Step-by-step explanation:
question number 2 first part X + 2 is equal to 7 .. x is equal to 7 - 2x is equal to 5 ..second part 3 x minus 1 is equal to 3 x is equal to 23 - 1 = 3x=24 x=24÷3=x=8ans
Answer:
The binomial theorem allows you to write out the expansion of your polynomial immediately. (I feel like this is good enough)
Step-by-step explanation:
<em>It also allows you to answer such questions as:</em> "What is the coefficient of x20 in (1+x)100?" Its generalization to non-integer exponents allows you to get the expansion of (1−x)−1/2. There are all sorts of reasons.
Hi!
We can use PEMDAS to solve this.
3.5(5.8-7.09)
Parentheses
3.5 x -1.29
Multiplication
-4.51500
The answer is <span>-4.51500</span>
Hope this helps! :)
