Answer:
90 because it is the mean
Answer:
Step-by-step explanation:
-0.59x+0.29=7.2
-0.59x+0.29-0.29=7.2-0.29
-0.59x=7.2
divide both sides by -0.59
x=−
11.7118644
that can be rounded to x= -11.7
5+620=728-72=*8%fc per second
It should open up because the a which is 4 is positive
Answer:
The height of the projection will be (x - 5) feet.
Step-by-step explanation:
A projector displays an image on a wall. The area (in square feet) of the rectangular projection can be represented by (x² - 8x + 15).
Now to get the width and the height of the rectangular projection we have to factorize the expression (x² - 8x + 15).
Here, (x² - 8x + 15)
= x² - 3x - 5x + 15
= (x- 3)(x - 5)
Now, if the height of the projection is less than its width then, the height of the projection will be (x - 5) feet. (Answer)
