b) 1860, 1900, 2000
c) 200, 200, 0
d) 650, 600, 1000
e) 19900, 19900, 20000
Answer:
18 inches
Step-by-step explanation:
A=L·H
108 in²=L·6 in
L=
L=18 inches
2x-4(x+1)=-13
1) we solve this equation:
2x-4(x+1)=-12
2x-4x-4=-12
-2x=-12+4
-2x=-8
x=-8/-2
x=4
2) we evalute x²-1
x²-1=4²-1=16-1=15
Answer: 15
Answer:
178.3 mm²
Step-by-step explanation:
Surface area = Base area + 3 x side triangles area
Sₐ = 43.3 + 3 x (1/2 x (10 x 9)) = 43.3 + (3 x 45) = 178.3
16x = 45 - 29
16x = 16
x = 16/16
x = 1
