Answer:
your answer should be number 1
The first thing we are going to do for this case is to rewrite the expression.
We have then:
-48xyz - 24xy + 40xyz
The common factor is a term that is present in all terms of a given expression.
The following expressions are common factor:
4
8y
2xy
Answer:
A. 4
D. 8y
E. 2xy
He was off by 9.5%, you just divide 5.43 by 6 then subtract that answer from 1 and you get your percentage
does it mean that she bought 4 of the 1/3 pieces or 5/3 yards (as in four and one third)?
The figure is the right triangle DEF.
In it, E is the 90° angle, D is the corner over E (this is, DE is the vertical segment or height from the base) and F is the corner to the right of E (f, is the angle and EF is the horizontal segment or base of the triangle).
Then EF is the adjacent leg to the angle f, DE is the opposite leg to the angle f, and DF is the hypotenuse of the triangle.
Given that the angle f is 45°, you know that the triangle is isosceles (45-45-90) and then the two legs have the same length and you can use Pytagorean theorem:
DF^2 = x^2 + x^2 = 2x^2 => x^2 = (DF)^2 / 2
Taking square roots from both sides:
=> x = DF / √2 = 22 / √2 = [22√2] / [(√2)(√2)] = [22√2] / 2 = 11√2
Remember, both legs have the same length.
Answer: 11√2
