<u>Answer:</u>
<u>Step-by-step explanation:</u>
- Surface area: 2(4 x 0.5) + 2(4 x 1.5) + 2(0.5 x 1.5)
- => 2(2) + 2(6) + 2(0.75)
- => 4 + 12 + 1.5
- => 17.5 ft.²
<u>Conclusion: </u>
Therefore, the surface area is 17.5 ft.².

Answer:
Step-by-step explanation:
6: 6, 12, 18, 24, 30, 36, 42, 48, 54
14: 14, 28, 42, 56
the LCM (least common multiple) is 42.
Answer:
41 and 77
Step-by-step explanation:
x: his age the first time he went to space
y: his age the second time he went to space
the second time he went to space he was 5 years younger than twice the age when he went his first time, then:
y = 2x - 5
the sum of both ages is 118, then:
x + y = 118
If you replace y = 2x - 5 in x + y =118:
x + 2x - 5 = 118
3x = 123
x = 41
replacing x:
41 + y = 118
y = 118 - 41
y = 77
so when he was 77, he was 5 years younger than twice 41 ( 41*2 = 82 => 82 - 5 =77)
