Hello there! The value of x is 20 or -20
"20 or - 20" is one answer so you are supposed to answer 20 or -20, not choose only one.
Step-by-step explanation:
[tex] \large{ \frac{ {x}^{2} }{ {5}^{2} } = {4}^{2} }[/tex]
First, we simplify 5² and 4²
[tex] \large{ \frac{ {x}^{2} }{25} = 16}[/tex]
Multiply the whole equation by 25 to get rid of the denominator.
[tex] \large{ \frac{ {x}^{2} }{25} (25) = 16(25)} \\ \large{ {x}^{2} = 400}[/tex]
Square both sides and solve the equation.
[tex] \large{ \sqrt{ {x}^{2} } = \pm{ \sqrt{400} }}[/tex]
Also don't forget to write "plus or minus" symbol when we are solving a quadratic equation by squaring both sides.
[tex] \large{x = \pm{20}}[/tex]

A student simplified the expression (3x^2+2)-(2x^2+4) as x^2+^6 Explain what the student did incorrectly and state the correct answer.
Answer:
x^2 - 2
Step-by-step explanation:
The correct procedure would have been to distribute the negative to the +4 also, so you would have +2 - 4 = -2 so the final answer should have been
x^2 - 2
(3x²+2)-(2x²+4)
write in a different form, remove parentheses
3x²+2-2x²-4
calculate the value of the corresponding terms
x²-2
Answer: Yes, he made a mistake.
A simplified expression would look like this x²-2 and not like this x²+^6.

The school band will sell pizzas to raise money for new uniforms. The supplier charges $97.00 plus $6.00 per pizza. The band members sell the pizza for $8.00 each. Enter and solve an inequality to find how many pizzas the band members will have to sell to make a profit. Let p be the numbers of pizzas sold. The inequality is ? The band members will need to sell at least __. pizzas.
Answer:
49 pizzas
Step-by-step explanation:
Start by writing it as a equation,
P stands for Pizza
6p +97 = 8p
Minus 6p from both sides
97=2p
Divide by 2
P= 48.5
You would need to round up, so it would be 49 pizza

Answer:
the median should be 2.5
Answer:
2.5
Step-by-step explanation:
By taking the dots ploted on the graph we can take those as actual numbers and put them on a line.
0, 1, 1, 2, 2, 2, 3, 3, 3, 4, 4, 5
Now you will take off the numbers until you get to the middle number
0, 1, 1, 2, 2, 2, 3, 3, 3, 4, 4, 5
Because the middle two numbers are 2 and 3, you take the mean of the two numbers.
(2 + 3) / 2
= 2.5

What is the two fifths of the collection pilers, hammers, wrenches, saws.
Answer:
Pliers
Step-by-step explanation:
From the picture attached,
Number of pliers = 4
Number of hammers = 2
Number of wrenches = 2
Number of saws = 2
Total collection of tools = 4 + 2 + 2 + 2 = 10
Since, two fifth means,
[tex]\frac{2}{5}=\frac{2\times 2}{5\times 2}[/tex]
[tex]\frac{2}{5}=\frac{4}{10}[/tex]
That means tool with 4 counts out of total 10 tools will be the answer.
And the answer is pliers.

Answer:
1) AC = 6 cm
2) AB = 16.2 cm ( note that ^{2} is = square and \sqrt{ this is = square root)
3) BC = 12.65cm
Step-by-step explanation:
1) a^{2} + b^{2} = c^{2}
4.8^{2} + 3.6^{2} = AC^{2}
36 = AC^{2}
\sqrt{ }36 = AC
AC = 6
2) a^{2} + b^{2} = c^{2}
AB^{2} + 6.75^{2} = 17.55^{2}
AB^{2} = 308.0025 - 25.5625
AB = \sqrt{ }262.44
AB = 16.2
3) a^{2} + b^{2} = c^{2}
BC^{2} + 6^{2} = 14^{2}
BC^{2} = 196 - 36
BC = \sqrt{ } 160
BC = 12.65

Answer:
option c.........it should be tan(20)=x/15.035
Answer:
d
Step-by-step explanation:
100 points! Look at the picture attached. Random answers and links will be reported
Answer and Step-by-step explanation:
4. We are finding line AC.
AB is congruent to BC because the angles at the top are both 30 because of angle bisector. BD is congruent to BD, so triangles are congruent by SAS theorem. That means AB is congruent to BC by CPCTC (Congruent Parts of Congruent Triangles are Congruent).
With that being said, we can equal the expressions together.
-x + 25 = 3(2x - 8)
-x + 25 = 6x - 24
49 = 7x
7 = x
-(7) + 25 = 18
3(2(7) - 8) = 3(14 - 8) = 3(6) = 18
18 + 18 = 36
AC = 36
6. We are finding measure of angle UTW.
We have another angle bisector, so that side is equal to itself (TV ≅ TV)
We have UV and VW having the same length, so those are congruent.
Since this is a right triangle, these triangles are congruent by the HL (Hypotenuse-Leg) Theorem.
So, now we can equal the angles together.
2x + 3 = 5x - 24
27 = 3x
9 = x
2(9) + 3 = 18 + 3 = 21
5(9) - 24 = 45 - 24 = 21
21 + 21 = 42
m∠UTW = 42

A scale drawing has a scale of 2 cm = 15 m. If the length of something on the drawing is 12 cm, what is the actual length?
Answer: 90
Step-by-step explanation:
Answer:
90m
Step-by-step explanation:
you have to cross multiply.
1) multiply (12 * 15) and multiply 2 * X)
2) you get 180 = 2x
3) to get X alone divide 180 by 2 and you will get 90meters
