The expression which equals 24 is (4 + 2) (3) . Option B

Given the following expression

Let's evaluate each of them. we have

(2 + 4)(3) = 6× 3 = 18

(4 x 2)(3) = 8 × 3 = 24

(4 - 2) + 3 (4 + 3) - 2 = 2 + 3(7) -2 = 2 + 21 - 2 = 23 -2 = 21

Answer:

The mathematical formulations of quantum mechanics are those mathematical formalisms that permit a rigorous description of quantum mechanics. This mathematical formalism uses mainly a part of functional analysis, especially Hilbert spaces, which are a kind of linear space.

The thing that's wrong with the equation is that 2 shouldn't be multiplied by 4 but should have been added.

From the information given, it can be seen that the equation is:

(3x²)(-2x⁴) = 3(-2)x² × x⁴ = 6x^8

Based on the information above, this calculation is incorrect. The correct calculation will be:

(3x²)(-2x⁴) = 3(-2)x² × x⁴

= -6x^6

Therefore, the multiplication should be an addition of the power.

Answer:

Hello! The answer to your question is [tex]\sqrt{29}[/tex], or approximately 5.39.

Step-by-step explanation:

(Two methods)

Method 1:

To solve this problem, we will use the Pythagorean theorem. To create the triangle, you can connect all the points with lines. This will leave you with the base of the triangle as 2 and the leg as 5. We do not know the hypotenuse. Now, we can use the Pythagorean theorem formula:

[tex]a^2 + b^2 = c^2[/tex]

[tex]\sqrt{2^2 + 5^2 } \\= \sqrt{4 + 25} \\= \sqrt{29}\\or 5.39[/tex]

Now, we can substitute our values:

Method 2:

To solve this problem, we will use the distance formula:

[tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]

Our points are:

A(-3, 1) and B(-1, -4)

Now, we substitute our values into the distance formula provided:

[tex]\sqrt{(-1 - (-3))^2 + (-4 - 1)^2} \\= \sqrt{(-1 + 3))^2 + (-5)^2} \\= \sqrt{(2)^2 + (-5)^2} \\= \sqrt{4 + 25} \\= \sqrt{29} \\or 5.39[/tex]

The product (a^2x^3 -5x+3a).(-2a^3x) is -2a^5x^4 + 10a^3x^2 - 6a^4x

-2a^3x * a^2x^3 -2a^3x * - 5x -2a^3x * 3a

Evaluate the products

-2a^5x^4 + 10a^3x^2 - 6a^4x

Answer:

Step-by-step explanation:

A deck of 52 playing cards contains 13 hearts.

If Sara has 12 cards from this deck in her hand and 3 of them are hearts, then:

Total cards remaining in the deck

= total deck - cards Sara has

= 52 - 12

= 40

Total hearts left in the remaining deck

= total heart cards - heart cards Sara has

= 13 - 3

= 10

So there are 40 cards in the deck and 10 of them are hearts.

Answer:

g(x)=-32x

Step-by-step explanation:

When something is reflected over the x-axis. The x doesn't change, it's the y that changes. So let's just generally say you have the point (x, y). Reflecting this over the x-axis means the y is changing, so it becomes (x, -y). And since the g(x) represents the y, you multiply the entire thing by -1. So the new equation becomes: g(x) = -(8(4x)) = -8(4x) = -32x. So the equation is g(x) = -32x or -8(4x) if you want to leave it like how it was before.

Point A on the red line y = x has two locations it could end up. If we follow method 1, then point A shifts upward to point B. Do this to every point on the red line and the entire red line shifts up 4 units.

Or if you decide to shift 4 units to the left (method 2), then point A moves to point C's location. Doing this to every point on the red line shifts the entire line 4 units to the left.
