Answer:
-1 x 2 = -2
Step-by-step explanation:
f(-1)=-1 x 2+1 = -1
-1 x 2 = -2
-2 + 1 = -1
g(-1) = 3 x -1 +5 = 2
3 x -1 + -3
-3 + 5 = 2

Answer:
the second and third equations are true
Step-by-step explanation:
first equation
39-3*6=6*10/4+4
39-18=60/4+4
21=15+4
21=19
the equation is false
second equation
24/2^2=50-6^2-8
24/4=50-36-8
6=14-8
6=6
the equation is true
third equation
56/8+3^2=2*2^3
7+9=2*8
16=16
the equation is true
fourth equation
8^2-5^2=4^2-7
64-25=16-7
39=9
the equation is not true
X + 2 = 3/5(10) - 3
x + 2 = 6 - 3
x + 2 = 3
x = 3 - 2
x = 1 <=== ur number
V=hpir²
1/2 full
Vcylinderthisone=(1/2)hpir^2
given
h=250
r=100
so
V=(1/2)(250)pi(100)²
V=125pi10000
V=1250000pi
aprox pi=3.141592
V=3926990 cm^3
divide by 1000
3926.99 liters
about 3927 liters
