Answer:
6
Step-by-step explanation:
divide both sides of the equals by 5 to get p on its own
5p divided by 5 = p
30 divided by 5 = 6
Step-by-step explanation:
(5x+18) - (3x+12)
5x+18=3x+12
5x-3x=2x
18-12=6
2x+6

Answer:
B. 14 m sq.
Step-by-step explanation:
Area for a triangle
A = W times H times 1/2
4 times 7 = 28
28/2 = 14
The total surface area of a regular tetrahedron is calculated through the equation,
SA = (sqrt 3) x a²
Substituting the known value,
SA = (sqrt 3) x (10 cm)² = 173.20 cm²
Its volume is obtained by,
V = ((sqrt 2)/ 12) x a³
V = ((sqrt 2) / 12) x (10 cm)³ = 117.85 cm³
Thus, its surface area and volume are 173.20 cm² and 117.85 cm³, respectively.
