Answer:
300miles
Step-by-step explanation:
If you are driving 75 miles per hour, and you need to know how many miles you will have drive in 4 hours. Multiply 4 by 75 to get 300.
75mi 4 hr
____ x___ = 75mi x 4 = 300miles
1 hr y
Answer:
- By Double splitting method
=> 2x²-7x+5
=> 2x²-2x-5x+5
=>2x(x-1)-5(x-1)
<h2>=>(2x-5)(x-1)</h2>

Answer: B) Dilate by scale factor of 2
====================================================
Explanation:
Your teacher isn't saying this directly, but I'm assuming s/he wants you to find a similar figure that isn't congruent to the original. Informally, your teacher seems to want you to find a figure that is the same shape but not the same size as the original.
If so, then any dilation will shrink or enlarge the image depending on the scale factor. So the new image will not be the same as the old one. In this case, a dilation with scale factor 2 means the new figure is twice as large (each side is twice as long). But the old image is similar to the new image. The angles keep their values and therefore we get the same shape. This is why choice B is the answer. Again this is assuming what I mentioned in the first paragraph.
Choices A, C, and D are all known as rigid transformations and they preserve the same size of the figure. Applying any of those operations will lead to the same figure (just rotated, reflected or shifted somehow). In other words, applying operations A,C, or D will have us get two congruent triangles. If two triangles are congruent, then they are automatically similar, but not vice versa. This is why we can rule out A,C, and D.
Assuming you want to solve for x the result can vary. The result can be shown in multiple forms. Hope this helps!
