Answer:
The correct option is A.
Step-by-step explanation:
If the degree and variables of two terms are same, then they are called like terms.
In option A.
The given expression is
Here, 4ab and -3ab are like terms because both have same variables a and b with degree 1.
By combining like terms we get
In options B, C and D, there are no like terms, So only the expression we can simplify by combining like terms.
Therefore the correct option is A.
Answer:
answer is d if its wrong i am sorry
You have to isolate the variable just as if there was an equal sign
34280 + d + 1000 > 3680 (subtract 1000 from both sides)
34280 + d > 2680 (subtract 34280 from both sides)
d > -31600
We are asked to simplify the expression <span>sin (2 arcsin (5/13)). The technique is to simplify first the inner terms inside the parenthesis. arc sin of 5/13 under the radians mode in the calculator is equal to 0.3948. This is multiplied by 2 equal to 0.7896. sin of 0.7896 is equal to 120/169. </span>
so the first one is multiplying as the second one is division
Step-by-step explanation:
in division a higher number has to be divided but it multiplying this rule doesnt really matter and at first you probably weren't paying attention (not saying you were not) and you thought that they were both multiplication which is wrong but if you do the division and multiplication problem they end up with the same answer. Hope this helps :)
