Answer:
x +4
Step-by-step explanation:
The trinomial x² +8x +16 is a perfect square trinomial, so factors as ...
x² +8x +16 = (x +4)²
Assuming the side length is one of the factors of the given area, it will be ...
side length = (x +4)
After reading through the story problem, I ended up with this equation:
(35-2)(x+.5) =?
or
(35-2)(10+.5)=?
Explanation:
He sells 35 books for usual weeks. Since he is selling his books at $.50 more his average number of copies decreased by 2.
35-2 = 33
Next, we know that he adds $.50 for his price for each copy. If the price is $10 per copy than it looks like this:
$10+$.50= 10+.5
or if the price is not $10 it will be
$x+$.5= x+.5
Answer:
2) 0.45 3)1.67 4)8/125
Step-by-step explanation:
1000g=1kg
450g=0.45kg
1 4/6 =10/6
10/6=1.67
0.64=64/1000
64/1000=8/125
-5 is essentially -1·5
Order of operations says to do exponents first, so without parentheses -5², you would square first then multiply by -1, leaving you with an answer of -25.
However, parentheses comes before exponents in order of operations, so with parenthesis (-5)² would be 25.
