Just subsitute 6x-11 for y in the second equation
-2x-3(6x-11)=-7
-2x-18x+33=-7
-20x+33=7
subtract 33 from both sides
-20x=-40
multiply -1
20x=40
dividede by 20
x=2

then subsitute
y=6x-11
y=6(2)-11
y=12-11
y=1

x=2
y=1

\left \{ {{y=6x-11} \atop {-2x-3y=-7}} \right. \ \ \ | substitute\ first\ equation\ into  \ the\ second\\\\
-2x-3(6x-11)=-7\\\\
-2x-18x+33=-7\\\\
-20x+33=-7\ \ \ | subtract\ 33\\\\
-20x=-40\ \ \ | divide\ by\ -20\\\\
x=2\\\\
y=6x-11=6*2-11=12-11=1

qaws [65]

Answer:  4π/15, 4π/3 and 28π/15 (in radians)

Step-by-step explanation:

sec 5\theta/4 =2

Recall that sec \theta = 1/cos \theta

1/cos (5\theta/4) =2

cos (5\theta/4) =1/2

Cos^{-1} \frac{1}{2} = 5\theta/4

This implies that

\mp60+360n=5\theta/4

\theta=4/5(\mp60+360n)= \mp48+288n

When  n=0, \theta=48

When  n=1, \theta=240, 336

Therefore the values of \theta between 0 and 2π are 48, 240 and 336. (All in degrees)

48 degrees= 4π/15 rad

240 degrees =4π/3 rad

336 degrees = 28π/15 rad

Answer:

divide the figure into two parts.

area of square = side²

area of square =12²

area of square =144

area pf trapezium =1/2×(a+b)×h

area of trapezium =1/2×(12+6)×12

area of trapezium =108

area of polygon=144+108=252 unit²
