Answer:
5
Step-by-step explanation:
A.3n+4+3n+4+4n
=3n+3n+4n+4+4
=10n+8
B.11n+4+n-12
=11n+n+4-12
=12n-8
C.6(6n-2)
=36n-12
D.4(3n-2)
=12n-8
E.4n+22-12+8n
=4n+8n+22-12
=12n+10
so,B and D are the expressions that are equivalent to 12n-8.
<span>length = 7x
</span><span>width = 2x
2(7x + 2x) = 72
7x + 2x = 72/2
9x = 36
x = 36/9
x = 4
</span>
width = 2x = 2 * 4 = 8 units<span>
</span>
Answer:
Well, with the info I have been given I would say; The L.A of a cylinder is SA+=2(pi)(r)(h).
Step-by-step explanation:
SA=Surface Area
LA=Lateral Area
Pi=3.14
R=Radius
H=Height
V=Volume
LA=2*pi*r*h <-- finds the Lateral Area of a cylinder
SA=LA+2*base or SA=2*pi*r*h+2*pi*r^2<-- finds the Surface Area of a cylinder
V=pi*r^2*h<---- Finds volume of the cylinder
Answer:44
Step-by-step explanation:
0.2x+(-0.9)+1.7==9.6
0.2x+0.8=9.6
Subtract 0.8 from both sides
0.2x+0.8-0.8=9.6-0.8
0.2x=8.8
Divide both sides by 0.2
0.2x ➗ 0.2=8.8 ➗ 0.2
x=44
