The letter b represents a nonzero constant. solve bx=-7 for x

Step-by-step explanation:

We have been given an equation , where b represents a nonzero constant. We are asked to solve for x.

We will use opposite operations to solve our given problem.

Since b represents a nonzero constant, so we can divide both sides of our equation by b as:

Therefore, the solution of our given equation would be .

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
