The product of a number and 4 plus 2 is 14

Mathematically written:

x * 4 + 2 = 14

4x + 2 = 14

4x = 14 - 2

4x = 12

x = 12 / 4

x = 3

Proof:

3 * 4 + 2 = 14

12 + 2 = 14

14 = 14 → both sides of the equation are equal, our answer is correct

Notes:

A number - An unknown number, called a variable, and which is this case is substituted by the letter x

Product - Answer given by a multiplication, therefore, we multiply 4 by x

answer: 25 is the correct answer

step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
