Reduce −2 + b2 by 7 + b2.

2 answers:

8 0

To simplify (-2+b^2)-(7+b^2), first distribute the -1 to both terms in the second parenthesis.
-2+b^2-7-b^2
Combine like terms.
-9 (1-1=0, so the b^2 is canceled out.)
(-2+b^2)-(7+b^2)=-9

What is the distance between the longest dog in the shortest dog Short 7 over 8 longest 3 over 8 what is the difference

Step2247 [10]

Answer:

The distance between the longest dog and the shortest dog is 4 over 8 ( $\frac{4}{8}$ ) OR 1 over 2 ( $\frac{1}{2}$ )

Step-by-step explanation:

From the question,

Short is 7 over 8, that is,

Short = $\frac{7}{8}$

and longest is 3 over 8, that is

Longest = $\frac{3}{8}$

The distance between the longest dog and the shortest dog can be determined by finding the difference between the fractions. That is,

$\frac{7}{8} - \frac{3}{8} = \frac{7 - 3}{8}$

$= \frac{4}{8}$

$= \frac{1}{2}$

Hence, the distance between the longest dog and the shortest dog is 4 over 8 ( $\frac{4}{8}$ ) OR 1 over 2 ( $\frac{1}{2}$ ).
