Jack and luke were wrapping presents. jack was able to wrap presents at a constant rate of 3 presents every 15 min. luke was able to wrap presents at a constant rate of 5 presents every 20 min. each boy had 20 presents to wrap, and the boys started wrapping presents at the same time.

write an equation to find the rate each boy wraps presents. you may use y=kx or w=rt (4 points 2 for each)

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
