Answer:
Perimeter is 17.07
Step-by-step explanation:
We know that DF = EF = 5 cm, since D and E are the midpoints of AC and AB, both of which are 10 cm in length.
We need to use the Pythagorean theorem to get the length of DE.
![DE = \sqrt{5^{2} +5^{2}}=\sqrt{50} = 7.07\\](https://tex.z-dn.net/?f=DE%20%3D%20%5Csqrt%7B5%5E%7B2%7D%20%2B5%5E%7B2%7D%7D%3D%5Csqrt%7B50%7D%20%20%3D%207.07%5C%5C)
So the perimeter of DEF is 5 + 5 + 7.07 = 17.07
Answer:
x=-1-5√17/2
Step-by-step explanation:
logo((x-2)(x+2))=2
logo(x²+3x-2x-6)=2
x²+3x-2x-6=10²
x²+x-6=100
x²+x-106=0
x=-1+5√17/2
