Hello!
To find the perimeter of any rectangle, use the formula P = 2l + 2w.
In this formula, l is the length and w is the width. Given that the width is 2x + 9 and the length is x + 4, we can find the perimeter.
P = 2(x + 4) + 2(2x + 9)
P = 2x + 8 + 4x + 18
P = 6x + 26
Therefore, the perimeter of the rectangle is 6x + 26.
Answer:
Friday: 45º
Saturday: 23º
Sunday: 30º
Monday: 65º
Step-by-step explanation:
Given that the temperature in Columbus, Ohio, on Monday is 35 degrees warmer than it was on Sunday, while Saturday's temperature was 7 degrees cooler than Sunday's and, at 45 degrees, Friday's temperature was 22 degrees warmer than Saturday's, to determine the temperature of each day the following calculations must be carried out:
Friday: 45º
Saturday: 45º - 22º = 23º
Sunday: 23º + 7º = 30º
Monday: 30º + 35º = 65º

Well looking at the information in triangle ABC you know
Angle B + Angle C = 180 - 144
so Angle B + Angle C = 36
since the triangles are similar let angle M = x
then Angle C = 2x and angle B = angle M but the similarity postulate
so form an equation
2x + x = 36
solve for x
Hope it helps
Answer:
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
In a parallelogram opposites sides are parallel and congruent
so
In this problem
---> by opposite sides
substitute the given values
