if two rectangles have the same perimeter, do they have to be congruent??
Answer:
No they do not have to be congruent.
Two rectangles with the same perimeter but may not be congruent, because the length and width dimensions of each may be different.

The midpoint of AB is M(3,-2). If the coordinates of A are (1, -3),
what are the coordinates of B?
Answer:
23 just took the test
Step-by-step explanation:
Answer:
B(5,-1)
Step-by-step explanation:
The formula for finding the midpoint of any line is: [ (x1+x2) / 2 ] , [ (y1+y2) / 2 ] .So, x1=1 and x2=x. And y1=-3 and y2=y.
So,
(1+x)/2=3, then manipulating it gives x=5.
And,
(-3+y)/2=-2, then manipulating the equation gives y=-1.
Hence B(5,-1)

O y = 2x + 2
O y = 2x
O y = 4x + 2
Answer:
y=2x
Step-by-step explanation:
we can set x=number of week, and y=inches
as you can see, 1 week-> x=1 :y=2(1) = 2 inches
2 week-> x=2 :y=2(2)=4 inches
**if we substitute x to y = 2x + 2 and y = 4x + 2, it will not works.

What was the original price of an MP3 player that is advertised as on sale for 25%
off and the sale price is $60?
can i get an explanation, please :)
Answer:
$80
Step-by-step explanation:
the original price (in percent) = 100%
the discount (25% off) = - 25%
_________________
the sale price (in percent) = 75% =>
equal to $60
so, the original price =
100/75 × $60 = $80
Now
Cost price be x.[tex]\\ \rm\longmapsto 100-25=75\%[/tex]
75% of x=60[tex]\\ \rm\longmapsto \dfrac{75}{100}x=60[/tex]

[tex] \sqrt{50} + \sqrt[]{18} - 8 \sqrt[]{2} [/tex]
Answer:
[tex] \sqrt{50} + \sqrt{18} - 8 \sqrt{2} \\ \\ 5 \sqrt{2} + 3 \sqrt{2} - 8 \sqrt{2} \\ \\ 8 \sqrt{2} - 8 \sqrt{2 } \\ \\ = 0[/tex]
Given the expression:
[tex] \displaystyle \large{ \sqrt{50} + \sqrt{18} - 8 \sqrt{2} }[/tex]
Since we have 2 in the square root from 8√2. We will be converting terms in √2 form so we can. evaluate.
As we know, 50 comes from 5×10 = 5×5×2
and 18 comes from 9×2 = 3×3×2.
[tex] \displaystyle \large{ \sqrt{5 \times 5 \times 2} + \sqrt{3 \times 3 \times 2} - 8 \sqrt{2} }[/tex]
In the square root, if there are two same numbers, we can pull it out as one.
Ex. √5×5 would be 5. Refer to below:
[tex] \displaystyle \large{ \sqrt{a \times a} = \sqrt{ {a}^{2} } = |a| }[/tex]
Since there are two fives and two threes in the square root, we pull these numbers out only one.
[tex] \displaystyle \large{ 5\sqrt{2} + 3 \sqrt{2} - 8 \sqrt{2} }[/tex]
Because these terms have the same square root of 2, we can evaluate 5+3-8.
[tex] \displaystyle \large{ 8 \sqrt{2} - 8 \sqrt{2} } = 0[/tex]
Of course, like term - like term = 0
Hence, the answer is 0.
If x=1/8 what is the value of y when 2/x = y/4
Answer:
y = 64
Step-by-step explanation:
x = 1/8
Substituting x in the equation,
=> 2/(1/8) = y/4
=> 2 x 8 = y/4
=> 16 = y/4
=> y/4 = 16
=> y = 16 x 4
=> y = 64
The value of y will be;
⇒ y = 64
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 2/x = y/4
Now,
Since, The expression is,
⇒ 2/x = y/4
Substitute x = 1/8, we get;
⇒ 2/(1/8) = y /4
⇒ 2 × 8 = y / 4
⇒ 16 × 4 = y
⇒ y = 64
Thus, The value of y = 64

Step-by-step explanation:
81 - 1 1/5x ≤ 55
Subtract 81 from each side
81 -81- 1 1/5x ≤ 55-18
- 1 1/5x ≤ -26
Change the mixed number to an improper fraction
-(5*1+1)/5 x ≤ -26
-6/5 x ≤ -26
Multiply each side by -5/6, remembering to flip the inequality
-5/6 *-6/5x≥ -26 * -5/6
x≥130/6
Changing back to a mixed number
x≥ 21 2/3
Answer:
Answer: A
Step-by-step explanation:
[tex]81 - 1 \frac{1}{5} x \leqslant 55[/tex]
subtract 81 from both sides:
[tex](81 - 1 \frac{1}{5} x) - 81 \leqslant 55 - 81 \\ \\ - 1 \frac{1}{5} x \leqslant - 26[/tex]
express the mixed fraction into a proper fraction:
[tex] - \frac{6}{5}x \leqslant - 26[/tex]
multiply -5 on both sides:
[tex] ( - \frac{6}{5} x) \times 5 \leqslant ( - 26 \times - 5) \\ \\ 6x \leqslant 130[/tex]
divide all sides by 6:
[tex] \frac{6x}{6} \leqslant \frac{130}{6} \\ \\ x \leqslant 21 \frac{2}{3} [/tex]

As it is impossible to understand who have done what ,
the correct construction should be :
You are given point A, point B and point C.
Construct a line parallel to that line AB passing through point C.
1) Place the compass on point B, and swing an arc that crosses line AB and line BC.
Label the points D and E.
2) Keep the compass at the same width, and place it on point C.
3) Swing an arc that crosses line BC, and label the point F outside the segment [BC] .
4) Open the compass to the width between points D and E.
Keeping the compass at the same width, place it on point F.
5) Swing an arc that intersects the arc created from line BC at point C.
6) Mark the intersection of the two arcs as point G.
7) Draw a line through point C and point G.
You just have to discover who has done that.

The image shows 4 triangular figures, which represent the Sierpinski triangle fractal at 0, 1, 2, and 3 iterations.
The original triangular figure is an equilateral triangle which is entirely shaded. The triangular figure labeled n = 1 is formed by subdividing the original triangle into 4 congruent triangles and removing the middle triangle. The triangular figure for n = 2 is formed by subdividing each of the congruent triangles from the figure labeled n = 1 into 4 congruent triangles and removing the middle triangles.
The triangular figure for n = 3 is formed by subdividing each of the congruent triangle from the figure labeled n = 2 into 4 congruent triangles and removing the middle triangles.

A polynomial function h(x) has a zero of x = 2 + 7i with a multiplicity of one. Certain values of h(x) are given in the following table. x h(x) –5 0 –2 3 –1 –1 1 2 4 0 7 6 10 0 If every real x-intercept of h(x) is shown in the table and each has a multiplicity of one, what is the degree of h(x)? 3
Degree of h(x) is 5 because there are 5 x intercepts
Given :
The function h(x) has a zero of x = 2 + 7i with a multiplicity of one.
Every x intercept has multiplicity 1
Explanation
x intercept x=2+7i has multiplicity one
For complex intercepts occurs in pairs
So another x intercept is x=2-7i
From the given table , when h(x) is 0 then x is the x intercepts
other x intercepts from the given table are -5, 4,10
There are 5 x intercepts with multiplicity one
h(x) has 5 x intercepts . so , the degree of h(x) is 5
