Factorize completely 3n2 + 15np

Tomtit [17]

The factor of the given expression 3n² + 15np is 3n(n+5p).

<h3>What is factorization?</h3>

Writing a number or other mathematical object as the result of numerous factors—typically smaller or simpler objects of the same kind—is known as factorization or factoring in mathematics.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Given that the expression is 3n² + 15np. The factor of the expression will be calculated as,

E = 3n² + 15np

Take 3n common from the expression,

E = 3n ( n + 3p)

Therefore, the factor of the given expression 3n² + 15np is 3n(n+5p).

Approximately how many square inches of fabric were used to make the triangular flag? 15 square inches 76 square inches 186 squa

Law Incorporation [45]

The area used to make the triangular flag is 15 square inches.

Given

Two of the sides are 8 in.

Lila made a triangular flag to cheer on her favorite sports team.

The perimeter of the flag is 20 inches.

<h3>What is Heron’s formula?</h3>

Semi-perimeter is equal to the sum of all three sides of the triangle divided by 2.

Then,

The value of S is;

$\rm S = \dfrac{20}{2}\\\\S =10$

Therefore,

The area used to make the triangular flag is;

$\rm Area = \sqrt{s(s-a)(s-b)(s-c)} \\\\A rea= \sqrt { (10)(10-8)(10-8)(10-4) }\\\\Area = \sqrt{10 \times 2 \times 2\times 6}\\\\Area = \sqrt{240}\\\\Area = 15.49$

Hence, the area used to make the triangular flag is 15 square inches.
