Factor completely 49m4 + 140m2 + 100
Answer:
Step-by-step explanation:
Use identity : (a + b)² =a² + 2ab + b²
49m⁴ + 140m² + 100 = 7²(m²)² + 2 * 7m² * 10 + 10²
= (7m²)² + 2 *7m²*10 + 10²
= (7m² + 10)²

Answer: x=7.2
Step-by-step explanation:
Use the Pythagorean theorem:a^2+b^2=c^2 c being the hypothenuse and b and a being the other 2 sides
so 7.8*7.8=60.84 3*3+9 60.84-9=51.84 then the square of that would be 7.2 so x=7.2

What is the numerical coefficient in the polynomial 4y+ 6?
Answer:
4y
Step-by-step explanation:
A coefficient is a number with a variable and no sign in between them.
The numerical coefficient in the polynomial 4y+ 6 is 4.
What is expression?A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation. Let's examine the writing of phrases. The other number is x, and a number is 6 greater than half of it. In a mathematical expression, this proposition is denoted by the equation x/2 + 6.
A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.Coefficient: A coefficient is a number that is multiplied by a variable in an expression.Given expression:
4y + 6
As, A coefficient is a number that is multiplied by a variable in an expression.
here the term that contain variable is 4y.
So, the coefficient is 4.
Hence, the numerical coefficient in the polynomial 4y+ 6 is 4.
