In this question, you're solving for x.
Solve for x:
x + 4.2 = 7
You need to get x by itself, to do so, you would need to subtract 4.2 from both sides:
x = 2.8
Answer:
x = 2.8
To find distance between points <span>A(<span>xA</span>,<span>yA</span>)</span> and <span>B(<span>xB</span>,<span>yB</span>)</span>,
formula:
<span>d(A,B)=</span>√ [(xB−xA)^2+(yB−yA)^2]
so distance between the points: (–6, 7) and (–1, –5)<span>
</span>= √ [<span><span><span><span>(<span>−1−<span>(<span>−6</span>)</span></span>)^</span>2 </span>+ <span><span>(<span>−5−7</span>)^</span>2]
</span></span>= </span>√ (<span><span>25+144)
</span>= </span>√ 169
<span><span><span>= </span></span><span>13
answer
13</span></span>
