-4 r -10r + -5= -19

-4r + (-10r) + -5=-19

-14r+ -5 = -19

-14r + -5 +5= -19+5

-14r= -14

r=1

The formula, P=V^2/R,gives the relationship between resistance (R), voltage (V) and power (P). Solve the formula for Voltage
riadik2000 [5.3K]
Start by multiplying both sides by R to isolate V².
V² = P·R

Now, take the square root of both sides to get V.

V = √PR

The outside of a picture frame measures 14 in and 20 in 196in^2 of the picture shows find the thickness of the frame
LuckyWell [14K]
The described picture frame can be visualized into two separate parts. The first area is equal to the area using the outermost dimensions for the length and width. 
             Area = Length x Height
              Area = (20 in) x (14 in) 
              Area = 280 in²

We are given that the area is only equal to 192 in². We subtract this value from the computed area.
         Difference = 280 in² - 192 in²
               difference = 88 in²

This area is equal to the area of the hollow space inside the frame. That is equal to,
      height = 20 in - 2x
      length = 14 in - 2x

The area,
               88 = (20 - 2x)(14 - 2x)

Simplify the right hand side of the equation.
             88 = 280 - 68x + 4x²

Divide the equation by 4,
            22 = 70 - 17x + x²

Transposing,
                x² - 17x - 48 = 0
The factors of the equation is 58.2. 

Thus, the thickenss is equal to 58.2 in
