What's the Area?

PLS HELP ASAP

The cost to replace the glass is $520.96

Step-by-step explanation:

Area of the rectangle = length × width

Here, length = 5 ft and width = 4 ft

∴ Area = 5 × 4 = 20 ft²

Area of 2 semicircles = 2 × 1/2 × πr² = πr²

Here, radius of both the semicircles = 2 ft

∴ Area = π × 2² = 3.14 × 4 = 12.56 ft²

⇒ Area of the window = 20 + 12.56 = 32.56 ft²

Cost of glass per sq. foot = $16

⇒ Cost of 32.56 sq. ft = 32.56 × 16 = $520.96

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20
