D=√(1.5)(1.4)
d= √6
d= 2.44948.....
Rounded to the nearest tenth would be c. 2.4 mi
Answer:
Try and pick out the numbers and what the problem is telling you about those numbers. Ignore names all the details that are thrown in to confuse you.
Step-by-step explanation:
Answer:
56n - 7m
Explanations:
Note that according to the distributive property:
a(b + c) = ab + ac
a(b - c) = ab - ac
Therefore, follow the rule above to rewrite 7(8n - m) using the distributive property.
7(8n - m) = 7(8n) - 7m
7(8n - m) = 56n - 7m
The greatest common factor in this expression is 3x^4. Let's take it out:
3x^4(u^4 - 1)
u^4 - 1 is a difference of two squares and can be factored further:
3x^4(u^2 + 1)(u^2 - 1)
u^2 - 1 is also a difference of two squares:
3x^4(u^2 + 1)(u + 1)(u - 1)
