-3(b - 7)
Multiply -3 into the parenthesis.
= -3b + 21.
Answer: Option b

Step-by-step explanation:
Linear equations have the following form:

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
therefore the equation is nonlinear
Finally the answer is the option b
Answer:
396
Step-by-step explanation:
circumference of a circle is 2 x pi x r = 2 x 63 x (22/7) = 396
Answer:
w > -14
Step-by-step explanation:
Divide both sides by -6.
-6w/-6 = w
84/-6 = 14
Since it's an equality, if the coefficient of the variable is negative, when you divide the sign flips to the opposite.
Quotient of means divide (place division symbol where "and" is located)
-6 ÷ y or
