evaluate 5a + 3b and (5 + a)(3+B) for a=2 and b=4 how is the order of steps diffrent from the two expressions
Answers
second = 7x7 = 49
the order of the steps are different by the pluses and minuses
the first one had a multiply to 5 and b multiply to 3 and add them together
the second one had a plus 5 and b plus 3 and those two multiplied .

Answer: 3x-6xy-4y
Step-by-step explanation: So, it’s been a few years since I’ve been in high school, but if I remember correctly...it should break down as such...
A good method to breaking this down is to use parentheses to break up the equation.
Example: (2x)(-4xy)(+5x)(-2xy)(-4x)(-4y)
Keep in mind we are only using the parentheses as a breaker and not as multiplication as it can be seen.
So, start with the singular ‘x’ variants. (2x) (+5x) (-4x). 2x+5x is 7x. 7x-4x is 3x. Now, move onto ‘xy’ variant. (-4xy) and (-2xy). As these are both negative, they add together to make an even lower number...being -6xy. Onto the final step taking the singular ‘y’ variant. There’s only 1 ‘y’ variant so it just stays -4y.
In the end, you end up with 3x-6xy-4y. :) Hope this helps. If you have any more questions, let me know!

Answer: 60
Step-by-step explanation:
write down the 12 times table
12 , 24, 36, 48, 60, 72, 84, 96, 108, 120
20, 40, 60, 80, 100, 120, 140, 160, 180, 200
Now you can see that 60 is the multiple that comes up first in both of the times tables which means it is the lowest common factor.

The domain of f o g is all x-values less than or equal to 1/4. So, the correct answer is B. 1.
What is Function ?
Function can be defined in which it relates an input to output.
To determine the domain of f o g, we need to first find the composition of f and g.
f o g(x) = f(g(x))
= √4(1/x - 4) = √(4/x - 16)
The domain of f o g is the set of all x-values for which the expression √(4/x - 16) is defined.
For the expression under the square root to be defined, we need:
4/x - 16 ≥ 0
4/x ≥ 16
x ≤ 4/16
x ≤ 1/4
Therefore, the domain of f o g is all x-values less than or equal to 1/4. So, the correct answer is B. 1.

Hello!
Answer:
Step-by-step explanation:
→ We want an expression wich is equivalent with (st)(6).
→ Let's develop this expression:
Conclusion:
So an equivalent expression of (st)(6) is s((t)(6)).
Final answer:
The term (st)(6) in mathematics signifies that 's' and 't' are multiplied together, and the result is then multiplied by '6'. Using the associative property of multiplication, the equivalent expression is s(t(6)).
Explanation:
In mathematics, the expression (st)(6) signifies multiplication. The presence of parentheses indicates that the variables 's' and 't' should be multiplied together first, and then the product should be multiplied by '6'. This principle is known as the associative property of multiplication, which states that the way in which factors are grouped in a multiplication problem does not change the product. Therefore, the equivalent expression to (st)(6) is s(t(6)), which means 's' multiplied by the product of 't' and '6'.
