Answer:
152
Step-by-step explanation:
We know that the total surface area of a cuboid is the sum of the surface area of all six of its faces.
We also know that each opposing side has the same surface area. Thus the total surface area is equal to:
()
Answer:
186
Step-by-step explanation:
Step-by-step explanation:
10. 8a - 12b
11. d^8
12. 3y^3
13. 4a+b
14. 11x-3
15. 2a^2+2ab
16. 2x^3+x
17. 4(a+2)
18. 3m(m-3)
You have to multiply by the complex conjugate so that you can clear the radical from the denominator.
Once you do the multiplication simplify the radical. There's still a common factor in -54, -18, & 75 so divide all those by 3.
Answer:
The value of n is 6.
Step-by-step explanation:
Given that these 2 triangles form a square so we can assume that all sides are same. Then, we have to apply Pythagoras Theorem, a² + b² = c², where a, b are sides and c is hypotenuse :
n² + n² = (6√2)²
2n² = 6² × (√2)²
2n² = 72
n² = 72 ÷ 2
n² = 36
n = √36
n = 6
