Answer:
9.936
Step-by-step explanation:
In(x+5)*x=5
ln(x^2+5x)=5
e^5=x^2+5x
148.4131=x^2+5x
x^2+5x-148.4131=0
x is 9.936 because logs can't be negative

V= a^3
So in this case V= 6^3
V= 216
Yes 8 is a multiple of 8 because 1x8=8
Answer:
424 cm²
Step-by-step explanation:
The figure is composed of a square and a trapezium on top
A of square = 18² = 324 cm²
A of trapezium =
h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 8, b₁ = 18 and b₂ = 7 , then
A = 0.5 × 8 × (18 + 7) = 4 × 25 = 100 cm²
Area of hexagonal park = 324 + 100 = 424 cm²
