Perimeter= add all sides.
Since this is a rectangle, we can assume two sides equal 3 and two equal 4. Therefore, 3+3+4+4= 14
Area=sidexside
Therefore, 3x4=12
Answer:
Jessica: 10 dimes, 6 quarters
Whitney: 20 dimes, 2 quarters
Step-by-step explanation:
7x is the GCF of the polynomial.
<h2>Polynomial</h2>
Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.
Given
21x + 56xy is a polynomial.
<h3>To find </h3>
The GCF to factor the polynomial.
<h3>How to find the GCF to factor the polynomial?</h3>
21x + 56xy is a polynomial.
Take 7x common from the polynomial. we have
21x + 56xy
7x (7 + 8y)
Thus, 7x is the GCF of the polynomial.
