The sides of a rectangle are 2x + 3 and 14. What are 2 expressions that represent the area of the rectangle?

28x+42

14(2x+3)

Step-by-step explanation:

Area of a rectangle is lenght times width

A = L * W

So

14(2x+3)

28x+42

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
