If you mean 7 times 4y then it is 28y If you mean 7x times 4y then it is 28xy
The expression -28x+35 is equivalent to 7y(-4x+5)
2a to the second power. If you combine the like terms, (a to the second power + a to the second power), it would be the same as 2a to the second power.
8x to the second power is 64x2
what is 7x to the third power + 6x to the second - 2
gcd of 5ab,28xy
84x2y2
4x^(2) + 28xy + 49y^(2) -> (2x)^(2) + 28xy + (7y)^2 Split into brackets ( 2x + 7y)(2x + 7y) If you applyuFOIL you will find toy come to '28xy'. The clue to this problem is to note that '4' ^ '49' are both squared numbers.
2x2 + 28xy + 98y2 = 2(x + 7)2.
(4x + 7y)(16x2 - 28xy + 49y2)
98
The LCM of 28 and 42 is 84. Since y2 and x2 are multiples of y and x respectively, they are automatically the LCM. That makes the answer 84x2y2
If you mean 7 times 4y then it is 28y If you mean 7x times 4y then it is 28xy
The expression -28x+35 is equivalent to 7y(-4x+5)
2a to the second power. If you combine the like terms, (a to the second power + a to the second power), it would be the same as 2a to the second power.
12 to the second power is 144...2 to the second power is 4, any # to the second power is the # times itself.
