help idk how to do math
use the distributive property
Answer:
Distributive property is when you multiply or add the numbers in the parentheses equally to the number outside the parentheses.
That probably isn't a good answer, here's what I found on google:
To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
Step-by-step explanation:
I'll do #10 as an example:
(x-5)y
distribute the numbers- y(x)-y(5)
without the parentheses- yx-y5
you can't really get an answer by multiplying a number and a variable, or a variable and a variable, so you just leave them and take the parentheses.
Here's #11:
-4(2a-3b+c)
distribute the numbers- (-4*2a)-(-4*3b)+(-4c)
solve- -4*2= -8
-4*3= -12
-8a-(-12)b+4c
*I dunno how to use parentheses for negative numbers but what I did for distributing is pretty much the same thing
Hope this helps you.

Solve the inequality and graph the solution.
3(x+5) > 12
Answer:
x > -1
Step-by-step explanation:
3(x + 5) > 12
Distribute
3x + 15 > 12
Subtract 15 to both sides
3x > -3
Sivide both sides by 3
3x/3 > -3/3
x > -1
Hope this helps and pls do mark me brainliest if you can:)

what two numbers multiply to -36 and add up to 5
Answer:
9 and -4
Step-by-step explanation:
Finding these 2 numbers can be found by guessing and checking. By doing this, it will get you the numbers 9 and -4.
First, test if they multiply to -36:
9(-4)
= -36
Then, check if they add up to 5:
9 + (-4)
= 5
So, 9 and -4 are the 2 numbers that multiply to -36 and add to 5

For the function F(x) = 1/x+1 which of these could be a value of F(x) when x is close to -1?
Answer:
Option B, -10000
Step-by-step explanation:
Step 1: Find the number that would be valid
As the x value gets closer to -1, the y values go to positive and negative infinity. Therefore, the best value out of the options given would be -10,000 since it is the closest to negative infinity.
Answer: Option B, -10000

-8 + 5 ( 1 + x) = 2x - 20
multi step equation, please solve ill give brainliest (with steps)
Answer:
The answer is x=-17/3
Step-by-step explanation:
The Steps:
-8 + 5(1 + x) = 2x - 20
-8 + 5 + 5x = 2x - 20
-3 + 5x = 2x - 20
-3 + 3x = -20
3x = -17
x = -17/3

The equation P = 2m + 15 represents the price P (in dollars) of a bracelet, where m is the cost of the materials (in dollars). The price of a bracelet is $115. What is the cost of the materials? Explain your reasoning.
Answer:
50
Step-by-step explanation:
115 = p
115 = 2m + 15
-15 -15
100 = 2m
/2 /2
50 = m
If you take away like I did in this method it will get you answer (backwards PEMDAS)

= 48
a. The dimensions of the carpet are probably 8 by 8.
b. The area of the floor not covered by carpet is 64, hence 8 x 8.
