4m² when m = 3 in math form

Answers

Answer 1

Answer:

Answer:

HOPE THIS HELPS YA OUT!!

Step-by-step explanation:

To express 4m² when m = 3 in math form, we substitute the value of m into the expression.

Given that m = 3, we can replace m with 3 in the expression 4m²:

4m² = 4(3)²

Simplifying further:

4(3)² = 4(9)

Multiplying:

4(9) = 36

Therefore, when m = 3, the expression 4m² simplifies to 36 in math form.

What is equation?

An equation is arrangement of variables and coefficient which provides to understand given statement in form of numbers .That means a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.

How to solve?

Given equation y=5x+10 and other equation y=5x+2

to check if two have any solution possible we will substitute value and check if RHS=LHS or not

∴y=5x+10=5x+2

=5x+10=5x+2

⇒0= -8

hence RHS≠ LHS hence no solution is possible

The system of equations
$\left \{ {{y = 5x + 10 } \atop { y = 5x + 2}} \right.$

you can easily see that they are contrary to the equation . We not solve them . However prove it.

by substitution .
We substitute the value of y from the first equation to the second equation

y = 5x + 10
y = 5x + 2

y = 5x + 10
5x + 10 = 5x + 2

y = 5x + 10
5x - 5x = 2 - 10

y = 5x + 10
0 ≠ -8

or by opposing coefficients
y = 5x + 10 [* (-1)
y = 5x + 2

-y = -5x - 10
y = 5x + 2
----------------- sum
0 ≠ -8

Non example of infinite solution non example of equations with one solution

non example of equations with no solutions

Answers

it cant be solved but there is an infinite ways this could be taken

Final answer:

An equation such as x + 3 = 5 is a non-example of infinite solutions, having only a single solution. An equation such as 2x+3=2x+5 is a non-example of an equation with one solution because it has no solution. A non example of an equation with no solutions would be 3x - 5 = 6, as it has one solution.

Explanation:

In Mathematics, when we are working with equations, they can have one, infinite or no solutions. A non-example of infinite solutions would be an equation like x + 3 = 5, which has only one solution, x = 2. A non example of an equation with one solution is 2x + 3 = 2x + 5 which has no solution as whatever the value of x, the equations won't match. A non example of equations with no solution is the equation 3x - 5 = 6, this equation has exactly one solution, i.e., x = 11/3.

Alice spins the spinner 3 times. What is the probability that she spins an A, then a B, and then a C?A. 1/3
B. 1/9
C. 1/27
D. 1/12

Answers

I believe it is A.1/3 because there are 3 letters, so that is automatically the denomitor. And there is only 1 letter chosen in this problem so that would be 1/3. To convert that to a percentage or to put it in decimal form, it would be this:
Percentage: 33.3%
Decimal Form: .3

A: 2x - 3y = 6B: 3x - 2y = -9
C:y=-x-5
D:y= {x2
