Answer:
[tex]3 {x}^{2} + 2x[/tex]
Step-by-step explanation:
Expanding brackets means multiplying every term inside the bracket by the term on the outside and then collecting like terms with the aim of removing the set of brackets
[tex]x(3x + 2) = 3 {x}^{2} + 2x[/tex]
3x² + 2x
Step-by-step explanation:Given equation, x(3x + 2)
= x(3x + 2)
Distributive property
= {(x * 3x) + (x * 2)}
= {(1 * x * 3 * x) + (1 * x * 1 * 2)}
Rearranging like terms
= {(1 * 3 * x * x) + (1 * 1 * 2 * x)
= [{(1 * 3) * (x * x)} + {(1 * 1 * 2) * x)}]
= {(3 * x²) + (2 * x)}
= (3x²) + (2x)
= 3x² + 2x

The diameter of a hat is 6.8 inches. What is the distance around the hat using π = 3.14? Round to the hundredths place.
2.17 inches
10.68 inches
21.35 inches
36.29 inches
Answer:
21.35 inches
Step-by-step explanation:
Hello!
The distance around the hat is also called the circumference (the perimeter of a circle). To find this, we use the formula: [tex]C = 2\pi r[/tex], where r is the radius.
If we don't have a given radius when solving for circumference, we can use the diameter, and then the formula would change to [tex]C = \pi D[/tex] (2r is the same as D), where D is the diameter.
Given that the diameter is 6.8, and the desired value of Pi is 3.14, we can solve for the circumference.
Solve for the Circumference:C = πDC = (3.14)(6.8)C = 21.352 ≈ 21.35The circumference is approximately 21.35 inches.

2x(3x+2y)
Answer:
[tex]6 {x}^{2} + 4xy[/tex]
Step-by-step explanation:
Expanding brackets means multiplying every term inside the bracket by the term on the outside and then collecting like terms with the aim of removing the set of brackets
[tex]2x(3x + 2y) = 6 {x}^{2} + 4xy[/tex]
.
Step by step:
[tex]2x \times 3x = 6 {x}^{2} [/tex]
[tex]2x \times 2y = 4xy[/tex]
6x² + 4xy
Step-by-step explanation:Given equation, 2x(3x+2y)
= 2x(3x+2y)
Distributive Property
= (2x * 3x) + (2x * 2y)
= (2 * x * 3 * x) + (2 * x * 2 * y)
Rearranging like terms
= {(2 * 3 * x * x) + (2 * 2 * x * y)}
= [{(2 * 3) * (x * x)} + {(2 * 2) * (x * y)}]
= {(6 * x²) + (4 * xy)}
= (6x²) + (4xy)
= 6x² + 4xy

This quarter circle has a radius of 6 cm. What is approximate area of this figure? Use 3.14 for pi. Round to the nearest hundredth.
Answer:
probably my last question for the day but the answer is 28.26 square centimeters.
Step-by-step explanation:
The formula to find the area of a quarter circle is:
A = (1/4)πr^2
where A is the area and r is the radius.
Substituting the given values:
A = (1/4) × 3.14 × 6^2
A = 28.26
Rounding to the nearest hundredth, the approximate area of the figure is 28.26 square centimeters.

Based on the surface area and cost of the boxes, the company saves $11.50 by choosing to make 50 Box 2 instead of 50 Box 1.
What is the cost of the boxes?To solve this problem, we need to calculate the surface area of each box to determine how much material is needed to make 50 of each box.
The surface area of Box 1 is:
SA1 = 2lw + 2lh + 2wh
SA1 = 2(206) + 2(204) + 2(6*4)
SA1 = 240 + 160 + 48
SA1 = 448 square inches
To convert to square feet, we divide by 144 (since there are 144 square inches in a square foot):
SA1 = 448/144
SA1 = 3.11 square feet
The cost of material for one Box 1 is:
C1 = 1.25 * SA1
C1 = 1.25 * 3.11
C1 = $3.89
The surface area of Box 2 is:
SA2 = 2lw + 2lh + 2wh
SA2 = 2(154) + 2(158) + 2(4*8)
SA2 = 120 + 240 + 64
SA2 = 424 square inches
Converting to square feet:
SA2 = 424/144
SA2 = 2.94 square feet
The cost of material for one Box 2 is:
C2 = 1.25 * SA2
C2 = 1.25 * 2.94
C2 = $3.67
To find the cost savings of making 50 Box 2 instead of 50 Box 1, we calculate the difference in cost:
Savings = (50 * C1) - (50 * C2)
Savings = (50 * 3.89) - (50 * 3.67)
Savings = $11.50

Polygon ABCD with vertices at A(−4, 6), B(−2, 2), C(4, −2), and D(4, 4) is dilated using a scale factor of three eighths to create polygon A′B′C′D′. If the dilation is centered at the origin, determine the vertices of polygon A′B′C′D′.
A′(−1.5, 2.25), B′(−0.75, 0.75), C′(1.5, −0.75), D′(1.5, 1.5)
A′(−12, 18), B′(−6, 6), C′(12, −6), D′(12, 12)

A′(1.27, −3), B′(3.2, −3.2), C′(−0.75, 3), D′(3, 3)
Answer:
First choice: A′(−1.5, 2.25), B′(−0.75, 0.75), C′(1.5, −0.75), D′(1.5, 1.5)
Step-by-step explanation:
A(-4, 6) x 3/8 → A'(-12/8, 18/8) = A'(-1.5, 2.25)
B(-2, 2) x 3/8 → B'(-6/8, 6/8) = B'(-0.75, 0.75)
C(4, -2) x 3/8 → C'(12/8, -6/8) = C'(1.5, -0.75)
D(4, 4) x 3/8 → D'(12/8, 12/8) = D(1.5, 1.5)

Answer:
1) x = -11
2) x= -9
3) x = -1
4) x = 32
5) x = 11
Step-by-step explanation:
Answer:
Step-by-step explanation:
11. -1= (5+x)/6 : to get rid of the 6 on the bottom multiply to both sides.
-6=5+x : subtract 5 to both sides
-11 = x
12. 2/3x + 2 = -4 : subtract the 2 to both sides
2/3x = -6 : divide 2/3 to both sides
x= -6/(2/3)
x=-9
13. 7x+2.5=-4.5 : subtract 2.5 to both sides
7x= -7 : divide by 7 to both sides
x= -1
14. 8-3/8x= -4 : subtract 8 to both sides
-3/8x = -12 : divide both sides by -3/8
x=32 : two negatives make a positive
15. -3x - 5 = -38 : add 5 to both sides
-3x=-33 : divide both sides by -3
x= 11 : two negatives make a positive

Step-by-step explanation:
On a number line lets say it goes from 0 to 10 on the right side or 0 to -10 on the left side.
-2 is closer to 0 on the number line rather than -9
-9 is NOT greater than -2
-2 IS GREATER than -9

Answer:
The answer is A
Step-by-step explanation:
y=mx+b is the point slope form and is the form that is used on the equation.
The slope is mx, or in this case 1x. If you're simply looking for a shift in the line, then the slope has to be the same, so we know that b is not the answer. The y-intercept is b, or as the problem's equation shows, 2. The y-intercept is where the line crosses the y-axis (the vertical axis). Since you're looking for a shift downwards, you need the y-intercept to be lower than 2. The only one that matches that is option A.
Hope this helps!

write each expression without using the absolute value symbol |14-(6-x)|
THIS IS 15 POINTS PLSSSSSS HELP
Answer:We can rewrite the expression |14-(6-x)| as follows:
When (6-x) is positive, 14-(6-x) = 14-6+x = x+8
When (6-x) is negative, 14-(6-x) = 14-6+x = x+8
Therefore, we can write the expression without the absolute value symbol as:
x+8
Step-by-step explanation: We have try the two cases when 6-x is negative and when it s positive
