How is finding the factors of a number different from finding the prime factorization of a number.
mario62 [17]
When finding factors of a number, you are just finding numbers that can factor into it. When finding the prime factorization, you are narrowing down the factors to the smallest factored numbers.

Ex:     40                 •The bolded numbers are the most simplified factors.
         /    \
       8     5
     /   \
   4    2          The prime factorization of 40 is 5 x 2^3.

WILL GIVE BRAINLIEST if you explain your answer!!
mr Goodwill [35]

Answer:

x=-3

Step-by-step explanation:

You need to delete the root by ^2. First you need to leave it alone

\sqrt{x+7}-x=5\\\sqrt{x+7}=5-x\\(\sqrt{x+7} )^{2}=(5-x)^{2}    \\x+7=25+10x+x^2\\x-10x=25+x^2-7\\-9x=18+x^2\\-x^2-9x-18=0\\-1(x^2+9x+18)=0\\x^2+9x+18=\frac{0}{-1}\\x^2+9x+18=0\\(x+6)(x+3)=0\\x+6=0 ===> x=-6\\x+3=0 ===> x=-3\\Checking\\\sqrt{-6+7}-(-6)=5===>\sqrt{1}+6=7\neq5  \\\\\sqrt{-3+7}-(-3)=5===>\sqrt{4}+3=5=5\\\\So \\x=-3

The temperature is 78 °F at 2:00 in the afternoon. If the temperature drops 4 °F every hour after that, what is the temperature
Galina-37 [17]

Answer:

The answer to your question is: 54°F

Step-by-step explanation:

Data

Ti = 78°F

Initial hour = 2:00

Temperature drops 4°F every hour

Temperature at 8:00 = ?

Process

                      2:00                  

                       3:00             78-4 =     74°F

                      4:00              74-4 =      70°F

                      5:00              70-4 =      66°F

                      6:00              66-4 =      62°F

                       7:00             62-4 =     58°F

                      8:00              58-4 =      54°F
