Answer: -1
Step-by-step explanation:
-8 (-8x - 6) = -6x - 22
distribute
64x + 48 = -6x -22
get rid of the smallest x by adding 6x to both side
70x + 48 = -22
minus 48 to both sides
70x = -70
divide both side by 70
x = -1
Answer:
easy peasy
Step-by-step explanation:
u see,
the height of the airplane from the ground is 314m
but with the tower's horizontal plane, it would be
=> altitude of aircraft - height of tower
=> 314 - 70 = 244 m
now in the ABC,
using the ratio of sine,
sin 16 = AB/AC
=> 0.275 = 244/AC
=> AC = 244/ 0.275
=> AC = 887.9...
=> AC = approx. 886 meters
The final answer is (-25)
Answer:
d.)
Step-by-step explanation:
Answer:
Area of the square is 2916
.
Step-by-step explanation:
Let the breadth of the rectangle be represented by w. So that;
length of rectangle = 5w
Area of rectangle = length x breadth
= 5w x w
1620 = 5
divide through by 5 to have,
= 324
w = 
= 18
Thus, the breadth of the rectangle is 18 m.
length = 5 w = 5 x 18
= 90 m
The length of the rectangle is 90 m.
Perimeter of the rectangle = 2(l + w)
= 2( 90 + 18)
= 216 m
Perimeter of a square = 4l
where l is the length of its side.
Given that the perimeters of the rectangle and square are equal, then;
4l = 216
l = 
= 54
length of the side of square is 54 m.
Therefore,
Area of square = 
= 
= 2916
Area of the square whose perimeter is equal to that of the rectangle is 2916
.
