Step-by-step explanation:
The dimensions of the cuboid are 5 cm, 7 cm and 9 cm.
The formula for the surface area of the cuboid is as follows :
![A=2(lb+bh+hl)](https://tex.z-dn.net/?f=A%3D2%28lb%2Bbh%2Bhl%29)
We have,
b = 9 cm, l = 7 cm and h = 5 cm
So,
![A=2(9\times 7+9\times 5+7\times 5)\\\\A=2\times 143\\\\A=286\ cm^2](https://tex.z-dn.net/?f=A%3D2%289%5Ctimes%207%2B9%5Ctimes%205%2B7%5Ctimes%205%29%5C%5C%5C%5CA%3D2%5Ctimes%20143%5C%5C%5C%5CA%3D286%5C%20cm%5E2)
Jamie forgets to multiply 143 by 2 as the formula for surface area contains 2 as well.

Answer:
Step-by-step explanation:
3+√5 is a root.
so 3-√5 is also a root
or (x-(3-√5)) is also a factor of f(x)
18/30 simplifies into 6/10 which then is put in decimal form of 0.6
Alright, so we plug (-2) in for x. (-2)^2 =4, and we can plug that in as 4(4)+(-2)+5. Next, 4*4=16, so we get 15+(-2)+5. After that, we get 15-2+5=18
