Answer:
(B): (x - 2)/(x + 1)
Step-by-step explanation:
The numerator is x^2 + 5x - 14. That is equal to (x - 2)(x + 7).
The denominator is x^2 + 8x + 7. That is equal to (x + 1)(x + 7).
You can then eliminate (x+7) to get (x - 2)/(x + 1).
Answer:
There are 16 multiple choices and 6 short answers.
Step-by-step explanation:
Let the number of multiple choice questions be x and the number of short answer questions be y.
x + y = 22 (total number of questions)
4x + 6y = 100 (total number of points)
x = 22 - y
4(22 - y) + 6y = 100
88 - 4y + 6y = 100
2y = 100 - 88
y = 6
x + 6 = 22
x = 16
Hence, there are 16 multiple choices and 6 short answers.

The amount of stone in each sidewalk is 3/16
<h3>How to determine the amount of stone in each sidewalk?</h3>
The given parameters are
Stones = 3/4 tons
Side walks = 4
The amount of stone in each sidewalk is calculated using
Amount = Stones/Side walks
Substitute the known values in the above equation
Amount = 3/4 / 4
Evaluate the quotient
Amount = 3/16
Hence, the amount of stone in each sidewalk is 3/16

Answer:
17
Step-by-step explanation:
- midpoint means half
- Let's name side 15 as A,11 as B and 8 as C
- 0.5 of A is 0.5×15=7.5
- 0.5 of B is 0.5×11=5.5
- 0.5 of C is 0.5×8=4
- Perimeter of small triangle =A+B+C
- 7.5+5.5+4=17
