3(r-6)+2=4(r+2)-21 find the value of x and show steps

MAXImum [283]

3(r-6) +2 = 4(r+2) -21
3r - 6r +2 = 4r +8 -21
-3r +2 = 4r -13
2 = 7r -13
15 = 7r
r = $\frac{15}{2}$
r = 7.5

Liza y Abby planean extender sus mantas en un parque para un picnic con sus amigos. El parque está lleno de gente, así que extie

Margarita [4]

Answer:

Step-by-step explanation:

The question in English is basically find the area of the pink and blue area shown. The image is attached. This is Liza and Abby's blanket spread and we want the area of the whole shown.

Solution:

We want area of pink rectangle PLUS the blue region, which is a sum of lower rectangle and top triangle (if we cut it in this way).

First, area of pink rectangle:

Area = length * height

Area = 5 * 5.7

Area = 28.5

Now, the blue region, if broken down, lower portion is rectangle and upper portion is a triangle (we DISREGARD the overlapping region, of course!)

Lower Rectangle Area = length * height = 4 * 2 = 8

Upper triangle Area = 0.5 * base * height = 0.5 (4) * (6-2) = 0.5 * 4 * 4 = 8

So, blue region area = 8 + 8 = 16

Total Area = 28.5 + 16 = 44.5 sq. ft.

A ladder leans against a window in a two-story building. the window is 16 feet off the ground. the base of the ladder is 12 feet

Kitty [74]

A^2 + b^2 = c^2
16^2 + 12^2 = c^2
256 + 144 = c^2
400 = c^2
sqrt 400 = c
20 = c <== the ladder is 20 ft long
