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)
23 mm, 20mm, 13mm sides: No equal sides and No equal angles are characteristics of a Scalene Triangle.
62,72,46 angles : All angles are less than 90°, this means that the triangle is an acute triangle.
Based on the above information the triangle is an ACUTE SCALENE TRIANGLE.
Answer:
the answer is the last one D: [-2, infinity)
R: [-1, inifnity)
Since 1 hour = 60 minutes,
Hence, 120 miles/hour = 120 miles / 60 minutes = 2 miles/minute
X=12
(10(12)-20) = 120-20 = 100
(6(12)+8) = 72+8=80
100+80 = 180
