Find the surface area of the pyramid. The side lengths of the base are equal.

☁️Answer☁️

☕251.6☕

Hyung~! -3-

195.6 inches squared

Step-by-step explanation:

First we find the value of one of the big triangles.

(14*8*0.5)

56

Next, we find the value of the three of them combined.

56+56+56 or 56*3

168

Now, we find the value of the smaller triangle.

(6.9*8*0.5)

27.6

Because we only have one small triangle, we don't need to do what we did with the other one now.

The last step is to add the area of the three triangles with the smaller triangle.

168+27.6

195.6

The surface area of the (shape...?) is going to be 195.6 in. squared.

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
