Answer:
x = 2
Step-by-step explanation:
Since the triangles are similar then corresponding sides are in proportion, that is
= 
, substitute values
= 
( cross- multiply )
7x² = 28 ( divide both sides by 7 )
x² = 4 ( take square root of both sides )
x = 
= 2

Answer:
m=2
Step-by-step explanation:
Answer:
Step-by-step explanation:
- In order to combine these two equations, an idea you need to keep in mind is finding a way of setting these equations as equal to each other. I saw that each equation shared a common value,
. In this case, we need to isolate in the first equation so that both equations 
.
- With this, we now know that both
and 
are equal to , so we can set them equal to each other.
- Reply to this if anything I'm saying or doing is confusing in any way, or if you find a mistake. :) Solve for
.
- Hopefully this answer is correct AND makes sense in terms of how I achieved it. Again, reply to this with any questions or mistakes I made and I'll do my best to answer or fix them.
Answer:
- multiplying
- similar figures
- scale factor
- (x, y) (–3x, –3y) and (x, y) (0.23x, 0.23y)
- (x, y) --> (2x, 4y)
- Need diagram
- A. The line segment has become longer with endpoints D' (-12, -10) and E' (6 -8).
- Need image
- Reduction
- Enlargement
