Answer: 84
Steps:
1. Find distance between (-8,-6) and (4,-6) using distance formula:
√ (4 - (-8))^2 + ((-6) - (-6))^2
√ (12)^2 + (0)^2
√ 144 + 0
√ 144
12
2. Find distance between (1,2) and (8,2) using distance formula:
√ (8-1)^2 + (2-2)^2
√ (7)^2 + (0)^2
√ 49 + 0
√ 49
7
3. Multiply found values to find area
A = l x w
A = 12 x 7
A = 84

Answer:
The somatic nervous system is the part of the peripheral nervous system that is responsible for carrying motor and sensory information both to and from the central nervous system (CNS).
Explanation:
The primary function of the somatic nervous system is to connect the central nervous system to the body's muscles to control voluntary movements and reflex arcs. Information taken in by sensory systems is transmitted to the central nervous system. The CNS then sends signals via the nerve networks of the somatic system to the muscles and organs.
Think about it. 65 mph means you go 65 miles in one hour, so in 2 hours you go 65×2 miles, in 3 hours you go 65×3 miles, and in 3.5 hours you go 65 × 3.5 miles.

Protective systems are methods of protecting workers from cave-ins of material that can fall or roll into an excavation, or from the collapse of nearby structures. As mentioned in earlier chapters, if an excavation is less than 5 feet deep, OSHA does not require a protective systems unless the competent person sees signs of a potential cave-in. (It is important to remember that a wall collapse in a trench four and 1/2 feet deep can still have serious results!) For trenches between 5 feet and 20 feet deep, shoring and sheeting, shielding, sloping and benching are all acceptable protective measures. It is up to the planners of the construction project and the competent person on site to determine which systems will work best. If an excavation is greater than 20 feet deep, a registered professional engineer must design the protective system.
Shoring systems are structures of timber, mechanical, or hydraulic systems that support the sides of an excavation and which are designed to prevent cave-ins.Sheeting is a type of shoring system that keeps the earth in position. It can be driven into the ground or work in conjunction with a shoring system. Driven sheeting is most frequently used for excavations open for long periods of time. Another type of sheeting, in which plates or shoring grade plywood (sometimes called Finland form) is used in conjunction with strutted systems such as hydraulic or timber shoring. These strutted systems are also referred to as active systems. The most frequently used strutted system involves aluminum hydraulic shoreswhich are lightweight, re-usable and installed and removed completely from above
