Answer:
Total surface area of the prism = 920 cm²
Step-by-step explanation:
Given prism has 2 similar triangular surfaces and 3 rectangular surfaces of different dimensions.
Area of one triangular side =
Area of 2 similar sides = Base × Height
= 8 × 15
= 120 cm²
Area of rectangular side with dimensions 17cm × 20cm
Area of the side = 17 × 20 = 340 cm²
Area of the second rectangular side with dimensions 8cm × 20cm
Area of the side = 8 × 20 = 160 cm²
Area of third rectangular side with dimensions 20cm × 15cm
Area of the side = 20 × 15 = 300 cm²
Total surface area of the given triangular prism = 120 + 340 + 160 + 300
= 920 cm²
Answer:
x ∈ {-3, 1.2, 1.25}
Step-by-step explanation:
"Solve" is non-specific as to the solution required. We assume you want the x-intercepts.
A graph shows the zeros to be ...
- x = -3
- x = 1.2
- x = 1.25
The equation can be factored as ...
y = (1/2)(x +3)(4x -5)(5x -6)
