Answer:
Step-by-step explanation:
1) 5xy - xy + 2x - 13x + 10xy - 8x =<u> 5xy - xy + 10xy</u> +<u>2x - 13x - 8x</u>
Combine like terms
= (5 -1 +10)xy + (2-13-8)x
= 14xy + (-19x)
= 14xy - 19x
2) -6c - (-6c) - (+6c) = -6c + 6c - 6c
= (- 6 + 6 - 6)c
= -6c
3) 0x - 22x - 4(2x) = 0x - 22x - 8x = -30x
The numeric value of the expression d² + 3a + 6 + a when a = 2 and d = 5 is of 39.
<h3>How to find the numeric value of an expression?</h3>
The numeric value of a function is found replacing each instance of a variable by the value of the input for which we want to find the numeric value.
For this problem, the expression is given by:
d² + 3a + 6 + a
We want to find the numeric value when a = 2 and d = 5, hence:
5² + 3(2) + 6 + 2 = 25 + 6 + 6 + 2 = 39.
