Step-by-step explanation:
hope this helps. I had this question and got it right!
Answer:
The value of n is 1
Step-by-step explanation:
Given the expression 
In other to solve for n we have to perform a series of step wise operations as follows
collecting like terms we have


The negative signs will council out on both sides we have

Dividing both sides by 2 we have
n= 

we have
(a+b)(3a-b)(2a+7b)
step 1
Solve
apply distributive property
(a+b)(3a-b)=3a^2-ab-3ab-b^2=3a^2-4ab-b^2
step 2
Multiply (3a^2-4ab-b^2) by (2a+7b)
6a^3+21a^2b-8a^2b-28ab^2-2ab^2-7b^3=6a^3+13a^2b-30ab^2-7b^3
answer is
<h2>6a^3+13a^2b-30ab^2-7b^3</h2>
Answer:
245+45x=170+60x
therefore in 5 days, they will charge the same amount
The
correct answer is in file attached
<span>we have<span>
</span>
triangle RST<span>
</span><span>m∠R = 60, m∠S = 80 and m∠T=180-(80+60)=40</span></span>
<span>RS=4<span>
</span>
triangle EFD<span>
</span><span>m∠F = 60, m∠D = 40 and m∠E=180-(60+40)=80</span></span>
EF=4
Therefore
<span>The triangles
RST<span> and </span>
EFD are
congruents because they have two angles and the side common to them,
respectively, equal.
This is the theorem of ASA (angle-side-angle).</span>
Explication
Side common--------> RS=EF
<span>Angles RS------------- > m∠<span>R =
60 m</span>∠S =
80 </span>
<span>Angles EF------------- > m∠<span>E =
80 m</span>∠F = 60 </span>
<span>The segment which is congruent
to RT is FD, because angles of RT are 60 and 40, and angles of FD also are 60
and 40.</span>
