The answer to your question is 4x^2 - 16
Hope this helped
The width is x
<span>The length is x+60 </span>
<span>so x(x+60) = 16000
</span>
<span>x^2 + 60x = 16000
</span>
<span> </span>
<span>x^2 + 60x + 900 = 900+16000
</span>
<span>(x+30)^2 = 16900
</span><span> </span>
<span>x+30 = 130
</span>
<span>x = 100
So your answer is 100. </span>
If f=4 then fx=8 but this question dosent make sense
Step-by-step explanation:
load=1000N
effort=250N
load arm=25cm
effort arm=?
Now,
E×E.D=L×L.D
250×E.D=1000×25
E.D=1000×25÷250
E.D=100cm
therefore,effort arm is 100cm.
