__________________
We have a dilemma here, there is a variable and constant numbers in this equation. No fear, this is when like terms comes into play, where you can only combine two numbers that have the same ending, whether it be variables, exponents, e.t.c.
Distribute :
4 + 16 - 12(1 + 2x)
4 + 16 - (12(1) + 12(2x))
4 + 16 - 12 + 24x
Use PEMDAS (Add left to right) :
4 + 16 - 12 + 24x
20 - 12 + 24x
8 + 24x
24x + 8
8-24x is your answer
Step-by-step explanation:

The nth term of a sequence is 3n²-1
The nth term of a different sequence is 30–n²
Find the only number that is in both of these sequences.
Answer: The number is 26.
Step-by-step explanation:
We know that:
The nth term of a sequence is 3n²-1
The nth term of a different sequence is 30–n²
We want to find a number that belongs to both sequences (it is not necessarily for the same value of n) then we can use n in one term (first one), and m in the other (second one), such that n and m must be integer numbers.
we get:
3n²- 1 = 30–m²
Notice that as n increases, the terms of the first sequence also increase.
And as n increases, the terms of the second sequence decrease.
One way to solve this, is to give different values to m (m = 1, m = 2, etc) and see if we can find an integer value for n.
if m = 1, then:
3n²- 1 = 30–1²
3n²- 1 = 29
3n² = 30
n² = 30/3 = 10
n² = 10
There is no integer n such that n² = 10
now let's try with m = 2, then:
3n²- 1 = 30–2² = 30 - 4
3n²- 1 = 26
3n² = 26 + 1 = 27
n² = 27/3 = 9
n² = 9
n = √9 = 3
So here we have m = 2, and n = 3, both integers as we wanted, so we just found the term that belongs to both sequences.
the number is:
3*(3)² - 1 = 26
30 - 2² = 26
The number that belongs to both sequences is 26.

Antonio ran 129 laps at the park. Alan ran 20% more than that. how many laps did Alan run
Answer:
154.8
Step-by-step explanation:
20% is equal to 20/100= 0.20. So, 0.20 multiplied by 129 will give you 20% of 129 which is 25.8. If Alan ran 20% more then you add 25.8 to 129 which gives you an answer of 154.8.
Equation: 20/100= 0.2
0.2* 129= 25.8
25.8+129= 154.8
Alan ran 154.8 laps.

Evaluate the expression when y= 7 and x = 9.
x + 4y
Answer:
[1] 9x - 4y = 7
[2] x - 4y = -17
[2] x = 4y - 17
// Plug this in for variable x in equation [1]
[1] 9•(4y-17) - 4y = 7
[1] 32y = 160
// Solve equation [1] for the variable y
[1] 32y = 160
[1] y = 5
// By now we know this much :
x = 4y-17
y = 5
// Use the y value to solve for x
x = 4(5)-17 = 3
Step-by-step explanation:
Answer:
9+4(7)
Step-by-step explanation:
Start by replaceing y with 7
