Answer:
3
Step-by-step explanation:
5(2x + 1) = 35
10x + 5 = 35
10x = 30
x = 3
If C is the MIDPOINT of BD, and BD equals 12, then what does CD equal?
AD = AC+CD, so you only need to find length of CD and add length of AC (which you already have) to it.
Hope this helps
If the triangle is a right triangle, then
(3x)² + x² = (10)² .
9x² + x² = 100
10x² = 100
x² = 10
x = √10 = approx. 3.1622...
If ' x ' is <em>anything less than √10</em> , then the short sides are too short
to make a right angle at the top, and the angle where they meet
is obtuse.
' x ' has to be greater than 2.5 ... otherwise the two short sides
can't stretch far enough to reach both ends of the long side (10) .
So, if 2.5 < x < √10 , then there is a triangle, and it's obtuse.

The 1st one isn't as clear in the picture, but it looks like the ends of each line overlap the each other.
Answer:108 houses
Step-by-step explanation:
Step 1: ratio of flats to bungalows is 10:5 and the bungalows are 30, therefore:
(10*30)/5 = 60 flats
Step 2: the ratio of houses to flats is 9:5 and the number of flats is 60, therefore
9*60/5 = 108 houses
