Answer:
31x³-60x²+7x-75
Step-by-step explanation:
(30x³-49x³+7x)+(50x³-60x²-75)
(-19x³+7x)+(50x³-60x²-75)
-19x³+50x³+7x-60x²-75
31x³-60x²+7x-75
We have that Using strictly the properties of addition to simplify
10v-6v+4s
From the question we are told
Use the properties of addition to simplify 10v – 4s – 6v +8s.
Generally the equation for the Statement is mathematically given as
10v – 4s – 6v +8s.
Therefore
WE collect like terms
10v – 4s – 6v +8s.
10v-6v-4s+8s
Therefore Using strictly the properties of addition to simplify
We have
10v-6v-4s+8s
10v-6v+4s

Perfect application for the Law of Cosines.
c^2 = a^2 + b^2 - 2ab cos C; here we want C, the angle opposite the 14 m side.
(14 m)^2 = (8 m)^2 + (12 m)^2 - 2(8 m)(12 m) cos C
196 = 64 + 144 - 192 cos C
-12 = -192 cos C, or cos C = 0.0625
Then C = arccos 0.0625 = 1.5083 radians
1.5083 radians 180 deg

1 3.14159 rad
= 86.417 degrees
= 86 degrees, when rounded off as specified.

Answer:
$15.25
Step-by-step explanation:
100% = 12.5
1% = 0.125
22% = 2.75
12.5+2.75=15.25
