If the surface area for the coloured tile is 286cm², find the
value of x.

pls hlp（-""-；)

x=8.72389

Step-by-step explanation:

first you make every number 10 times larger

25*10, 48*10, etc etc

you find that you have 12x

the difference between the two surfaces is

120000 (250*480)- 28600= 91400

12x²+20=91400

12x²=91400-20

12x²= 91380

x²=91380/ 12

x²= 7615

x= √7615

x= 87.2389

and since we had made everything 10 times bigger

x=8.72389

i hope you understand i am not good with the words but i think you can understand what i did.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
