The answer is B. "Four times further."
C and D are incorrect because a dilation makes an image larger. Therefore the answer would be B.
I hope this was helpful.
Ok here is how you do this:
you need to replace y with 20 and then solve to find x, i.e. solve this equation
20=2/5x
1. Simplify 2/5x to 2x/5
20=2x/5
2. Multiply both sides by 5
20 * 5=2x
3. Simplify 20 * 5 to 100
100=2x
4. Divide both sides by 2
100/2=x
5. Simplify 100/2 to 50
50=x
6. Switch sides
x=50
so your answer is B. 50
I hope this helped!
Answer:
A, C
Step-by-step explanation:
I had answered this earlier, so you better look back at that question.
To reiterate, use the Pythagorean Theorem a^2+b^2=c^2.
If a^2+b^2=c^2, it is a right triangle.
*remember that squaring a square root results in just the number inside the square root.
