F(2)=25=5²
f(3)=125=5³
f(4)=625=55⁴
..............
So,
f(x)=(5^x)>>>>=required exponential function
19-3=16
16/8=2
2x8+3=19
The answer is 2.
8x^5\left(32\sqrt{2}x^2-\sqrt{2}x^4\right)
1) n(6;1;-1)=n(A;B;C), point A(2;9;4)=A(x₀;y₀;z₀);
2) common view for a plane according the conditions is: A(x-x₀)+B(y-y₀)+C(z-z₀)=0;
3) after substituted coordinates: 6(x-2)+(y-9)-(z-4)=0; ⇒ 6x+y-z-17=0.
Step-by-step explanation:
lenght = x + 8
width = x

then
Lenght = x + 8 = 20 + 8 = 28
Width = x = 20
