he surface area of this triangular pyramid, whose base and lateral faces are congruent equilateral triangles, is square inches.
Dvinal [7]
If we have triangular pyramid with a side of s and all the faces and the base are equilateral triangles, then the formula for the total surface area is
SA = 3As + Ab
Where As is the area of the three faces
and
Ab is the area of the base
Since the triangles are equilateral, the surface area in terms of s is
SA = 3 (√3/ 4) s² + √3/ 4 s²
SA = √3 s²

a.9.9.3=35 is given

or,243=35 (which is false)

b.7+7+7=3+3+3+3+3+3+3

or,21=21 (which is true)

c.2/3/2=2/3

4. Write the linear equation whose graph contains the<br> points (-2,5) and (4,1).
liberstina [14]

Thee linear equation which contains the points (-2,5) and (4,1) is 4x+6y-22=0

Graph The points which is in the equation (-2,5) and (4,1).

Equation is basically a relationship between two or more variables and it is usually in equal to form. It is equated to find the value of variables. We can also make graphs of different equations. Linear equation is a equation whose graph looks like straight line means values comes from a relationship. It not necessarily means parallel to any axis.

The linear equation can be found by:

(y-y_{1} )=(y_{2} -y_{1} )/(x_{2} -x_{1} )* (x-x_{1} ) where the coordinates are (x_{1},y_{1}), (x_{2},y_{2})

(y-5)=(1-5)/(4+2)*(x+2)

(y-5)=-4/6 *(x+2)

6y-30=-4x-8

y=(22-4x)/6

Hence the equation which has points (-2,5)(4,1) is 4x+6y-22=0
