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.

Find the circumference of the circle. Use 3.14 for π. Round to the nearest hundredth, if necessary.
Answer:
14.45
Step-by-step explanation:
Since the solution in this case is C=π(d)/Circumference=pie * diameter you insert 3.14 for pie and 4.6 for the diameter than multiply them together to get 14.444 and it said to round to the nearest hundredth if necessary so now its 14.45. Hope this helps!

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 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

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

Step-by-step explanation:
fill in blanks to write the function when x=3 h(x)=-4-7, when x=3:
h(__)=__
Answer:
h(x)= -4x-7, when x=3
Answer= h(3)= -19
Step-by-step explanation:
Substitute 3 for x in the function and simplify:
h(x) = -4x – 7
h(3) = -4(3) – 7
= -12 – 7
= -19
The value of the function h(x) = -4x - 7 at x = 3 will be -19.
What is function ?The function is defined as a relation between a set of inputs having one output each.
We have,
h(x) = -4x - 7,
So,
When
x = 3
So,
Substituting x = 3 in the given function,
i.e.
h(x) = -4x - 7
We get,
h(3) = -4 * 3 - 7
h(3) = -12 - 7
So,
h(3) = -19
So, the given function at x = 3 is -19.
Hence, we can say that the value of the function h(x) = -4x - 7 at x = 3 will be -19.

volume = pi r^2 h
or, 190 = pi (3.2)^2 h
or, 190/10.24 = pi h
or, 18.56 = 22/7 h
or, 18.56×7/22 = h
