The sum of two numbers is 44.The larger number is 20 more than the smaller number. What are the numbers?

Answers

The smaller number is 'x' .
The larger number is (x+ 20)

Their sum is [ x + (x + 20 ]

2x + 20 = 44

Subtract 20 from each side:

2x = 24

Divide each side by 2 :

x = 12
and
x + 20 = 32
Let the numebrs be x and y.

x + y = 44
x = y + 20

Substituting the value of x,

(y + 20) + y = 44

2y + 20 = 44
2y = 24
y = 12.

x = y + 20
x = 12+ 20

Thus, x = 32.

Thus, the two numbers are 32 and 12.

How can you use the Zero Product Property to solve quadratic
equations in factored form?

Answers

Answer:

The Zero Product Property states that if ab = 0, then either a = 0 or b = 0, or both a and b are 0. When the product of factors equals zero, one or more of the factors must also equal zero. Once the polynomial is factored, set each factor equal to zero and solve them separately.

Step-by-step explanation:

I hope that helps!
