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)
-2 - 3 = -5
The answer is negative 5.

Answer: The first radio button choice 8/3 * m^8
Steps:
120 (m^ 16) / 45 (m^8) =
120/45 * (m^16)/(m^8) =
Simplify 120/45 (15 or 5 *3 divides each). Since base "m" is same in both terms simply subtract exponents.
8/3 ( m^(16 - 8)) =
8/3 * m^8

Answer:
x= 17/8
Step-by-step explanation:
6x− 5/2=2x+6
Step 1: Simplify both sides of the equation.
6x+−5/2=2x+6
Step 2: Subtract 2x from both sides.
6x+−5/2−2x=2x+6−2x
4x+−5/2=6
Step 3: Add 5/2 to both sides.
4x+−5/2+5/2=6+5/2
4x=17/2
Step 4: Divide both sides by 4.
4x/4=17/2/4
x=17/8
