Which expression can be used to find 40% of 130
Answers
if it helps you any just translate 40% to .4 just do 40/100, there are two zeros in 100 so move the decimal of 40. over two places 40%=40/100=.4
130*.4=52 so therefore 52 is 40% of 130
130 x .4 = 52
52 is 40% of 130

Answer:
x = 5
Step-by-step explanation:
given the equation
4x + 10 = 30 ( subtract 10 from both sides )
4x + 10 - 10 = 30 - 10 ( simplify both sides )
4x = 20 ( divide both sides by 4 )
x =

The specified formula y = (x-1)(4x+2)A linear function, -4x² has a constant term of -2 and a linear term of 2x.
To determine whether the function y = (x-1)(4x+2)-4x^2 is linear or quadratic, we can analyze the equation and identify its terms.
Start with the equation:
y = (x-1)(4x+2)-4x²
Expand the equation by multiplying the terms:
y = 4x² + 2x - 4x - 2 - 4x²
Simplifying further,
y = 2x - 2.
Analyzing the equation, we can see that there is no x² term. This indicates that the function is linear.
Let's identify the terms of the equation:
Quadratic term: There is no x² term in the equation.
Linear term: The linear term is 2x.
Constant term: The constant term is -2.
Therefore, the given function y = (x-1)(4x+2)-4x² is a linear function with a linear term of 2x and a constant term of -2.

Multiplying (x-1) by (4x+2) the term in x² is x*4x=4x².
If we substract 4x² the term of y in x² will be 0.
The function is not quadratic.
Since 4x*(-1)+2*x=-2x (product of terms in x) : the function is thus linear.
Constant term is -1*2=-2
B.) (2x + 3)(3x + 2)
C.) (2x + 6)(3x + 1)
D.) (6x + 1)(6x + 1)

The correct answer is option B.) (2x + 3)(3x + 2).
Given that the factored form of 6 + 13x + 6 is equivalent to which of the following.
A.) (x + 4)(x + 9)
B.) (2x + 3)(3x + 2)
C.) (2x + 6)(3x + 1)
D.) (6x + 1)(6x + 1)
To determine the factored form of the quadratic expression 6 + 13x + 6, we can apply the factoring technique. We are looking for two binomials in the form (px + q)(rx + s) that, when multiplied, result in the original expression.
To factor the expression, we need to find two numbers whose product is equal to 6 * 6 = 36 and whose sum is equal to 13.
The numbers that satisfy these conditions are 4 and 9.
Therefore, the factored form of the expression is:
(2x + 3)(3x + 2)
So, the correct answer is option B.) (2x + 3)(3x + 2).
