Answer:
p = -14
Step-by-step explanation:
5/7p - 2/7p + 12 = 6
Combine like terms
3/7 p +12 = 6
Subtract 12 from each side
3/7p + 12-12 = 6-12
3/7p = -6
Multiply each side by 7/3
7/3 * 3/7p = -6*7/3
p = -14

Answer:
AOB = 55°
BOC = 87°
COD = 130°
AOD = 88°
Step-by-step explanation:
AOB = a°
= 55°
BOC = b°
= 87°
COD = c°
= 130°
AOD = 360°-AOB-BOC-COD
= 360°- a° - b° - c°
= 360° - 55° - 87° - 130°
= 88°

Answer:
Step-by-step explanation:
(B) 16.5π
<u>Explanation:</u>
The shape given is a cylinder
The height, h of the cylinder = 4cm
Diameter of the cylinder = 3cm
Radius, r = 1.5 cm
Surface area of cylinder, A = ?
We know:
Surface area of cylinder = 2πrh + 2πr²
Therefore, the surface area would be 16.5π
