8z=4(2z+1) show step by step
Verizon [17]
8z=4(2z+1)
First you would distribute the constant into the numbers in the parentheses. so
8z=8z+4
then you would combine like terms which in this case would result in a zero.
8z-8z=0 So the z would be zero or no solution.

PLEASE HELP!!! 20 POINTS WILL BE GIVEN!
77julia77 [94]
SI = PRT /100

1. SI = 400*5*1/100
        = 2000/100
        = $ 20

2. SI = 1000*8.5*3/100
        = 25.5*1000/100
        = $ 255

3.  SI = 200*9*1/2*100
         = 900/100
         = $9

4.  SI = 20000*12*3/100
         = 200*12*3
         = 7200

5.  SI = 1200*4.5*6/12*100
         = 4.5*6
         = $27
  
Amount to pay = Principal + SI
                        = 1200+27
                        = $1227 ( But this answer isn't there in the options )

Find the lateral area of the regular pyramid<br><br> L.A. =
Arisa [49]

Answer:

FOR REGULAR PYRAMID with those dimension.

L.A = 96

FOR HEXAGONAL PYRAMID with those dimension

L.A = 171.71

Step-by-step explanation:

Please the question asked for L.A of a REGULAR PYRAMID, but the figure is a HEXAGON PYRAMID.

Hence I solved for both:

FOR REGULAR PYRAMID

Lateral Area (L.A) = 1/2* p * l

Where p = Perimeter of base

P = 4s

P = 4 * 6

P = 24cm

l = slanted height

l = 8cm

L.A = 1/2 * 24 * 8

L.A = 1/2 ( 192)

L.A = 96cm ^ 2

FOR AN HEXAGONAL PYRAMID

Lateral Area = 3a √ h^2 + (3a^2) / 4

Where:

a = Base Edge = 6

h = Height = 8

L.A = 3*6 √ 8^2 + ( 3*6^2) / 4

L.A = 18 √ 64 + ( 3 * 36) / 4

L.A = 18 √ 64 + 108/4

L.A = 18 √ 64+27

L.A = 18 √ 91

L.A = 18 * 9.539

L.A = 171.71
