Answer:
D
Step-by-step explanation:
We find the area of a rectangle by multiplying the lengths of both the sides <em>(length and width).</em>
- One side given is
- Another side given is
Multiplying these 2 will give us the expression for the area of the rectangle <em>(we use distributive property given by 
in this problem to multiply)</em>
Area = 
<em>Now combining like terms and rearranging, we have:</em>
<em>
</em>
Answer choice D is right.
The area of CEF will be calculated as follows:
The ratio of (BE+FD):EF is:
3:2
But the area of BDC=1/2ABCD
thus
BDC=1/2*100=50 in
hence the area of CEF will be:
(fraction of CEF)×(Area of BDC)
fraction of CEF=2/5
hence the area will be:
2/5×50
=20 in²
All angles of a rectangle are right angles.
Right angles measure up to 90 degrees.
JML is also a right angle which means 3x - 15 is equal to 90
3x - 15 = 90
3x = 105
x = 35
Why is everything due tomorrow xD. Also im sorry but I dont understand this either.
