A chemist is researching different sustainable fuel sources. She is currently working with benzene, which must be in liquid form

for her to successfully conduct her
research. The boiling point of benzene is 176° F, and the freezing point is 42° F

Part A: Write an inequality to represent the temperatures the benzene must stay between to ensure it remains liquid. (2 points)

Part B: Describe the graph of the inequality completely from Part A. Use terms such as open/closed circles and shading directions. Explain what the solutions to the
inequality represent. (4 points)

Part C: In February, the building's furnace broke and the temperature of the building fell to 20° F Would the chemist have been able to conduct her research with
benzene on this day? Why or why not? (4 points)

Side 2: 20 feet

Side 3: 22 feet

Just number 4 please hurry and help meeee
Hoochie [10]

Answer:

C D H

Step-by-step explanation:

The best way to tackle this problem is to put each answer into the equation and evaluate the equation.

for example

-(-3.9) + 6 >= 10

3.9 + 6 >= 10

9.9 >= 10 .this is not true!

be very careful with the signs and evaluate each answer.

What are the solutions to the quadratic equation below?
Luden [163]

Using factorization method;

x²+13x+40=0

x²+13+40

Find two numbers that you can add together to give the co-efficient of variable x. (I.e 13 for this question). Also, you'll find two numbers that you can multiply with each other to give you the whole number as an answer. (I.e 40 in this question). The two numbers must be the same (i.e the two numbers that will be added to give the co-efficient of x and the two numbers that will be multiplied to give the whole number must be the same two).

The two numbers are +5 and +8

The equation will therefore be = x²+5x+8x+40

You'll then factorize (I.e use a common factor of both values to bracket them)

x(x+5)+8(x+5)

(x+8)(x+5)

x is therefore (x+8=0) or (x+5=0)

x=(x=0-8) or (x=0-5)

x= -8 or x= -5
