The formula to find the cost c of a square sheet of a glass is c=25s2 where a represents the length of a side in feet. how much will ricardo pay for a square sheet of glass that is 3 feet on each side

Answers

Answer 1

Answer: To calculate the cost of Ricardo, we just have to substitute the measurement of the length he wants to the function of the cost given. We do as follows:

c = 25s^2
c = 25(3)^2
c = 225

Therefore, the cost would be 225.

Hope this answers the question. Have a nice day.

Solve each question for X , y=-9+x^2

Answers

so basically you want to isolate only one of the variable on one side so
y=-9+x^2
add 9 to both sides
y+9=x^2
square root both sides
$√(y+9)=x$

x= $√(y+9)$

y = -9 + x^2
y + 9 = -9 + 9 + x^2
y + 9 = x^2
√y+9 = √x^2
√y+9 = x
x = √y+9

√ is the square root symbol
