please help me with the math problem and show me how to do these kinds.
Thank you.
Answers
Answer:
The answer is 9
Step-by-step explanation:
for the equation:
move the -6x
x^2 + c - 6x
To find c :
c = (b/2)^2
this means you have to divide the coefficient of x by 2 then square the result

Complete question :
Taylor earns $5 each time she walks her neighbor's dog. She has already earned $25. Write and solve an equation to find out how many more times Taylor needs to walk the dog to earn enough to buy a bike that costs $83.
Answer:
12
Step-by-step explanation:
Amount earned for walking dog = $5 per walk
Amount already earned = $25
How many more times dog needs to be walked to buy a bike which costs $83
Target amount = 83
(Target amount - already earned amount) / amount earned per Walk
(83 - 25) / 5
58 / 5
= 11.6
Hence, Taylor needs to walk her neighbor's dog 12 more times

Answer:
-4/3 m/s
Step-by-step explanation:
Using Pythagoras :
a² = x² + c²
5² = x² + y² - - - (1)
The horizontal distance x with respect to time t = 1m/sec
dx/dt = 1m/sec
To obtain the vertical height 'y' with respect to time t when x = 4
5² = x² + y²
Wen x = 4
5² = 4² + y²
25 = 16 + y²
y =√(25 - 16)
y = 3
Differentiate (1) with respect to t
x² + y² = 25 - ---- - (1)
2x * dx /dt + 2y dy/dt = 0
dx/dt = 1
x = 4.
y = 3
2(4)(1) + 2(3) * dy/dt = 0
8 + 6dy/dt = 0
6 dy/dt = - 8
dy/dt = - 8/6
dy/dt = - 4/3

Whats double of 8x4?
Answers
Answer:
64
Step-by-step explanation:
cus 8 times 4 is 32 and 32 times 2 is 64
The double of 8 multiplied by 4 is 64. This means that if we multiply 8 by 4 and then multiply the result by 2, we obtain 64. The multiplication operation is performed first (8 * 4 = 32), and then the result is doubled by multiplying it by 2 (2 * 32 = 64).
To find the double of 8 multiplied by 4, we can perform the following calculation:
Double of 8x4 = 2 * (8 * 4)
First, we multiply 8 and 4:
8 * 4 = 32
Next, we multiply the result by 2:
2 * 32 = 64
Therefore, the double of 8 multiplied by 4 is 64. This means that if we multiply 8 by 4 and then multiply the result by 2, we obtain 64. The multiplication operation is performed first (8 * 4 = 32), and then the result is doubled by multiplying it by 2 (2 * 32 = 64).

Each square has a side length of 12 units. Compare the areas of the shaded regions in the 3 figures. Which figure has the largest shaded region? Explain or show your reasoning.
Answers
Answer:They are equal
Step-by-step explanation:
they will add up they are just token apart or in pieces
Three different figures are given. The area of the shaded region of all the figures is the same.
We need to determine the highest shaded area among all.
Now, the area of the square is common to all.
Thus,
[tex]\begin{aligned}\rm{Area\;of\;square}&=12^2\\&=144 \;\rm{units^2}\end{aligned}[/tex]
1). Calculate the shaded area for figure A.
The diameter of the circle is 12 units, hence its radius is 6 units.
Therefore,
[tex]\begin{aligned}\rm{Area\;of\;circle}&=\pi \times 6^2\\&=36 \pi \;\rm{units^2}\end{aligned}[/tex]
[tex]\begin{aligned} \rm{Shaded\; area} &= \rm{Area\; of\; the\; square - Area\; of\; the\; circle}\\&=144-36 \pi \end{aligned}[/tex]
Thus, the area of the shaded region for figure 1 is [tex]114-36 \pi[/tex].
2). Calculate the shaded area for the figure B.
The diameter of the circle is 6 units, hence its radius is 3 units.
Therefore,
[tex]\begin{aligned}\rm{Area\;of\;circle}&=\pi \times 3^2\\&=9 \pi \;\rm{units^2}\end{aligned}[/tex]
[tex]\begin{aligned} \rm{Shaded\; area} &= \rm{Area\; of\; the\; square - 4 \times Area\; of\; the\; circle}\\&=144-36 \pi \end{aligned}[/tex]
Thus, the area of the shaded region for figure 2 is [tex]114-36 \pi[/tex].
3). Calculate the shaded area for figure C.
The diameter of the circle is 4 units, hence its radius is 2 units.
Therefore,
[tex]\begin{aligned}\rm{Area\;of\;circle}&=\pi \times 2^2\\&=4 \pi \;\rm{units^2}\end{aligned}[/tex]
[tex]\begin{aligned} \rm{Shaded\; area} &= \rm{Area\; of\; the\; square - Area\; of\; the\; circle}\\&=144-36 \pi \end{aligned}[/tex]
Thus, the area of the shaded region for figure 3 is [tex]114-36 \pi[/tex].
Therefore, the area of the shaded region of all the figures is the same.
