C=1/6 of x
D=55/1/2
1/6 of 111/2=110.167
55.08
=55 inches
If that is a rhombus as it says it is, then the diagonals are perpendicular to one another, meaning where they meet, they form right angles. Therefore, angle x is a 90 degree angle.
X < -40.5
To find this, here are the steps:
Combine like terms like so:
-4x - 49 > 113
Then, begin to isolate the variable x by adding 49 to both sides leaving you with:
-4x > 162
Then divide by negative four. Don’t forget, dividing by negatives switches the way the sign points so your final product will be:
x < -40.5
Hope this helps!
(18-2X)(8-2X)
Take each side and subtract 2X, then multiply them together for the area.
