1. A certain ceiling is made up of tiles. Every square meter of ceiling requires 10.75 tiles. Fill in the table with the missing values.
square meters of ceiling
number of tiles
1
10
100

Given :

Every square meter of ceiling requires 10.75 tiles.

To Find :

Number of tiles required at :

Ceiling area                             Number of tiles

       1                                                  

       10

       100

Solution :

For, 1 :

Number of tiles required, n = 10.75 tiles.

For, 10 :

Number of tiles required, n = 10.75 × 10 = 107.5 tiles.

For, 100 :

Number of tiles required, n = 10.75 × 100 = 1075 tiles.

Hence, this is the required solution.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
