Step-by-step explanation:

Original Equation:

8x+3(x+5)-5(x-4)

Multiply the number behind bracket one(x+5) and bracket two(x-4)

So it's going to be;

8x+3x+15-5x+20

We have +20 because when you multiply two negative numbers it becomes a positive.

So now we will Combine Like Terms

11x+3x-5x+15+20

Then you will add

11x-5x+35

6x+35

So when you are done this will be the final answer will be;

6x+35

Solve the equation 3p (3p - 8) - 8 = 9p ( p - 3 + 4

pentagon [3]

Answer:

$p= \frac{-8}{33}$

Explanation:

Given:

$3p (3p - 8) - 8 = 9p ( p - 3 + 4)$

To Find:

Value of p=?

Solution:

Before solving this equation, we will use the method of BODMAS which states that we first solve the Bracket then Off then Division then Multiplier then addition and at last subtraction.

Now we will solve the both right and left hand side of the equation

$3p (3p - 8) - 8 = 9p ( p - 3 + 4)$

$9p^2-24p-8=9p^2+9p$

Gruoping the like terms we get,

$9p^2-9p^2-24p-9p=8$

After solving the both right hand and left hand side of the equation

$-33p=8$

And we get the value of p as

$p= \frac{-8}{33}$

If anyone could answer this for me I would very much appreciate it

Answer:

a3 = 45

Step-by-step explanation:

a1 = 20

an = a(n-1) *3/2 where n is the term number

a2 = a(2-1) *3/2

a1 *3/2

We know a1 = 20

a2 = 20*3/2 = 30

a3 = a(3-1) *3/2

= a2 *3/2

We know a2 = 30

= 30*3/2 = 45

Brackets
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

Left to Right

Algebra I

Coordinates (x, y)
Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (-2, -1)

Point (-8, 11)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{11+1}{-8+2}$
[Fraction] Add: $\displaystyle m=\frac{12}{-6}$
[Fraction] Divide: $\displaystyle m=-2$
