Mr Thomas wants to protect his garage by installing a flood barrier. He connects 2 barriers side by side. Each barrier is 9 feet

bezimeni [28]

Answer:

36 square feet,

Step-by-step explanation:

Given:

Mr Thomas wants to protect his garage by installing a flood barrier.

He connects 2 barriers side by side

Each barrier is 9 feet long by 2 feet high ( breadth)

Question asked:

What is the combined area of the barriers ?

Solution:

Length of each barrier = 9 feet

As he connects 2 barriers side by side, the length will be doubled but height (breadth) will be unchanged.

Total length of two barriers = 9 + 9 = 18 feet

Height (breadth) of the barriers = 2 feet

By using, Area of rectangle = $length \times breadth$

= $18 feet \times 2feet = 36 square feet$

Therefore, combined area of the barriers is 36 square feet,

Solve the equation using the zero product principle<br> (x-3)(x+6)=0

Wittaler [7]

Zero product states : if a * b = 0, then a = 0 and/or b = 0

(x - 3)(x + 6) = 0

x - 3 = 0
x = 3

x + 6 = 0
x = -6

so x = 3 and x = -6
