Answer:
![\large\boxed{b=0}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7Bb%3D0%7D)
Step-by-step explanation:
![4b+6=2-b+4\qquad\text{combine like terms}\\\\4b+6=(2+4)-b\qquad\text{add}\ b\ \text{to both sides}\\\\5b+6=6\qquad\text{subtract 6 from both sides}\\\\5b=0\qquad\text{divide both sides by 5}\\\\b=0](https://tex.z-dn.net/?f=4b%2B6%3D2-b%2B4%5Cqquad%5Ctext%7Bcombine%20like%20terms%7D%5C%5C%5C%5C4b%2B6%3D%282%2B4%29-b%5Cqquad%5Ctext%7Badd%7D%5C%20b%5C%20%5Ctext%7Bto%20both%20sides%7D%5C%5C%5C%5C5b%2B6%3D6%5Cqquad%5Ctext%7Bsubtract%206%20from%20both%20sides%7D%5C%5C%5C%5C5b%3D0%5Cqquad%5Ctext%7Bdivide%20both%20sides%20by%205%7D%5C%5C%5C%5Cb%3D0)
A = 1/2bh...for h
multiply both sides by 2
2A = bh
now divide both sides by b
(2a)/b = h
Hi,
So we have g(x) = 4√(x). We're looking for g(45). Think of it like this: whatever number is in the place of x in g(x), just place that number AS x.
Therefore, we have :
g(45) = 4√(45) ⇒ (4) × (√(45)) ⇒ (4)(3√(5)) = 12√(5).
-Hope this helps!
8 x 4 x 2 = 64
Therefore the volume of the pond is equal to 64m³
