Jayden correctly simplifies the expression 9x(2+7x) using the following steps Step 1. 9(7x+2) Step 2. 9(7x) +9(2) Step 3. (9x7)x+18. What are the properties for each one?
How to solve:
Let's follow his process step-by-step to analyze what property is being used. The breakdown is as follows:
Process:Jayden's work
Set up equation 9(2 + 7x)
Step 1 9(7x + 2)
Step 2 9(7x) + 9(2)
Step 3 (9*7)x + 18
Breakdown
Set up equation 9(2 + 7x)
Step 1: Commutative Property of Addition
This property states that when adding, the order of the numbers being added does not matter, and are therefore interchangeable.
Original equation: 9(2 + 7x)
Equation's formula: a(b + c)
Changed equation: 9(7x + 2)
Equation's formula: a(c + b)
By swapping the b and c values in the parentheses, Jayden is demonstrating the Commutative Property. Both will still produce the same sum.
Step 2: Distributive Property of Multiplication
This property states that the sum of two addends that are multiplied by the same number is equal to the product of that number multiplying the sum of both addends.
Original equation: 9(7x + 2)
Equation's formula: a(c + b)
Changed equation: 9(7x) + 9(2)
Equation's formula: a(c) + a(b)
By splitting the parentheses and multiplying each term separately, Jayden is demonstrating the Distributive Property. Both will produce the same product.
Step 3: Associative Property of Multiplication
This property states that the product of three terms, where one is outside of the parentheses multiplying the other two, is not affected by changing which term is on the outside of the parentheses.
Original equation: 9(7 * x) +18
Equation's formula: a(c*x) + (ab)
Changed equation: x(7*9) + 18
Equation's forumula: x(c*a) +18
By swapping the 9 and x variables, Jayden is demonstrating the Associative Property. Both will produce the same product.
Simplified:
Step 1 - Commutative Property
Step 2 - Distributive Property
Step 3 - Associative Property
The net of a square pyramid and its dimensions are shown in the diagram. What is the total surface area in square feet?
1,120 ft^2
5,760 ft^2
1040 ft^2
976 ft^2
Answer:
c
Step-by-step explanation:
The surface area of the square pyramid is 1040 ft² in the given figure.
What is the total surface area of the pyramid?The total surface area of the given pyramid can be expressed as:
Surface area of a square pyramid = A + (1/2) p × s
where A is the base area, p is the perimeter of the base, and s is the slant height
As per the question, we have
length (l) = 20 ft
base perimeter (p) = 4l = 4 × 20 = 80 ft
base area (A) = l² = 20² = 400 ft²
slant height (s) = 16 ft
Substitute the values in the formula for surface area:
Surface area = 400 + 1/2 × 80 × 16
Surface area = 400 + 1280/2
Surface area = 400 + 640
Surface area = 1040 ft²
Thus, the surface area of the square pyramid is 1040 ft².

Answer:
16.2 = [tex]\frac{81}{5}[/tex] and 121 = [tex]\frac{121}{1}[/tex]

Question A: Mai pumped 10 gallons out of her pool. This meaning she is taking out water or a negative sign. She does this in a period of 5 minutes.
The expression should be:
-10 / 5 = -2 | 10 / 5 = 2
so basically either -2 or 2
Question B: Tony added 3 fish to his pond each day for 21 days.
This meaning you have to multiply 3 x 21 or add 3 twenty-one times.
3 x 21 = 63 | 3 + 3 + 3 + 3 + 3 + 3 + 3...
Either method coming to a total of 63.

what value of x makes the equation true 3/4x + 9 = 3
A. x = -8
B. x= -1/2
C. x = 1
D. x = 16
Answer:
[tex]\boxed{\sf{A. \quad X=-8}}[/tex]Step-by-step explanation:
To find the value of x, isolate it on one side of the equation.
3/4x+9=3
First, subtract by 9 from both sides.
3/4x+9-9=3-9
Solve.
3-9=-6
Rewrite the problem down.
3/4x=-6
Multiply by 4 from both sides.
4*3/4x=4(-6)
Solve.
3x=-24
Then, you divide by 3 from both sides.
3x/3=-24/3
Solve.
Divide these numbers goes from left to right.
-24/3=-8
x=-8
Therefore, the correct answer is A. x=-8.Variables and negative signs should appear in the answer.
I hope this helps you! Let me know if my answer is wrong or not.
Answer:
x = -8
Step-by-step explanation:
Subtract 9 both sides:
⇒ 3/4x + 9 = 3
⇒ 3/4x + 9 - 9 = 3 - 9
Simplify the L.H.S and the R.H.S:
⇒ 3/4x = -6
Use cross multiplication:
⇒ 3x/4 = -6
⇒ 3x = -6 × 4
Simplify the R.H.S:
⇒ 3x = -6 × 4
⇒ 3x = -24
Divide 3 both sides:
⇒ 3x/3 = -24/3
⇒ x = -8

Choose 1 answer:
A) Vertical angles
B) Complementary angles
C) Supplementary angles
D) None of the above
Answer:
D) None of the above
Step-by-step explanation:
Let's use process of elimination!
A) Vertical angles are opposite angles formed by two intersecting lines. These two are adjacent, therefore rendering this statement false.
B) Complementary angles are two adjacent angles that add up to 90 degrees. There is no proof that m∠a+∠b=90°, therefore this statement is false.
C) Supplementary angles are two adjacent angles that add up to 180 degrees. Assuming A∈ED, this statement is false as well.
D) None of the answers above are correct.
