Answer:
8+7d
Step-by-step explanation:
So forest you combine like terms
4+4=8
There are no longer any like terms so your finished product is 8+7d
Question 1:
The answer is A: Sam.
His table is the only one that follows the conditions set in the question.
Question 2:
Choosing two points; (0, 14) and (4, 10)
Slope (m) =

= -1
Thus, equation,


I'm getting that for my equation of the line, so my best guess is that the answer is C.
The reason I got my answer is probably because I made a calculation mistake somewhere. If you use my methods, you should arrive at the correct answer.
The answer is C. ( I believe )
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)
The sum of two consecutive integers is -23.
Let the larger number = x
smaller number = x - 1
Sum = -23
=> x + x - 1 = -23
=> 2x - 1 = -23
=> 2x = -23 + 1 = -22
=> x = -22/2
=> x = -11
Larger number is -11
