Answer:

Step-by-step explanation:

28=-4 (d-79)+100

28=-4d+316+100

4d=316+100-28

4d=388 (divide both side by 4)

d=97

1. Which of the following shows the correct use of the Distributive Property when solving 1/3( 33

vagabundo [1.1K]

Answer:

The option $(\frac{1}{3}\times 33)-\frac{1}{3}y=\frac{1}{3}135.2$ is correct

Step-by-step explanation:

Given equation is $\frac{1}{3}(33-y)=135.2$

The option shows correct usage of distributive property is

$(\frac{1}{3}\times 33)-\frac{1}{3}y=\frac{1}{3}135.2$

( by distributive property $a(x+y)=ax+ay$ here $a=\frac{1}{3}$ , x=33 and y=-y )

Therefore the option $(\frac{1}{3}\times 33)-\frac{1}{3}y=\frac{1}{3}135.2$ is correct.

The length of a rectangle field is represented by the expression 14 X minus 3X squared +2 Y. The width of the field is represent

Assoli18 [71]

Answer:

$9x+4x^2-5y$

Step-by-step explanation:

Hi there!

Length of the field: $14x-3x^2+2y$ units

Width of the field: $5x-7x^2+7y$ units

To find how much greater the length of the field is than the width, subtract the width from the length:

$14x-3x^2+2y-(5x-7x^2+7y)$

Open up the parentheses

$= 14x-3x^2+2y-5x+7x^2-7y$

Combine like terms

$= 14x-5x-3x^2+7x^2+2y-7y\\= 9x+4x^2-5y$

Therefore, the length is $9x+4x^2-5y$ units greater than the width.

I hope this helps!

SVETLANKA909090 [29]

Answer:

35w^3 + 44w

Combine Like Terms:

= 35w + 9w + 35w^3 + 25w^3 - 25w^3

= (35w^3 + 25w^3 - 25w^3) +(35w + 9w)

= 35w^3 + 44w

Hope this is right ♡
