Answer:
Step-by-step explanation:
the solid mineral material forming part of the surface of the earth and other similar planets, exposed on the surface or underlying the soil.
"the beds of rock are slightly tilted"
Step-by-step explanation:
1. d=6
proof
p(x)=x+3
p(-x)=-x+3
p(x)+p(-x)=x+3+(-x+3)=x+3-x+3=6
2. a=3xyz
we have identity
x³+y³+z³-3xyz=(x+y+z)(x²+y²+z²-xy-yz-zx)
if x+y+z=0
x³+y³+z³-3xyz=0
X3+y³+z³=3xyz
3. à=0
4. b=x³+X2+x+1
5. b=27
proof
(x+3)³
=X3+27+9x(x+3)
=x³+27+9x²+27x
=x³+9x²+27x+27
constant term=27
6. binomial
7. degree of polynomial
8.(-3x+y+z)²
=9x²y²+z²-6xy+2yz-6zx
9. 0.54*0.54-0.46*0.46
=(0.54)²-(0.46)²using a²-b²
=(0.54+0.46)(0.54-0.46)
=1.00*0.08
=0.08
10. 185*185-15*15
=185²-15²
=(185+15)(185-15)
=200*170
=34000
11. 105*108
(100+5)(100+8)using x+a*x+b
(100)²+(5+8)100+40
10000+1300+40
=11340
