Answer:
Area: 24 Perimeter: 20
Step-by-step explanation:
Area (multiply side 1 by side 2):
4×6=24
Perimeter (add all of the sides together):
4+4=8
6+6=12
8+12=20
Answer: 86.34813
Step-by-step explanation:
l= (square root)r^2 + h^2 = (square root)20^2 + 84^2
Answer :
1) If x = 6
Substitute 6 for x in the expression.
a) 5x-9
5(6)-9
30-9
21
b) 2x-7
2(6) -7
12-7
5
c) 8x+5
8(6)+5
48+5
53
d) 4(x+3)
4(6+3)
4(9)
36
e) x²-(-4)
6²-(-4)
36+4
40
f) 3x²+1
3(6²)+1
3(36) +1
108+1
109
2) Solve
a) 54 = 3x
Divide both sides by 3.
54/3 = 3x/3
x = 18
b) x-9 = -3
Add 9 to both sides.
x-9+9 = -3+9
x = 6
c) x/7 = 140
Express the 140 over 1 and cross multiply.
x/7 = 140/1
x = 140×7
x = 980
d) x/8 = 72
Express the 72 over 1 and cross multiply.
x/8 =72/1
x = 72×8
x = 576
Answer:
That's a net- just use the same equation as lateral area then do surface area after that.
L=Ph
THEN....
A= L +2B
