Use the surface area formula of a rectangular prism to find the width. (I have changed it to use the same terms given in the problem).
A
=
2
(
d
w
+
h
w
+
h
d
)
Because of the given information, it is known that:
A
=
208
h
=
8
d
=
6
The width is not know, so let it keep it's variable
w
. But substitute the other values into the equation:
A
=
2
(
d
w
+
h
w
+
h
d
)
208
=
2
[
6
w
+
8
w
+
(
8
)
(
6
)
]
208
=
2
(
14
w
+
48
)
Use the distributive property to solve the right side of the equal sign:
208
=
2
(
14
w
+
48
)
208
=
28
w
+
96
112
=
28
w
112
28
=
w
4
=
w
The width is
4
.

Answer:
Perimeter = 36 cm
Step-by-step explanation:
Firstly, Check the attached picture
perimeter = 10 + 10 + 8 + 8
= 20 + 16
= 36
:)
Answer:
22°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
x + x + 136° = 180°
2x + 136° = 180° ( subtract 136° from both sides )
2x = 44° ( divide both sides by 2 )
x = 22°

Step-by-step explanation:
change x to -3 since x= -3 so it will be
(3)(2) -3(-3) + 4
6+9+4= 19
