Below is the solution:

A(final)=16cm^2 ds/dT=6 da/dT=?

<span>A=(s)^2 A=16cm^2 , s=sqrt(A) , s=sqrt(16) , s=4cm </span>

<span>da/dT=2(s)(6cm/sec) , da/dT=12cm/sec(s) , da/dT=12cm/sec (4cm)
</span>
<span>Answer should be da/dT=48cm^2/sec
</span>

M=8+n<br> PLZ HELP ASAP, WILL MARK BRAINLIEST!!!

irina [24]

$\\ \qquad\quad\sf\longmapsto m=8+n$

Take n to left

$\\ \qquad\quad\sf\longmapsto m-n=8$

Hence

if m=1

$\\ \qquad\quad\sf\longmapsto n=m-8=1-8=-7$

if n=1

$\\ \qquad\quad\sf\longmapsto m=8+1$

$\\ \qquad\quad\sf\longmapsto m=9$
