Given:
A figure of a rectangular prism with length l, width w and height h.
To find:
The surface area of the rectangular prism.
Solution:
The product of twice of the length l and the width w is:
...(i)
The product of twice of the length l and the height is:
...(ii)
The product of twice of the width w and the height h is:
...(iii)
The surface area of the prism is the sum of (i), (ii) and (iii). So, the expression for the surface area is:


Therefore, the required expression is
.
Answer:
172.27 in
Step-by-step explanation:
Apply the Sine Rule
Sine Rule is given as:

c = x = ?
C = 180 - (52 + 48) = 80° (sum of triangle)
b = 130 in.
B = 48°
Plug in the values

Multiply both sides by sin(80)

172.274641 = x
x = 172.27 in. (to 2 decimal places)
Answer:
x^2 + 2x + 2.
Step-by-step explanation:
Write it in factor from:
(x - (-1 + i))(x - (-1 - i)) = 0
(x + 1 - i)(x + 1 + i) = 0
= x^2 + x + ix + x + 1 + i - ix - i -i^2
= x^2 + 2x + 1 + 1
= x^2 + 2x + 2.
Answer:
Part A: 6ml of antifreeze
Part B: 10ml of antifreeze
Step-by-step explanation:
10% of 60ml is 6ml
60/10 = 6
1/10 of 60 equals 6ml.
50% of 20ml is 10ml.
20/2 = 10
1/2 of 20 equals 10ml.
Answer:
-23
Step-by-step explanation:
h(-3) = (-3)^3 + 4
= -27 + 4
= -23
