7 ∫ cos(πx) dx
7 [ sin(πx)/π ]
7/π (sin(π/2) - sin(0))
7/π (1 - 0)
7/π ~ 7/3
They are equivalent. combine like terms on the first one and 9x-4x+25 can be simplified to 5x+25.
Answer:
Step-by-step explanation:
(8-2)*180=1080 degrees
114+66+94+259+94+67+254+97+x=1080
1045+x=1080
1080-1045=x
x=35
We have that
t²<span> – 81
</span>
we know that
A difference of two perfect squares, <span> (A</span>²<span> - B</span>²)<span> </span><span>can be factored into </span><span> (A+B) • (A-B)
</span> let
A²-------> t²
B²-------> 9²
then
(t² – 9²)------->(t+9)*(t-9)
the answer is
(t+9)*(t-9)
There are 12 inches in every foot 5 x 12 is 60 half a foot would be 12÷2=6 so 60+ 6=66 inches
