Answer:
0.35
Step-by-step explanation:
0.25 × 1.4 =
0.25×100=25
1.4 × 10 = 14
25×10=250
25×4=100
250+100=350
25×14=350
350÷1000(0.25》25, 1.4》14)
0.35
Answer:
13.6 inches
Step-by-step explanation:
We can use Pythagorean theorem: 
Let c be the diagonal length, a for length, and b for width.
Substitute the values.

c=13.6 inches
Make bottom number same
ok, so remember
(a-b)(a+b)=a²+b²
so
to get from (y-x) to (y²-x²), multiply 2nd fraction by (y+x)
so multiply 2nd fraction by (y+x)/(y+x)

=

=
