Answer:
169 cm^2
Step-by-step explanation:
Right surface (rectangle)
A = LW = 7 cm * 5 cm = 35 cm^2
Left surface (hidden rectangle)
Bottom surface (hidden rectangle)
A = LW = 9 cm * 5 cm = 45 cm^2
Front face = back face = 2 * triangle
A = 2 * bh/2 = 2 * 9 cm * 6 cm/2 = 54 cm^2
total surface area = 35 cm^2 + 35 cm^2 + 45 cm^2 + 54 cm^2 = 169 cm^2
x < -3 1/2 or 3.5
-9x + 5 < 17
13x +25 < -1
If we add the 2 equations together, we will have
4x + 30 < 16
4x < 16 - 30
4x < -14
Divide both sides by 4
x< -14/4
b, d
20/-4 = -5
20 x (-1/4) = -5
It’s b
Answer: 3 and 5 are supplementary angles, and 1 and 4 are vertical angles.
