It is a rectangle. The side lengths are not equal so it cannot be a square.
To solve, just think, what times 4 equals 12?
4*3 = 12
Therefore, multiply both sides by 3.
3*3 = 9 and 4 *3 = 12
9/12 is the final answer
Step-by-step explanation:
L.H.S
tanA * cosecA
=sinA/cosA * 1/sinA
now cancel sinA and sinA
then,
1/cosA
= secA
= RHS
hence proved
First lets write out the equation:
-8x + 2x - 16 < -5x + 7x
Lets collect the x values
-6x - 16 < 2x
-8x - 16 < 0 (subtract both sides by 2x to get all the x's on one side)
-8x < 16 ( add both sides by 16 to get all the x's alone)
x < -2 ( divide both sides by -8 to get what just x is)
So x < -2
<span>2x+y=8
2x+x-7=8
3x=15
x=5
y=5-7
y=-2</span>
