Answer:
18
Step-by-step explanation:
f(x) = 2x^2
Let x = -3
f(-3) = 2 * (-3)^2
Exponents first
f(-3)=2 *9
f(3) = 18
Mike biked 10 miles in 1.5 hours. Mila bikes at the same rate too.
Therefore, she will bike x miles in 3.5 hours
(10/1.5) = (x/3.5)
You cross multiply
1.5x = 10 x 3.5
1.5x = 35
x = 35/1.5
x = 23 miles (approximately)

Answer:
≈85.43
Step-by-step explanation:
apply the binomial theorem to the square
![=(5)^{2} +2(5)(3\sqrt{2} )+(3\sqrt{2} )^{2}](https://tex.z-dn.net/?f=%3D%285%29%5E%7B2%7D%20%2B2%285%29%283%5Csqrt%7B2%7D%20%29%2B%283%5Csqrt%7B2%7D%20%29%5E%7B2%7D)
![=25+30\sqrt{2} +18\\](https://tex.z-dn.net/?f=%3D25%2B30%5Csqrt%7B2%7D%20%2B18%5C%5C)
![=43+30\sqrt{2}](https://tex.z-dn.net/?f=%3D43%2B30%5Csqrt%7B2%7D)
≈85.43
