Ima mark as brainlist if u help plsss

Hence the disagree with Ima. He used the wrong formula to find the total surface area

Step-by-step explanation:

Surface area of the triangular prism = 2B + pH

B is the base area= 1/2 * 13 * 5

B = 65/2

B = 32.5 m^2

p is the base perimter = 5 + 12 + 13

p = 30m

H is the height of the prism = 8m

Substitute

TSA = 2(32.5) + 30(8)

TSA = 65 + 240

TSA = 305m^2

HEnce the total surface area is 305m^2

Hence the disagree with Ima. He used the wrong formula to find the total surface area

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.
