Step-by-step explanation:
6x^2 + 12x + 3x + 6
6x^2 + 15x + 6
Answer:
6x² + 15x + 6
Step-by-step explanation:
Use FOIL:
Multiply the first terms:
(2x)(3x) = 6x²
Multiply 2x and 6:
(2x)(6) = 12x
Multiply 1 and 3x:
(1)(3x) = 3x
Multiply 1 and 6:
(1)(6) = 6
Then, add these all together:
6x² + 12x + 3x + 6
Add like terms:
6x² + 15x + 6 is the simplified expression

what is the parallel slope intercept form pls help?
If the line is parallel to the one given, their slopes are the same, so we need to find the y-intercept, then we can determine the slope-intercept form parallel to the given line.
[tex]-1 = 4(4) + b\\\\-1 = 16 + b\\\\-17 = b[/tex]
Now that we have the y-intercept, we can create the equation.
[tex]y = 4x - 17[/tex]
We can prove this by graphing both lines, like so.

4) There are 3 blue counters, 5 red counters and 7 green counters in a bag.
A counter is taken from the bag at random.
a. What is the probability that a green counter will be chosen?
b. What is the probability that a blue or red counter will be chosen?
Answer:
for the green I think 7 : 15
Answer:
a) 7/15
b) 8/15
Step-by-step explanation:
a- 3 + 5 + 7 = 15 counters total, 7 green counters = 7/15
b- 3 blue + 5 red = 8 = 8/15 counters

Step-by-step explanation:
A tree is currently 10 feet tall and grows 2 feet per year. Show your work for full credit.
a. Model this scenario with an arithmetic sequence in explicit form. (2)
b. Rewrite the explicit form of the sequence using function notation. (2)
c. How tall will the tree be in 15 years? (1)
Answer:
(a) An = 2n +8
(b) F(n) = 10 + (n-1)2
(c) 38ft tall
Step-by-step explanation:
The tree is currently 10 feet long and grown 2 feet per year.
The arithmetic sequence is
10 , 12, 14 , 16 , 18 ..............
a( initial value) = 10 , d (common difference) = 2
Explicit forms
(a) An = a +(n-1)d
An = 10 + (n-1)2
= 10 + 2n -2
An = 2n +8
(b) F(n) = 10 + (n-1)2
(c) Height of the tree after 15 years
F(15) = 10 + (15-1)2
= 10 + 28
= 38ft
So the tree will be 38ft tall after 15 years.
Given that n^2/3 = 8 and n> 0
work out the value of n.
Give your answer in the form a square root b where a and b are integers.
Answer:
16[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Using the rule of exponents/ radicals
[tex]a^{\frac{m}{n} }[/tex] = [tex]\sqrt[n]{a^{m} }[/tex] , then
[tex]n^{\frac{2}{3} }[/tex] = [tex]\sqrt[3]{n^2}[/tex] , then
[tex]\sqrt[3]{n^2}[/tex] = 8 ( cube both sides )
n² = 8³ ( take the square root of both sides )
n = [tex]\sqrt{8^3}[/tex]
= [tex]\sqrt{512}[/tex]
= [tex]\sqrt{256(2)}[/tex]
= [tex]\sqrt{256}[/tex] × [tex]\sqrt{2}[/tex]
= 16[tex]\sqrt{2}[/tex]

If 16x-2=30 what is the value of 8x-4?
Answer:
12
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define 1st equation
16x - 2 = 30
Step 2: Solve for x
Add 2 on both sides: 16x = 32Divide 16 on both sides: x = 2Step 3: Solve equation
Define: 8x - 4Substitute: 8(2) - 4Multiply: 16 - 4Subtract: 12And we have our final answer!

Henry runs up 10 flights of stairs.
Then, he runs down 10 flights of stairs.
Does this situation represent additive
Inverses? Explain.
Answer:
Yes, it does
Step-by-step explanation:
When we add a number to its additive inverse, the resulting value is zero
The first case is running up 10 flights which we consider positive
then he runs down 10 flights of stairs; this we can consider as - 10
So adding this together, we have -10 + 10 to give zero
What this mean is that we have added a number to its additive inverse

Laqueta has three times as many quarters as Pablo if they each spend $.50 Laqueta will have five times as many quarters as Pablo how many quarters do Laqueta and Pablo have now?
Answer:
Number of quarters with Pablo = 4
Number of quarters with Laqueta = 12
Step-by-step explanation:
Given that:
Laqueta has three times as many quarters as Pablo.
They both spend $0.50.
After that Laqueta will have 5 times as many quarters as Pablo.
To find:
Number of quarters with Laqueta and Pablo now?
Solution:
Let number of quarters with Laqueta = [tex]x[/tex]
Let number of quarters with Pablo = [tex]y[/tex]
As per given statement:
[tex]x=3y ..... (1)[/tex]
In $0.50, there are 2 quarters:
After spending $0.50, number of quarters left with both of them:
Number of quarters left with Laqueta = [tex]x[/tex] - 2 = [tex]3y-2[/tex]
Money left with Pablo = [tex]y[/tex] - 2
As per given statement:
[tex]3y-2 = 5(y-2)\\\Rightarrow 3y-2 = 5y-10\\\Rightarrow 2y = 8\\\Rightarrow y = 4[/tex]
Therefore, the answer is:
Number of quarters with Pablo = 4
Number of quarters with Laqueta = [tex]3 \times 4[/tex] = 12

Enter the number that belongs in D= ?
Answer:
∠ D = 80°
Step-by-step explanation:
Δ BCA and Δ DCE are congruent ( SAS postulate )
Thus corresponding angles are congruent, thus
∠ D = ∠ B
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles in Δ ABC from 180° to find ∠ B
∠ B = 180° - (30 + 70)° = 180° - 100° = 80°, then
∠ D = 80°
