I think the simplify expression is 2^2 x 7 = 28. Sorry if it is wrong
2 1/2 and -2 1/2 beacause negative absolute value is the same number without negative sign
The perfect cubes less than 1000 are:
<span>1^3 = 1 </span>
<span>2^3 = 8 </span>
<span>3^3 = 27 </span>
<span>4^3 = 64 </span>
<span>5^3 = 125 </span>
<span>6^3 = 216 </span>
<span>7^3 = 343 </span>
<span>8^3 = 512 </span>
<span>9^3 = 729
</span>
so
<span>2^3 = 8 could only be 1 + 1, but this is 2, not 8. </span>
<span>3^3 = 27 could be 1 + 1, 1 + 8 or 8 + 8, but all of these are too small </span>
4^3 = 64 could be 1 + 1, 1 + 8, 1 + 27, 8 + 8, 8 + 27, 27 + 27.
<span> general proof that a^3 + b^3 = c^3 holds for no positive integers
</span>hope it helps
Answer:
l=24in
Step-by-step explanation:
P=2(l+w)
l=P
2﹣w=68
2﹣10=24in
