Are you supposed to multiply these? If so your answer would be (5x*x^2) + (5x*-x) + (5x*-7). This comes out to 5x^3 - 5x^2 - 35x. Hope this helps!

(5x)(x^2 - x - 7)
5x^3 - 5x^2 -35x

Just use the distributive property to distribute the 5x. When you multiply variables with exponents, you add so 5x * x^2 = 5x^(2+1 ). Remember that variables written without exponents like x, are raised to the first power.

Natalka [10]
Hey there! :) How are you? Basically what you said is right. 

Question 1: There are 16 oz (ounces) in a pound, so we do 64/16= 4 lbs (pounds). 

Question 2: If Jack has 3 pounds of pasta, that would mean he has 48 ounces, since 1 pound is 16 oz, so 16*3= 48 ounces. 

Hoped I helped! Have a nice day, and keep smiling! :)

What is 4-2x+8+5x simplified
sveta [45]

Answer: it is 3 • (x + 4)

Step-by-step explanation: We move all terms to the left:

4-2x+8-(+5x)=0

We add all the numbers together, and all the variables

-2x-(+5x)+12=0

We get rid of parentheses

-2x-5x+12=0

We add all the numbers together, and all the variables

-7x+12=0

We move all terms containing x to the left, all other terms to the right

-7x=-12

x=-12/-7

x=1+5/7We move all terms to the left:

4-2x+8-(+5x)=0

We add all the numbers together, and all the variables

-2x-(+5x)+12=0

We get rid of parentheses

-2x-5x+12=0

We add all the numbers together, and all the variables

-7x+12=0

We move all terms containing x to the left, all other terms to the right

-7x=-12

x=-12/-7

x=1+5/7

Please help me with this question :)​
klio [65]

Answer:

y>5/6

Step-by-step explanation:

5y+3>-7y+13

5y+7y>13-3

12y/12>10/12

y>5/6

This is an inequality, which shows where the variable y does or does not exist

from this we can say

y: (-infinity,5/6) (5/6, infinity]

or, y does not exist from (-infinity,5/6)

and does exist from (5/6, infinity]
