Answer:

Explanation:

Since it is an equilateral Triangle their sides are the same.

Thus, 4(x - 1) = x + 8 = 2x + 4

But we can take 2 sides to work with:
To solve for x:

4(x - 1) = x + 8
4x - 4 = x + 8
4x - x = 8 + 4
3x = 12
x = 12/3
x = 4

Therefore, x = 4 and the equation involving x is 4(x - 1) = x + 8

Answer:

4

Step-by-step explanation:

An equilateral triangle has 3 equal sides.

So

4(x-1) = x +8

4x-4=x+8

3x=12

x=4

Same result obtained when comparing the other pairs of equations.

M+5n=p for m <br> Solving for a variable
Verdich [7]

Answer:

M=p-5n

Step-by-step explanation:

Here we are given that M+5n=p

We are asked to solve this equation for M. In order to do that we will follow these steps.

Subtracting 5n from both sides we get

M+5n-5n=p-5n

M=p-5n

Hence , now we have our M as dependent variable,  whose value depends on the values of p and n. One or both  of them can be independent variable/.

Please help me and my son I am confused
Agata [3.3K]

Answer:

-13p^{4} - 8p^{2} + 4p + 3

Step-by-step explanation:

I am having a little trouble reading the number.  I think 5 is the question number and not part of the problem.  I think this is the problem:

(4p - 6p^{4} - 3) - (8p^{2} + 7p^{4} - 6)  You take the opposite of everything inside the second set of parentheses.  You can think of it as multiplying through by -1

4p - 6p^{4} - 3 - 8p^{2} - 7p^{4} + 6  Now we combine like terms.  That is the numbers with the same variable p and the same power of p.

-13p^{4} - 8p^{2} + 4p + 3
