Answer: x=8 x=0
Step-by-step explanation:
Answer: 81
since it's the 4th power then you do 3x3x3x3= 81
Step-by-step explanation:
Answer:
1356 cm²
Step-by-step explanation:
Each dimension gets multiplied by 2, so the new dimensions are
changed from 2x8x7 to 6x24x21
There are 6 faces to the prism,
The area of the front and back are 6x21 = 126. There are 2 of them for a total area of 126x2 = 252 cm²
The are of the left and right sides are 24x21 = 504. There are 2 of them for a total area of 504x2 = 1008 cm²
The area of the top and bottom are 6x24 = 144, there are 2 of them for a total area of 144x2 = 288 cm²
The total surface area is 252 + 1008 + 96 = 1356 cm²
You can use the quadratic formula with it which will be easier
or simple factoring
it will be (5x-11)(7x+4)
