Write a pair of equivalent expressions using distributive property
bulgar [2K]
The distributive property "distributes" a number through all numbers/terms in a set of parentheses by multiplication.


EXAMPLES
Equivalent expressions are the first and last steps. The middle step just shows the work.

5(2 + 3x)= (5*2) + (5*3x)= 7 + 15x

4(2x + 4y)= (4*2x) + (4*4y)= 8x + 16y

10(4x + 5)= (10*4x) + (10*5)= 40x + 50


ANSWER:
Only one pair below is needed for your answer.

5(2 + 3x)= 7 + 15x

4(2x + 4y)= 8x + 16y

10(4x + 5)= 40x + 50


Hope this helps! :)

1.what is the sum or difference? 3x^8-7x^8<br>A.-4x^16<br>B. -21x^8<br>C. -4x^8<br>D. 10x^-8
Dafna1 [17]
To simplify the given equation, you want to combine like terms. Since both terms have x^8, we can add the coefficients and leave the x^8
3x^8-7x^8 (do 3-7)
=-4x^8 so the answer is C

Hope this helps

Find x and y. Please help, I will give brainiest answer.
Inessa05 [86]

Answer:

x = 3 and y = 2

x = 1.25 and y = 1.75

Step-by-step explanation:

Part 1:  

See the diagram first.

If the two arrow lines are parallel then, the two triangles are similar.

So, the corresponding sides of the triangles are proportional.

So, \frac{3}{1.5} = \frac{6}{x} = \frac{4}{y}

Hence, x = 3 and y = 2 (Answer)

Part 2:  

See the diagram first.

If the two arrow lines are parallel then, the two triangles are similar.

So, the corresponding sides of the triangles are proportional.

So, \frac{10}{8} = \frac{x + 5}{5} = \frac{y + 7}{7}

⇒ x + 5 = \frac{50}{8} =6.25

⇒ x = 1.25

Again, y + 7 = \frac{70}{8} =8.75

⇒ y = 1.75  

Hence, x = 1.25 and y = 1.75 (Answer)
