Hey, Itd be easier if there was a picture but what subject is that
Answer:
81
Step-by-step explanation:
Range = maximum - minimum so here, we'd have:
52 = max - 29
Add 29 to both sides to solve.
One piece will be length x and the other piece will be 20 cm longer, so it will be x + 20 cm long.
Added together the length of these two boards will equal 86 cm. So you can write an equation:
x + (x + 20) = 86
Remove the parentheses and add the two x's together to get:
2x + 20 = 86
Subtract 20 from both sides:
2x = 66
Divide both sides by 2 and you have:
x = 33
The short piece is 33 cm and the other piece is 20 cm longer or 33 + 20 = 53 cm.
343 is a cube root of 7. Its surface area is 7
4,153+2,988
-12 +12
4,141+3,000
3,000+4,000=7,000
7,000+141=7,141
