Answer:
<em>x + x + 1 + x + 2 + x + 3 + x + 4 + x + 5 + x + 6 = 7(x + 1)</em>
Step-by-step explanation:
<u>Equations</u>
The situation can be written as an algebraic equation by setting the variables as follows:
x = first integer
x + 1 = second integer
x + 2 = third integer
x + 3 = fourth integer
x + 4 = fifth integer
x + 5 = sixth (and last) integer
The sum of all six numbers must be equal to 7 times the second number, thus:
x + x + 1 + x + 2 + x + 3 + x + 4 + x + 5 + x + 6 = 7(x + 1)

Step-by-step explanation:
Hey there!
In order to solve this problem, you need to know this:
13 pieces of wood, and 1 piece of wood=0.5 ft
Your equation would be 0.5*x=13
13/0.5=x
x=26
Your answer is 26 feet long!
Good luck! :)
Answer: B
Step-by-step explanation: How do we find the local extrema? Let f be continuous on an open interval (a,b) that contains a critical x-value. 1) If f'(x) > 0 for all x on (a,c) and f'(x)<0 for all x on (c,b), then f(c) is a local maximum value. 2) If f'(x) < 0 for all x on (a,c) and f'(x)>0 for all x on (c,b), then f(c) is a local maximum value.
<span>We all know that the interior angles of a triangle sums up to 180</span>°. To get the missing angle, we simply subtract the sum of the given angles from 180°
<span>
Similar triangles have the same measure of angles.
Triangle 1: 80°, 62° </span>→ 180 - 80 - 62 = 38°<span>
Triangle 2: 62°, 38° </span>→ 180 - 62 - 38 = 80° SIMILAR TRIANGLES<span>
Triangle 1: 29°, 47° </span>→ 180 - 29 - 47 = 104°<span>
Triangle 2: 91°, 76° </span>→ 180 - 91 - 76 = 13° NOT SIMILAR<span>
Triangle 1: 100°, 45° </span>→ 180 - 100 - 45 = 35°<span>
Triangle 2: 25°, 45° </span>→ 180 - 25 - 45 = 110° NOT SIMILAR
