Which equation is not a linear equation? Question options: a) –4v + 2w = 7 b) x4= y c) x = -5 d) 2x + 3y = 5
Semmy [17]

Answer: Option b

x^4= y

Step-by-step explanation:

Linear equations have the following form:

a_1x^n + a_2y^m + a_3w^s + a_4v^h = b

Where the exponents n, m, s and h are always 0 or 1

To know which equations are nonlinear, identify among the options given, those that have exponents other than 1 or 0

Note that in option b) the exponent of the variable x is n = 4 therefore the equation is nonlinear

Finally the answer is the option b

Write an expression that represents the area of the rectangle. Remember A = LW
Iteru [2.4K]

Answer:

b) 9x² - 3x

Step-by-step explanation:

Area of a  rectangle = Length × Width

Area for the rectangle = 3x - 1 × 3x

Area = (3x-1)(3x)

Step 1. Multiply by combining like terms

3x · 3x = 9x²

Step 2. Multiply -1 by 3x

-1 · 3x = -3x

Step 3. Combine 9x² and -3x

9x² - 3x
