ANY EXAPLE OF DISTRIBUTIVE PROPERTY FAST!!!

Mathematics
1 answer:
vivado [14]3 years ago
6 0

Answer:

My example: 7(2 + 7) = 7(2) + 7(7)

Formula: x(y + x) = x*y + x*x

Step-by-step explanation:

The distributive property can be represented by the following equation:

x(y + x) = x*y + x*x

Since you are looking for any example, let's plug in a few numbers to the above equation.

Ex) x = 7, y = 2

The example equation with these values is 7(2 + 7)

<u>Solving With Distributive Property:</u>

x(y + x)

<em />

<em>Substitute</em>

<em />

7(2 + 7)

<em>Simplify using distributive property</em>

7(2) + 7(7)

14 + 49 = 63

<em />

<u>Solving using PEMDAS and solving inside the parenthesis first</u>

<u></u>

7(2 + 7)

7(9)

63

The above is an example of solving/siplifying equations with and without the Distributive Property.

Since these numbers are the same, we can conclude that the formula for the distributive property above is correct.

Again, you are looking for an example, so simply pick a value for x and y and substute into this equation: x(y + x) = x*y + x*x

I used 7 and 2 above, but any numbers will work as you are distributing the value outside the parenthesis.

Hope this helps! Let me know if you have any questions.

PEMDAS simpliy means that the solving of equations can be solved by going in the following order:

- Parenthesis (P)

- Exponents (E)

- Multiplication and Division left to right of the expression/equation (M/D)

- Addition and Subtraction (A/S)

This is just a helpful little refrence when applying the order of operations.

*GEOMETRY*please help me find the surface area of the solid along with the volume of it step by step!
Serjik [45]

Surface area of the solid = 7.1781 in²

Volume of the solid = 0.804 in³

Explanation:

Surface area of the solid = surface area of the square prism - 2(base of the cylinder) + lateral surface of cylinder

surface area of a square prism = 2(lw + lh + wh)

l = length = 1 in

w = length = 1 in

h = height = 1 in

\begin{gathered} \text{Surface area = 2(1}\times1\text{ + 1}\times1\text{ + 1}\times1) \\ \text{Surface area = 2(1 + 1 + 1) = 2(3)} \\ \text{Surface area = 6 in }^2 \end{gathered}

using the value π as it is on the calculator

Base area of a cylinder = πr²

2(Base area of cylinder) = 2πr² = 2π(0.25)² = 0.3927

Lateral surface area = 2πrh = 2π(0.25)(1) = 1.5708

Surface area of the solid = 6 - 0.3927 + 1.5708

Surface area of the solid = 7.178 in²

Volume of the solid = Volume of the square prism - volume of the cylinder

Volume of square prism = length × width × height

length = 1 in, width = 1 in, height = 1 in

Volume of the solid = 1 in × 1 in × 1 in = 1 in³

Volume of a cylinder = πr²h

Volume of the cylinder = π × 0.25 × 0.25 × 1 = 0.196

Volume of the solid = 1 - 0.196

Volume of the solid = 0.804 in³

HELP PLEASE I HAVE BEEN STUCK FOR HOURS THIS IS DUE- I'll mark brainliest. In parallelogram WXYZ, diagonal WY is drawn, M and N
dybincka [34]

Answer:

Opposite sides of the parallelogram are equal. Here, 60°+60°+ Angle ZWX + Angle ZYX = 360°

or,2* Angle ZYX = 240° [ Angle ZWX = Angle ZYX]

So, Angle ZYX = 120°

Then, In ∆ENY;

102° + (120-84)° + Angle ENY = 180° [Sum of all angles of a triangle.]

or, 36° + Angle ENY = 78°

So, Angle ENY = 42°
