Answer:
2x - 8 = 12 has the same solution as 12/x-4 = 2
Step-by-step explanation:
They both equal 10
The <em><u>correct answers</u></em> are:
90°, 180° and 270°
Explanation:
Squares have rotational symmetry at 90°. This can be found by dividing the number of degrees in a circle, 360, by the number of sides, 4:
360/4 = 90
This means that at all multiples of 90, the square will rotate onto itself. This means that 90, 180 and 270 are all correct.
Answer:
-80\112 = -5\7
we divided both numbers by 16
Answer:
x = 26, 16
Step-by-step explanation:
( x-21) ^2 = 25
Take the square root of each side
sqrt(( x-21) ^2) = ±sqrt(25)
x-21 = ±5
Add 21 to each side
x-21+21 = 21±5
x = 21±5
x = 21+5 and x = 21-5
x = 26, 16
