Find the perimeter of a rectangle whose one side measures 20m and diagonal is 29m
Answer:
Option A
Step-by-step explanation:
Answer:
1.You draw the rectangle and label on one side 20m
2.Draw a diagonal line inside the rectangle an label the line as 29m
3.Extract the the newly formed right angled triangle.
4.Find the hypotenuse (a+b=c) of the right angle which will give you the value of the unknown side.
5.Calculate the perimeter which is;
P=S+S+S+S
P= 20m+9m+20m+9m
P=29m+29m
P=58m
True or false? A theorem is a statement that can be easily proved using a
corollary.
Answer:
true
Step-by-step explanation:
Answer: False
explanation:
Its proof is not difficult because it is based on the statement or theorem which has been already proved. For example the fundamental theorem of algebra and its corollary. Therefore, the statement "A corollary is a statement that can be proved using a theorem, but the proof is usually difficult." is false

Answer:
x ≤ - [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Given
3x + 14 ≤ 13 ( subtract 14 from both sides )
3x ≤ - 1 ( divide both sides by 3 )
x ≤ - [tex]\frac{1}{3}[/tex]

y varies inversely with x. If y = 4 when x= -6, find the constant of variation and find the value of y when x= -2
Answer:
constant of variation: k = -24
y = 12 when x = -2
Step-by-step explanation:
y varies inversely with x equation is: y = k/x
where 'k' if the constant of variation
plug in:
4 = k/-6
cross-multiply to get value of 'k' which is -24
plug in:
y = -24/-2
y = 12

x^2+19=10 solve algebraically
4x^2+3=43 solve algebraically
Answer:
[tex]a)\ x_1=-3i,\ x_2 =3i[/tex]
[tex]b)\ x_1=-\sqrt{10},\ x_2=\sqrt{10}[/tex]
Step-by-step explanation:
Given equations:
[tex]a)\ x^2+19=10\\\\b)\ 4x^2+3=43[/tex]
A. x² + 19 = 10
Step 1: Subtract 19 from both sides.
[tex]\\\implies x^2+19-19=10-19\\\\\implies x^2=-9[/tex]
Imaginary number rule: For any positive real number "k", [tex]\sqrt{-k} = i\sqrt{k}[/tex]
Note: Two imaginary (complex) solutions indicate that the graph will not intersect the x-axis. As a result, it has no real roots.
Step 2: Take the square root of both sides (positive and negative roots).
[tex]\\\implies \sqrt{x^2}=\sqrt{-9}\\\\\implies x=\pm\ i\sqrt{9}\\\\\implies x=\pm\ 3i[/tex]
Step 3: Separate the solutions.
[tex]\implies x_1=-3i,\ x_2 =3i[/tex]
----------------------------------------------------------------------------------------------------------------
B. 4x² + 3 = 43
Step 1: Subtract 43 from both sides.
[tex]\\\implies 4x^2++3-3=43-3\\\\\implies 4x^2=40[/tex]
Step 2: Divide both sides by 4.
[tex]\\\implies 4x^2=40\\\\\implies \dfrac{4x^2}4=\dfrac{40}{4}\\\\\implies x^2=10[/tex]
Step 3: Take the square root of both sides (positive and negative roots).
[tex]\\\implies \sqrt{x^2}=\sqrt{10}\\\\\implies x=\pm\ \sqrt{10}[/tex]
Step 4: Separate the solutions.
[tex]\implies x_1=-\sqrt{10},\ x_2=\sqrt{10}[/tex]

Help me please with math
Answer:
B. 1 and 10
Step-by-step explanation:
If A is the set of all integers, choose the set B that will make the following statement false.B ⊆ A
B = {1, 2, 3}
B = {2.5, 3.5, 4.5}
B = {0}
B = {−4, −1, 0, 5, 10}
Answer:
B.
Step-by-step explanation:
The sets {1, 2, 3}, {0}, {-4, -1, 0, 5, 10} only include integers which makes the statement true. Since they are all integers they are all subsets.
Answer {2.5, 3.5, 4.5} does not include integers so therefore it is not a subset making the statement false.

Answer:
C
Step-by-step explanation:
It has to be c by process of elimination the circle has to be filled in and on the #5 and as you can see the only one was C
Answer:
D
Step-by-step explanation:
Solving the inequality
2x + 3 ≤ 5 ( subtract 3 from both sides )
2x ≤ 2 ( divide both sides by 2 )
x ≤ 1
The required number line will have a solid circle at x = 1 and the arrow will be going left.
The only graph with these conditions is D

Do 4x and 15+x have the same value when x is 5?
Are 4x and 15+x equivalent expressions? Explain your reasoning.
Answer:
1. yes 2. no
Step-by-step explanation:
Hi there!
When x is equal to 5, 4x and 15+x have the same value because 4*5= 20 and 15+5 = 20.
4x and 15+x are not equivalent expressions because they cannot be simplified to create the same expression nor will they produce the same answer every time.
I hope this helps!
