Can you please help me on 6(1+n)=8n-3(n-7)

Mathematics
1 answer:

Answer:

n = 15

Step-by-step explanation:

6(1+n)=8n-3(n-7)

Distribute

6 +6n = 8n -3n +21

Combine like terms

6+6n = 5n +21

Subtract 5n from each side

6+6n-5n = 5n-5n +21

6 +n = 21

Subtract 6 from each side

6-6+n = 21-6

n = 15

I need to find the surface area of the square pyramid! <br> (I know I'm stupid lol)
pogonyaev

Answer:

L = 260 cm^2

Step-by-step explanation:

height h = 12 cm

slant height s = 13 cm

side length a = 10 cm

lateral edge length e = 13.928388277184 cm

1/2 side length r = 5 cm

volume V = 400 cm^3

lateral surface area L = 260 cm^2

base surface area B = 100 cm^2

total surface area A = 360 cm^2

Genda: h = height

s = slant height

a = side length

e = lateral edge length

r = a/2

V = volume

L = lateral surface area

B = base surface area

A = total surface area
