Hello there,
If c=-2 just plug in -2 for every c you see.
(-2)²-7(-2)-8
This simplifies to
4+14-8
18-8
10
Hope this helps!

The total length in metres (this completes the question)
The total length is:
Convert mm to m
<em>The total length of the wood is 9.65 metres</em>
B=6 i believe! if you use the pythagorean theorem (a^2+b^2=c^2) then you should be able to turn 8^2 and 10^2 into 64 and 100, respectively. 100-64=36 and the square root of 36 is 6. you can plug it in by calculating 8^2 + 6^2, which equals 100! hope this wasn't too confusing XD

Answer:
Step-by-step explanation:
1. By definition, scientific notation has the following form:
Where:
<em> a</em> is a number between 1 and 10 but does not include 10.
<em> b </em>an integer.
2. When you multiply 3.25 by 7.8 the result is 25.35 and when you multiply by , you obtain , but to write ree thsult in scientific notation, the decimal point must be after the first digit. Therefore, you must move the decimal point one place to the left. So, the exponent changes from 9 to 10:
