Use FOIL
(1-p)(1+p+p^2+p^3+p^4+p^5+p^6)
1+p+p^2+p^3+p^4+p^5+p^6 -1p - p^2 - p^3 - p^4 - p^5 - p^6
1 + p -1p <------------------Answer

Hello!

Answer:

$\boxed{14j+10}$

Step-by-step explanation:

Distributive property: →→ a(b+c)=ab+ac

Order of operations stands for:

↓

Parenthesis

Exponent

Multiply

Divide

Add

Subtract

*Left to right*

Please Excuse My Dear Aunt Sally!

First, you remove parenthesis.

6j+8j+5+5

Then, you add by the numbers from left to right.

6+8=14

14j+5+5

5+5=10

14j+10 is the final answer.

Hope this helps!

Have a nice day! :)

What do i do for this problem

Margaret [11]

The answer would be 20.

The question is asking you to find the value of the expression for when c = 100, so we have to put 100 where c is in the equation. Given that fact, we start with c/5, then put the 100 in for c.
c/5 = ??
100/5 = 20.

X + y = 3, 4y = -4x - 4 System of Equations

alexdok [17]

Answer:

no solutions

Step-by-step explanation:

Hi there!

We're given this system of equations:

x+y=3

4y=-4x-4

and we need to solve it (find the point where the lines intersect, as these are linear equations)

let's solve this system by substitution, where we will set one variable equal to an expression containing the other variable, substitute that expression to solve for the variable the expression contains, and then use the value of the solved variable to find the value of the first variable

we'll use the second equation (4y=-4x-4), as there is already only one variable on one side of the equation. Every number is multiplied by 4, so we'll divide both sides by 4

y=-x-1

now we have y set as an expression containing x

substitute -x-1 as y in x+y=3 to solve for x

x+-x-1=3

combine like terms

-1=3

This statement is untrue, meaning that the lines x+y=3 and 4y=-4x-4 won't intersect.

Therefore the answer is no solutions

Hope this helps! :)

The graph below shows the two equations graphed; they are parallel, which means they will never intersect. If they don't intersect, there's no common solution
