X + (x + 2) + ( x + 4) + (x + 6)
-----------------------------------     = 15
                   4

4x + 12
---------    = 15
    4

Multiply by 4 on both sides

4x + 12 = 60
subtract 12 from both sides
4x = 48
divide by 4 on each side
x = 12
x + 2 = 14
x + 4 = 16
x + 6 = 18

Before offering imaging programs, practitioners need to be aware of the reasons why exercise participants are doing it.

<h3>Define imagery in sports.</h3>

When we use imagery, we simulate an actual situation in our minds rather than actually going through it. It differs significantly from daydreaming or simply thinking about anything because it is a cognitive activity that is consciously used by an athlete or exerciser to accomplish a certain task.

In this study, an analysis of secondary data from a recently published randomized controlled trial. In a community-based, group-mediated physical activity intervention for sedentary people 50 and older, the Active Adult Mentoring Program (AAMP) tested the effectiveness of peer volunteers as delivery agents. The AAMP was built on the social-cognitive and self-determination theories, and mentors were trained to lead discussions in groups that would help reinforce key ideas from both theories.

The adaptability of images makes it useful at different times and in varied settings. Athletes employ imagery most frequently right before a competition or during practice, but they do so during the entire season, including the off-season. Similar to how it's reported by athletes, visualization is frequently used before an activity session. For example, it would be more effective for a swimmer to mentally practice her race start by adopting the proper position on the starting block at the swimming pool, as opposed to sitting on a chair at home. Both types of people will typically imagine within the sport and exercise environment where the benefits of this technique are maximized.

I WILL MARK BRAINIEST<br> PLEASE HELP ASAP ITS DUE
Daniel [21]

Answer:

A) 1 : 4

B) 1 : 2

C) Base of M = 10 units

Step-by-step explanation:

A)

The ratio of the area of triangle M to triangle N

\frac {40}{160}= \frac{1}{4} = 1 : 4

B)

The ratio of the side lengths of triangle M to triangle N

\sqrt{ \frac {40}{160}} = \sqrt{\frac{1}{4}} \\\\={\frac{1}{2}} \\\\=1 : 2

C) Let the base of triangle M be b units.

\sqrt{ \frac {40}{160}} = \frac{b}{20}\\\\\frac{1}{2}=  \frac{b}{20}\\\\2b = 20\\\\b = \frac{20}{2} \\\\b = 10
