Answer:
0
Step-by-step explanation:
(4x-7)+(7-4x)
cancels each other
which makes it zero
Given pair of expression :
[tex] \longrightarrow \sf {(4x -7) \: and \: (7-4x) } [/tex]
Solution :
Firstly put the sign of addition (+) at the place of and.
[tex] \longrightarrow \sf {(4x -7) + (7-4x) } [/tex]
Now, remove the brackets.
[tex] \longrightarrow \sf {4x -7 + 7-4x } [/tex]
Group like terms. Here, 4x and -4x ; -7 and +7 are like terms.
[tex] \longrightarrow \sf {\cancel{4x -4x} \cancel{ -7 + 7}} [/tex]
[tex] \implies \sf \red {0 } [/tex]
So, the answer is 0.

2. ALMN and APMN are shown below. What additional information is necessary to prove
ALMN = APMN by HL?
Help please!!!
Answer:
The additional information necessary is option;
D. [tex]\overline {MN}[/tex] ⊥ [tex]\overline {LP}[/tex]
Step-by-step explanation:
From the given figure, we have;
Given that ML ≅ MP,
The Hypotenuse Leg HL theorem of congruency is used to prove that a given number of right triangles based on the lengths of their hypotenuse and one of the legs. It states that two or more right triangles are congruent if they have equal lengths of both their corresponding hypotenuse side and one leg
To prove that ΔLMN and ΔPMN are congruent by HL, we will also be required to prove that ΔLMN and ΔPMN are right triangles
For ΔLMN and ΔPMN to be right triangles, the angles, ∠LNM and ∠PNM should be right angles = 90°
With ∠LNM = ∠PNM = 90°, then, line [tex]\overline {MN}[/tex] is perpendicular to line [tex]\overline {LP}[/tex] or [tex]\overline {MN}[/tex] ⊥ [tex]\overline {LP}[/tex]
Therefore, the additional information necessary to prove that ΔLMN ≅ ΔPMN by HL is [tex]\overline {MN}[/tex] ⊥ [tex]\overline {LP}[/tex].

Here is the problem: 5 times the square of a number and 2 is 45.
Answer:
Step-by-step explanation:
We must follow order of operations rules here.
Let the number be x. Then 5x^2 + 2 = 45. No parentheses needed here.
Then 5x^2 = 45, and x = ±9

Below are two parallel lines with a third line intersecting them.
If you can’t see it the number is 81
Answer:
x° = 81°
Step-by-step explanation:
From the diagram, we have;
Two parallel lines crossed by a common transversal
Therefore, the corresponding angle formed by the transversal and each of the parallel lines are equal
The given angle = 81°
The alternate exterior angle to the given angle = x°
When two parallel lines are crossed by a common transversal, the alternate exterior angles are equal
∴ x° = 81°.
Factor out the GCF from the given polynomial. 10^3 + 16^2 - 18x 10^3 + 16^2 - 18x = (Type your answer in factored form.)
Correct question is;
Factor out the GCF from the given polynomial. 10x³ + 16x² - 18x. (Type your answer in factored form.)
Answer:
GCF = 5x² + 8x - 9
Step-by-step explanation:
The given polynomial is;
10x³ + 16x² - 18x
First thing is to inspect the coefficients and see the greatest number that all three can be divided by evenly without remainder.
The greatest number is 2.
Secondly let's inspect the variables to see what we can factor out.
They all contain x. Thus, x is a factor.
Thus, we will divide each term by 2x to obtain the GCF of the polynomial.
GCF = (10x³/2x) + (16x²/2x) - (18x/2x)
GCF = 5x² + 8x - 9

O C. The interquartile range (IQR) for town A, 20°, is greater than the
IQR for town B, 10°.
D. The interquartile ranges (IQRs) for towns A and B are both 20°.
Answer: C
Step-by-step explanation:
just took test
The interquartile range (IQR) for town A, 20°, is greater than the IQR for town B, 10°. The correct option is C.
What is interquartile range?The interquartile range (IQR) is a measure of the spread of the data's middle 50%. It is defined as the difference between the third and first quartiles (Q1). A larger IQR indicates that the data is spread out more.
Looking at the box plots, we can see that the IQR for town A is the distance between the lower and upper quartiles, which is approximately 30 - 20 = 10 degrees.
The IQR for town B is approximately 45 - 35 = 10 degrees.
So, the interquartile range (IQR) for town A, 20°, is greater than the IQR for town B, 10°.
Option A is incorrect because the IQR for town B exceeds 46o. Option B is incorrect because the box plots do not include the standard deviation. Option D is incorrect because the IQRs for the two towns differ.
Thus, the correct option is C.

Part B: What is the solution to the equations of lines A and B? Explain your answer. (5 points)
Answer:
A. one B. (3, 4)
Step-by-step explanation:
1. A good graph can answer both parts (see attached image).
2. Write equations for the two lines and find a simultaneous solution.
Line A: Slope from (2, 6) to (5, 0) is [tex]m=\frac{6-0}{2-5}=\frac{6}{-3}=-2[/tex]
Using point-slope form [tex]y-y_1=m(x-x_1)[/tex]
[tex]y-6=-2(x-2)\\y-6=-2x+4\\y=-2x+10[/tex]
Line B: Slopt from (6, 6) to (0, 2) is [tex]m=\frac{6-2}{6-0}=\frac{2}{3}[/tex]
Using point-slope form, the equation for Line B is
[tex]y-2=\frac{2}{3}(x-0)\\y=\frac{2}{3}x+2[/tex]
To find the simultaneous solution, set the y's equal.
[tex]-2x+10=\frac{2}{3}x+2\\-6x+30=2x+6\\-8x=-24\\x=3[/tex]

Answer:
EF = 68°
Step-by-step explanation:
If 2 chords of a circle are congruent then the corresponding arcs are congruent.
The central angle FDG is equal in measure to the arc that subtends it
arc FG = 68°
Given EF ≡ FG , then
arc EF ≡ arc FG, so
arc EF = 68°

Aaron's P.E. class is completing a unit on bowling. So every Friday afternoon for the last three weeks, they have bowled one game at a nearby bowling alley. His scores have been 121, 147, and 96. What would he have to bowl next time in order to have a mean score of 128?
Solution:
Let x represent Aaron's fourth and unknown score. To have a mean of 128, the sum of the four scores would have to be divided by 4. To get that sum by itself, multiply it by 4. You also have to multiply the desired mean of 128 by 4. So the sum of the four scores is equal to 128 times 4.
121 + 147 + 96 + x = 128 ∙ 4
• Substitute in the values of the four scores.
364 + x = 512
• Simplify.
364 - 364 + x = 512 - 364
• Subtract 364 from each side of the equation.
x = 148
• Simplify.
Aaron must score a 148 in order to have a mean score of 128.
