Name the like terms 5a, 3, 4d , 2a, 2a, 5c

Vsevolod [243]

Answer:

"Like terms" are terms whose variables (and their exponents such as the 2 in x2) are the same. In other words, terms that are "like" each other. Note: the coefficients (the numbers you multiply by, such as "5" in 5x) can be different.

If x+y+z=9, xy+yz+zx =26; find x²+y²+z²

vichka [17]

First, we must expand and simplify :
$x + y+z = 9$

$(x + y+z)^{2} = (9)^{2}$

$x^{2} + y^{2}+z^{2} + 2(xy + yz+zx) = 81$

And Than, Enter the value :
$x^{2} + y^{2}+z^{2} + 2(26) = 81$

$x^{2} + y^{2}+z^{2} + 52 = 81$

$x^{2} + y^{2}+z^{2} = 81- 52$

$\boxed{x^{2} + y^{2}+z^{2} = 29}$
