Answer:
Yes
Step-by-step explanation:
using distributive properties,
(3x+1)(4x-5) = 3x(4x-5) + 1(4x-5)
=> 12x^2 - 15x +4x - 5
=> 12x^2 - 11x - 5

Answer:
x = 9.5
x = 9 1/2
x = 19/2
All answers are the same, just different ways of denoting it.
Step-by-step explanation:
-4 + 5x - 7 = 10 + 3x - 2
Simplify both sides, by combining like terms
-4 + 5x - 7 = 10 + 3x - 2
-11 + 5x = 8 + 3x
Inverse operations
-11 + 5x = 8 + 3x
+11 +11
5x = 19 + 3x
-3x -3x
2x = 19
/2 /2
x = 9.5
The formula to find the volume of a pyramid is: V=lwh/3 therefore:
V = lwh/3
38 = 6(6)(h)/3
114 = 36(h)
h = 3.17 (2 dec. places)
The height of the square pyramid is 3.17cm.
