Answer:
Total surface area of cube = 294 cm²
Step-by-step explanation:
Given:
Perimeter of cube = 84 cm
Find:
Total surface area of cube
Computation:
Perimeter of cube = 12 x side
84 = 12 x side
Side = 7 cm
Total surface area of cube = 6(a)²
Total surface area of cube = 6(7)²
Total surface area of cube = 294 cm²

log6 [x. (2x-7)]=log6 (6^2)
x. (2x-7)=36
2x^2-14x-36=0
2x +4
x -9
(2x+4)(x-9)=0
x= -2
x=9
