Final result :<span> (c2 - 2c - 6) • (c + 5) </span>Step by step solution : Step  1  :Trying to factor by splitting the middle term<span><span> 1.1 </span>    Factoring <span> c2-2c-6</span> 

The first term is, <span> <span>c2</span> </span> its coefficient is <span> 1 </span>.
The middle term is, <span> -2c </span> its coefficient is <span> -2 </span>.
The last term, "the constant", is <span> -6 </span>

Step-1 : Multiply the coefficient of the first term by the constant <span>  1 • -6 = -6</span> 

Step-2 : Find two factors of  -6  whose sum equals the coefficient of the middle term, which is  <span> -2 </span>.

Dr. Brown did 6 experiments at 7AM. Dr. Rachal did 8 experiments at 6PM. They both had 564 tools each. Dr. Brown used 386 and Dr
devlian [24]

Answer:

Step-by-step explanation:

Total number of tools for both = 564.

Dr Brown used 386 tools for 6 experiments.

average number of tools per experiment used by Dr Brown = \frac{386}{6}

                                               = 64\frac{1}{3}

Dr Rachal used 236 tools for 8 experiments.

average number of tools per experiment used by Dr Rachal = \frac{236}{8}

                                                = 29\frac{1}{2}

i. The number of more experiment that can be done by Dr Brown = (564 - 386) ÷ (64\frac{1}{3})

                                 = 2.7668

Dr Brown can do two more experiments.

The number of more experiments that can be done by Dr Rachal = (564 - 236) ÷ (29\frac{1}{2})

                                  = 11.1186

Dr Rachal can do 11 more experiments.

ii. Number of tools left after Dr Brown's experiments = 564 - 386

                                                            = 178

Number of tools left after Dr Rachal's experiments = 564 - 236

                                                            = 328

What is the degree measurement for angle 2+27x. Thank you to anyone that helps
HACTEHA [7]

Answer:

2+27x = 110°

Step-by-step explanation:

Since both lines are parallel, the angles are same side interior angles, which mean they both add up to 180°.

(16x+6)+(2+27x) = 180°

Move them to each side:

16x+27x = 180-6-2

43x = 172°

x = 4°

Verify:

110°+70° = 180°

Help. I’m stuck on this one skskksks
VMariaS [17]

I'm pretty sure the answer is: <u><em>h = 9</em></u>

<u><em></em></u>

<u><em>Reason:</em></u>

The question tells us that to complete the equation that represents the relationship between d and h, so for "d", its d = 1, for h, it is 9 per each "days"

from the hours.
