Answer:
<h3>2</h3>
Step-by-step explanation:
Given the expression -3-(-5)
This is also expressed as;
-3(-5)
= -3 + 5 (The product of two negative sign gives a positive sign)
= 5 - 3
= 2
Hence the result of the expression is 2
I guess you are asking to find the sum of the first 8 terms. If so, then:
Sum = a₁(1-rⁿ)/(1-r), where a₁ is the 1st term, r=common ratio and n=number of terms:
the 1st term a₁ =3
common ratio r = - 2 (since -6/3 = - 2, and 12/-6 = - 2, etc.)
Sum = 3[(1- (-2)⁸]/(1-2) = 3(1- 256)/(1/2)
Sum = -1530

Follow the PEMDAS order of operation:
- P = Parenthesis
- E = Exponents
- M = Multiplication
- D = Division
- A = Addition
- S = Subtraction
<em>You do these steps in the order for which the equation comes. For example, start with the exponents if there are not any parentheses.</em>

To solve for X you must get x by itself so let's get started
-4x+13=6x-7
subtract 13 from both sides
-4x=6x-20
subtract 6x from both sides
-10x=-20
divide both sides by -10
x=2
to check if this is correct plug in x into original equation
-4 (2)+13=6 (2)-7
-8+13=12-7
5=5
answer x=2 holds true :)
