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](https://tex.z-dn.net/?f=%5Csqrt%7Bx%2B7%7D-x%3D5%5C%5C%5Csqrt%7Bx%2B7%7D%3D5-x%5C%5C%28%5Csqrt%7Bx%2B7%7D%20%29%5E%7B2%7D%3D%285-x%29%5E%7B2%7D%20%20%20%20%5C%5Cx%2B7%3D25%2B10x%2Bx%5E2%5C%5Cx-10x%3D25%2Bx%5E2-7%5C%5C-9x%3D18%2Bx%5E2%5C%5C-x%5E2-9x-18%3D0%5C%5C-1%28x%5E2%2B9x%2B18%29%3D0%5C%5Cx%5E2%2B9x%2B18%3D%5Cfrac%7B0%7D%7B-1%7D%5C%5Cx%5E2%2B9x%2B18%3D0%5C%5C%28x%2B6%29%28x%2B3%29%3D0%5C%5Cx%2B6%3D0%20%3D%3D%3D%3E%20x%3D-6%5C%5Cx%2B3%3D0%20%3D%3D%3D%3E%20x%3D-3%5C%5CChecking%5C%5C%5Csqrt%7B-6%2B7%7D-%28-6%29%3D5%3D%3D%3D%3E%5Csqrt%7B1%7D%2B6%3D7%5Cneq5%20%20%5C%5C%5C%5C%5Csqrt%7B-3%2B7%7D-%28-3%29%3D5%3D%3D%3D%3E%5Csqrt%7B4%7D%2B3%3D5%3D5%5C%5C%5C%5CSo%20%5C%5Cx%3D-3)
Answer:
2:45
Step-by-step explanation:
the tiny hand on the clock represents the hour while the long hand on the clock represents the minute(s).
that being said, the tiny hand is between 2 and 3-we can eliminate c and d.
look at the minute hand. it is on 9, which means 45
we can cross out 3:45 as the hour hand is not between 3 and 4.
this leaves us with 2:45
hope this helps :)
