Answer:
Step-by-step explanation:
The surface area of a rectangular prism has six sides so you must find the sum of the areas of all sides.
A=2xy+2xz+2yz
A=2(xy+xz+yz) you have x,y,z as 3,2,4 so
A=2(3(2)+3(4)+2(4))
A=2(6+12+8)
A=2(26)
A=52 cm^2

Answer:
3.4
Step-by-step explanation:
5t+5/4-1=4t-3/5. cross multiply over the bracket
(5t+5)5=(4t-3)(4-1)
25t + 25 = -16t -4- 12 - 3
Combine the like terms
25t - 16t +4t = -4-12-3-25
13t = - 44
Divide both sides by 13
3.38
3.4 approximately
