<span>Volume of a square = (s)(s)(s) and s=5a+4b
Therefore: (5a+4b)(5a+4b)(5a+4b)=
(25a^2+40ab+16b^2)(5a+4b)=
(125a^3+200a^2b+80ab^2+100a^2b+160ab^2+64b^3)= (125a^3+300a^2b+240ab^2+64b^3)
You just multiple the first time the second and then do so again with the combination of the first two times the second. A little cleaning up and you are left with an equation in terms of a and b.</span>
P=26=2*(l+L)
⇒ l+L=26:2=13 feet
l=3, L=10
A=l*L=30=10*3
⇒ l=3 feet
L=10 feet
Answer:
135ft^3
Step-by-step explanation:
Multiply all of the numbers to get your answer.
Nothing really, it is in my genetics that i have a middle toe longer than my big toe. My friend doesn't have the genetics and his middle toe is not as long as his big toe. It is all in genetics.
