Answer: B. 2=3x+10x^2
Step-by-step explanation:
The expression means the quadratic function equation.
B = 10x^2 + 3x -2 = 0
the equation is [-b ±√(b^2 -4ac)]/2a
b should be +3 to become -3 when it is plugged into the equation, and 'a' should be 10, and c should be -2.
Answer:
1240.4 mm²
Step-by-step explanation:
The surface area of a pyramid = Area of the all sides + Area of base
Each side is a triangle.
With a regular pentagonal pyramid, the area of each triangle is

For the 5 triangles,

Substituting given values,

Area of base = 440.4 mm²
Surface area of a pyramid = 800 + 440.4 mm² = 1240.4 mm²
A) Volume = l * w* h --> V = 7 * 5 * 4 --> V = 140 units³
B) 140 units³: Prism B has the same length, width, and height as A, just rotated.
C) As long as the tree numbers' product is 140 units³, it works.
Prism C: 140 * 1 * 1
Prism D: 14 * 2 * 5
