Each term differs by -68 and the first term is -68, we have:

As an expession it's just -68n.
RhTh + RsTs = 180 (Rh = 70, Rs=20 , Th = Ts)
70Th + 20Th = 180
90 Th = 180
Th = 2
since Th = Ts,
thus, Ts = 2
The area A of a triangle with base b and height h is given by A=1/2bh,find the area when b=28m(meters) and h=38m. The area is m
56 + 32 = (8 x 7) + (8 x 4) = 8(7 + 4) (Answer C)
Gh - k
<span>g= -6, h= 15, and k= -27
</span>
-6*15 - - 27
-90 + 27
-63 is the answer to the expression.
