Answer:
1a = 8 cu. in.
1b = 48 cu. yd.
1c = 15 cu. ft.
2a. 36 cu. yd.
2b = 126 cu. ft.
2c = 90 cu. ft.
3a = 112 cu. in.
3b = 60 cu. yd.
3c = 189 cu. ft.

Answer:
Step-by-step explanation:
"length is 4 meters less than 2 times the width"
L = 2W+4
"perimeter is 40 meters"
2L+2W = 40
L+W = 20
(2W+4) + W = 20
3W + 4 = 20
W = 16/3 meters
Answer:
A AND D ARE CORRECT.
Step-by-step explanation:
IT IS A NUMBER LINE SO IT IS JUST BASIC ADDITION AND SUBTRACTION.
Answer:
7 cm
Step-by-step explanation:
Here is how I solve these problems:
Halve of 6 is 3
10 minus 3 is 7
you subtract 3 from 10 because when you collapse the side (10) onto that side other side (let us call it x), x is shorter that 10 by halve the height.
8^2 + 12 - 2(8)
64 + 12 - 16
76 - 16
60
so your answer would be 60
