a. The total area of the model is 110 m2. Write an equation to find x. b. Solve the equation by completing the square. (x + 2)(2x + 2) = 110; x = 5.93 m (x + 2)(x + 2) = 110; x = 1.32 m (x + 2)(2x + 2) = 110; x = 3.53 m (x2 + 2)(2x + 2) = 110x; x = 5.93 m

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:
