Which technique is most appropriate to use to solve each equation?
Drag the name of the technique into the box to match the equation.

↔ zero product property and

↔ square root property.

Solution:

Given expressions are and .

To find which techniques is most appropriate to solve each equation.

Equation 1:

Zero product property states that if AB = 0 then A = 0 or B = 0.

In the equation is , zero product property is used to solve the equation.

(x + 3) = 0 (or) (x + 2) = 0

x = –3 (or) x = –2

Equation 2:

Subtract 6 from both sides of the equation.

Take square root on both sides of the equation.

x = 5

Square root property is used to solve the equation.

Hence ↔ zero product property and

↔ square root property.

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
