Question

Даю 20 баллов. 1 Приведите подобные члены -0.4a-0.21a+0.35a 2 Найдите одночлен равный разности подобных одночленов 3.1ax и +4.2ах Помогите плиз )

Answer 1

- 0,4 а - 0,21а + 0,35а = - 0,26а
4,2 ах - 3,1ах = 1,1ах

Answer 2

-0.4a-0.21a+0.35a = a*(-0.4-0.21+0.35) = a*(-0.61+0.35) = -0.26a
3.1ax - 4.2ах = ах*(3.1 - 4.2) = -1.1ах

Answer 3

Solving Algebraic Expressions

1. Combining Like Terms: To combine like terms, we add or subtract the coefficients of the same variable. In this case, we have the expression -0.4a - 0.21a + 0.35a.

The combined expression is: \[-0.4a - 0.21a + 0.35a = -0.26a\] [[1]]

2. Finding a Monomial Equal to the Difference of Like Terms: We are given the monomials 3.1ax and 4.2ax. To find a monomial equal to the difference of these monomials, we subtract the smaller coefficient from the larger coefficient and keep the variable and its exponent the same.

The monomial equal to the difference of 3.1ax and 4.2ax is: \[4.2ax - 3.1ax = 1.1ax\] [[2]]
