Answer:
Step-by-step explanation:
(a + b + c)³ = a³ + b³ + c³ + 3a²b + 3a²c + 3ab² + 3cb² +3 ac² + 3bc² + 6abc
a = 5a ; b =y ; c = z
(5x + y + z)(5z + y + z )(5z + y +z) = (5x + y +z)³
= (5x)³ + y³ +z³ + 3(5x)²y + 3(5x)²z + 3(5x)*y² + 3*z*y² + 3*5x*z² + 3*y*z² + 6*5x*y*z
= 125x³ + y³ +z³ + 3*25x²y + 3*25x²*z + 15xy² + 3zy² + 15xz² + 3yz² + 35xyz
= 125x³ + y³ + z³ + 75x²y + 75x²z + 15xy² + 3zy² + 15xz² + 3yz² + 35xyz
Answer:
Step-by-step explanation:
a convex pentagon is basically just a pentagon which sides are either less than or equal to a straight angle
the answer is 60,000
For Connexus students:
1. 6,0000
2. 2,300
3. 9.68 x 10 to the 5th power
4. 8.6 x 10 to the 3rd power
5. the number of places to move the decimal point to the right
7x - (25x^2 + 12x) = 7x - 25x^2 - 12x = -25x^2 - 5x
