Anuta_ua [19.1K]
Hello,
let
t=(-4)+(-12)+(-20)+(-28)+(-36)+....=-(4+12+20+28+36+...)=-s

a_{1}=4=-4+1*8
a_{2}=12=-4+2*8
a_{3}=20=-4+3*8
a_{4}=28=-4+4*8

...
a_{18}=?=-4+18*8=140

a_{i}=-4+i*8

s=\sum_{i=1}^{18} (-4+i*8)=\sum_{i=1}^{18} (-4)+\ 8*\sum_{i=1}^{18}(i)\\\\=(-4)*18+8*(1+2+3+4...+18)\\\\=-72+\frac{(1+18)*18}{2}\\\\=-72+171=99

\boxed{\ t=-99}

Find the area of the composite figure
yuradex [85]

Answer:

The area is 189 square meter.

Step-by-step explanation:

In this figure we have one square of 7 meter sides and one rectangle of 20 meter length and 7 meter of width.

Area of a square = side²

area of a rectangle = Length × width

Area of the square = 7² = 7 × 7 = 49 meter²

Area of the rectangle = 20 × 7 = 140 meter²

Area of the composite figure = 49 + 140

                                                = 189 meter²

The area is 189 square meter.
