x^4-25x^2+144 by x-4
Answer:
x^5-25x^3-4x+144/x
Step-by-step explanation:
x^4-25x^2+144 by x-4
Write the division as a fraction
x^4-25x^2+144/x -4
Write all numerators above the common denominator
x^5-25x^3+144-4x/x
Use the commutative property to reorder the terms
x^5-25x^3-4x+144/x

Consider the figure below.
What are the values of x and y?
Answers:
x = 14
y = 14
==========================================
Explanation:
The tickmarks indicate the sides x and y are the same length.
So y = x or x = y
We can use the Pythagorean theorem to say
a^2 + b^2 = c^2
x^2 + y^2 = (14*sqrt(2))^2
x^2 + x^2 = 14^2*(sqrt(2))^2
2x^2 = 196*2
x^2 = 196 ...... divide both sides by 2
x = sqrt(196)
x = 14
This must mean that y = 14 as well.
This triangle is an isosceles right triangle. We also consider it a 45-45-90 triangle because the three angles are 45, 45, and 90 degrees.
For any 45-45-90 triangle, the hypotenuse is always sqrt(2) times the leg length.
hypotenuse = leg*sqrt(2)
A- 105.6 cm2
B- 43.76 cm2
C- 452.16 cm2
Answer:
C. 452.16 cm2
Step-by-step explanation:
A= π r^2 = π · 12^2 ≈ 452.38934 or 452.38
The closest answer to that listed is C
formula:(A = π r²)
π = 3.14

72 is 25% of students that have a cat, how many total students are there?
Answer:
288
Step-by-step explanation:
1. Use the formula: P*T=N
P = percent, T = Total, and N is the other number.
2. So, P*T=N, therefore, 25%*T=72
3. Simplify .25*T=72
4. So get the Total (T) by itself, you have to divide both sides by .25
5. T = 72/.25

5,15,35,65 solve the rule and the next term
Answer:
105
Step-by-step explanation:
Given the sequence of numbers
5,15,35,65
First lets get the common difference
d1 = 15-5 = 10
d2 = 35 - 15 = 20
d3 = 65-35 = 30
We can see that the differences form an arithmetic sequence
10, 20, 30..
Let's get the next term fist
Tn = a + (n-1)d
T4 = 10+(4-1)(10)
T4 = 10 + 3(10)
T4 = 10+30
T4 = 40
This means that the next term of the original sequence will be gotten by adding 40 to the preceding value
Next term = 65 + 40
Next term = 105
Hence the next term is 105

3x + 2y = -9
X – Y = -13
Answer:
x =-7. .y=6
Step-by-step explanation:
3x + 2y = -9
(X – Y = -13)×3
3x + 2y = -9
3x – 3y = -39
5y = 30
y=6
3x +2(6)=-9
3x=-21

A group of students formed a circle during a game.
The circumference of the circle was about 43.96 ft. ,
and the diameter of the circle was 14 ft.
Which expression best represents the value of π?
Answer and Step-by-step explanation:
C = circumference = 43.96
d = diameter = 14
C = [tex]\pi d[/tex]
Divide both sides by d.
[tex]\frac{C}{d} = \pi[/tex]
[tex]\frac{43.96}{14}[/tex] = [tex]\pi[/tex]
3.14 [tex]= \pi[/tex]

i need help on the math question if it's right I'll give brain.
Answer: \frac{2}{5} ; or, write in decimal form: 0.4 .
Step-by-step explanation:
Rewrite as:
_______________________
[tex]\frac{4x}{7} = \frac{8}{35}[/tex] ;
________________________
Now, "Cross-factor multiply":
that is:
_____________________
→ Given: [tex]\frac{a}{b} =\frac{c}{d}[/tex] ;
→ ad = bc ; (b≠0 ; d≠0) ;
_____________________
As such:
4x * 35 = 7 * 8 ;
_______________________
We can divide one side of the equatiuon by "4" ; and one side by "7" :
[tex]\frac{4x*35}{4*7} = \frac{7*8}{4*7}[/tex] ;
_______________________
We can simplify the "left-hand side":
"4/4 = 1 " ; and "35/7 = 5 " ; & we are left with "x * 5" ; or "5x " .
________________________
We can simplify the "right-hand side":
"7/7 = 1 " ; and: "8/4 =2 " ; to get: "2/1" ; which equals "2".
_________________________
So; we have: " 5x = 2 " ; Solve for "x" ;
__________________________
Divide each side of the equation by "5" ; to isolate "x" on one ide of the equation; & to solve for: "x" ;
__________________________
" 5x/5 = 2/5 " ; We cancel out the "5x/5" to "1x"; which equals "x":
→ x = [tex]\frac{2}{5}[/tex] ; or, write in decimal format: "x = 0.4" ;
___________________________
\frac{2}{5}

Answer:
[tex]x = 0.4[/tex]
Step-by-step explanation:
[tex]\frac{7}{4} x \frac{4}{7} = \frac{7}{4} x \frac{8}{35}[/tex]
Reduce the number with the greatest common factor 7
[tex]\frac{1}{4} x 4x= \frac{7}{4}x\frac{8}{35}[/tex]
[tex]x=\frac{7}{4}x\frac{8}{35}[/tex]
[tex]x=7x\frac{2}{35}[/tex]
[tex]x=\frac{2}{5}[/tex]
A.) 15.7in
B.) 31.4in
C.) 40in
D.) 62.8in
Answer:
31.4 in
Step-by-step explanation:
This is a tricky question,
if you observe the shape carefully, you will notice that if you mirror (flip outward) each curve surface of each quardrant, what you will end up with is a complete circle with a radius of 5 inches.
Hence the combined length of all the curved surfaces is simply the circumference of the circle, given by:
Circumference = 2πr
= 2 x 3.14 x 5
= 31.4 in
