Step Justification
1. 4(n−2)=12 Given
2. 4n−8=12 Distributive Property
3. 4n=20 Subtraction Property of Equality
4. n=5 Division Property of Equality

4.Which point is on the line, y=3x+6?

(9, 27)

(−7, 27)

(12, 2)

(4, 18)

Answer 1

Answer:

3- let the width of the rug be x then length = x+6 we get that states-

(x+x+6)2 = 56ft then x+x+6 equals 56/2= 28 equals 2x= 22, x equals 11 dimesions= 11 and 11+6= 11 and 17

Answer 2

Step-by-step explanation:

Ohm's Law is a formula used to calculate the relationship betwzeen voltage, current and resistance in an electrical circuit. To students of electronics, Ohm's Law (E = IR) is as fundamentally important as Einstein's Relativity equation (E = mc²) is to physicists. E = I x R.
