Rachel has a toy shaped like a triangular pyramid in which the base and the lateral faces are congruent equilateral triangles. The side lengths of
the triangles are 4 inches. The height of each triangle is about 3.5 inches, Rachel wants to cover all the lateral surfaces except for the base with
yellow paper.
The amount of paper required to cover the lateral surfaces is about ___square inches. If she wants to cover the entire pyramid with yellow paper, she would require about ___more square Inches of paper

1. Lateral surface area: 7x4 = 28 inch^2

2. Total surface area: 1/2 x 3.5 x 4 x 5 = 35inch^2

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
