Sec∅ = 1/cos∅
= 1/cos(240)
= 1/cos(180 + 60)
= 1/-cos(60)
= 1/(-1/2)
= -2
Answer:
C) (3 , 2)
Step-by-step explanation:
y is greater than 2x - 7.
Note the point values (x , y). y, in this case, must be greater than x after it is simplified.
~
(3 , -2)
Plug in 3 for x, and -2 for y:
(-2) > 2(3) - 7
-2 > 6 - 7
-2 > -1
(False).
~
(4 , 1)
Plug in 4 for x, and 1 for y:
(1) > 2(4) - 7
1 > 8 - 7
1 > 1
(False).
~
(3 , 2)
Plug in 3 for x, and 2 for y:
(2) > 2(3) - 7
(2) > 6 - 7
2 > 1
(True).
~
∴ C) (3 , 2) is your answer.

40%*2=80 I hope I helped!
= (5x - 3x) + (2x - x)
= 2x + x
= 3x
Note: 1x is the same as ‘x’
1x = x
Width be X, length is X+15
area of garden = x(x+15)
area of sidewalk = x(x+15) - (x-4)(x+11) = 632
X^2 + 15X - X^2 - 7X + 44 = 632
8X = 632-44 =588
X= 73.5 >> WIDTH and LENGTH = 88.5
