x - y = 1
y = x2 - 6x + 7
x + y = -1
y = x2 + 6x - 7
x - y = 1
y = x2 + 6x + 7
x + y = 1

75 square inches

Step-by-step explanation:

Area of a Triangle = 1/2 × Base × Height

From the above question:

Base = 30 Inches

Height = 5 inches

Hence:

Area = 1/2 × 30 in × 5 in

Area = 75 square inches

Therefore, the area of one of the triangular pieces of wood that she needs to build the ramp is 75 square inches
