Arectangular picture frame measures 4.0 inches by 5.5 inches. to cover the picture inside the frame with glass costs $0.99 per square inch. what will be the cost of the glass to cover the picture? a. $6.60 b. $198.00 c. $198.66 d. $21.78

$21.78

Step-by-step explanation:

Given : A rectangular picture frame measures 4.0 inches by 5.5 inches.

We know that the area of rectangle =

Then, the area of the rectangular picture =

Also, it is given that , to cover the picture inside the frame with glass costs $0.99 per square inch.

Then, the cost of the glass to cover the picture = $0.99 x Area of picture

⇒ The cost of the glass to cover the picture

∴The cost of the glass to cover the picture = $21.78

Hence, the correct answer is  Option D. $21.78

step-by-step explanation:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
