Answer:
4.817+9.099+17.008=30.924
484.603-48.198=436.405
Estimation 5+9+17=31
485-48=437
Just round each decimal to the nearest whole number and add or subtract
Answer:
x = 8, y = ![8\sqrt{2}](https://tex.z-dn.net/?f=8%5Csqrt%7B2%7D)
Step-by-step explanation:
![a^2+b^2=c^2](https://tex.z-dn.net/?f=a%5E2%2Bb%5E2%3Dc%5E2)
Both 8 and x sides are congruent so they're equal.
Add 64 + 64.
Square root 128
![c^2=8\sqrt{2}](https://tex.z-dn.net/?f=c%5E2%3D8%5Csqrt%7B2%7D)
Final answers: x = 8, y = ![8\sqrt{2}](https://tex.z-dn.net/?f=8%5Csqrt%7B2%7D)
Answer:
2
Step-by-step explanation:
where both lines intersect
therefore 2 and 5 are the two solutions
