Answer:
38
Step-by-step explanation:
Given that,
x = -4
f(x)=x² - 4x +6
so,
f(-4)= (-4)² - 4 . (-4) +6
=16 +16 +6
= 38

<em>Square tiles, design, width, long, area, inches
</em>
For this case we have square tiles. Then, for a certain design, 8 square tiles of width and 8 square tiles of length were placed, knowing that each square tile has an area of 1 square inch. We want to know Julia's design area.
So, if each square tile used to make the design has an area of 1 square inch, then it is 1 inch wide and 1 inch long each.
The area of a square tile is given by:
So if the and,
- If the design has 8 square tiles long, then the design length is inches
- If the design has 8 square tiles in width, then the width of the design is
Thus, the design area is given by the area of a square:
Answer:
The design area is 64 square inches
To start, set up and equation using what you know.
(5/6) / (a/b) = (1/4)
Then, you need to isolate a/b. To do this multiply both sides by a/b and then divide by 1/4
5/6 = (a/b) (1/4)
(5/6) / (1/4) = (a/b)
Next, simplify the left side. To do this, take the inverse of 1/4 (which is 4) and multiply by 5/6 (this is also know as 'flip the second guy and multiply').
(5/6) • 4 = a/b
20/6 = a/b
Lastly, simplify to get the final answer.
10/3 = a/b
