M(x) = 5x + 4 n(x) = 6x - 9
Part 1 (m + n)(x) = 5x + 4 + 6x - 9
= 11x - 5
Part 2 (m * n)(x) = (5x + 4)(6x - 9) = 30x^2 - 21x - 36
Part 3 m[n(x)] = 5(6x - 9) + 4
= 30x - 45 + 4
= 30x - 41
Answer:
X = 33°

Answer:
h = 24 cm
Step-by-step explanation:
volume of water in the cylinder = volume of water in the rectangular base container
But ,
volume of cylinder = 
h
where: is the radius and h is the height.
volume of cuboid = length x width x height
= l x w x h
So that;

h = l x w x h
But, r =
=
= 9 cm, height of cylinder = 28 cm, length = 27 cm, width = 11 cm,
=
.
Thus,
x
x 28 = 27 x 11 x h
x 81 x 28 = 27 x 11 x h
7128 = 297h
h = 
= 24
h = 24 cm
The depth of the water in the container is 24 cm.
Step-by-step explanation:
B²=a²+c²
12²=4.2²+c²
144=16.4+c²
144-16.4=c²
127.6=c²
√127.6=√c²
11.3=c
