Answer:
The answer is B (3 units right)
Step-by-step explanation:
You pick a point in the triangle which does not have an apostrophe. Then you see the correspondent point to it and see how much it has moved and in this case it is 3 to right therefore the answer is B.
Hint: If the apostrophe is after the letter, it shows translation therefore it is the moved shape
x = 375 and y = 6300. Option C.
Step-by-step explanation:
From the given data we need to find the value of x and y.
First, we will find out the ratio of area and the force.
= 
So,

or, x =
= 375
Again,

or, y = 420×15 = 6300
Hence,
x = 375 and y = 6300.
Let the number be x
2/3*x - 2 = 10
or, 2/3 * x =12
or x= 12*3/2
or, x = 18
Step-by-step explanation:

Answer:
Step-by-step explanation:
Since the whole right side of that triangle is equal to 28 and the lower portion is 21, then we know the upper portion is 7. Set up a proportion using those sides and the fact that the 2 triangles are similar:
and cross multiply to get
21x = 126 and
x = 6
