Solve this x²- 3x²- 9x + 27
A. (x + 1)(x - 4)(x + 2)
B. (x + 3)(x - 2)(x + 1)
C. (x - 3)(x + 3)(x - 3)
D. (x - 1)(x + 4)(x - 2)
Answer:
C.
Step-by-step explanation:
I think the first term in the question should be x^3.
It is C because if we multiply the second numbers in the parentheses, -3 * +3 * -3 = + 27.
please solve thanks tyyy
Step-by-step explanation:
x = 1/2 Arc AB ( Relation between inscribed angle and corresponding arc)
x = 1/ 2 * 124
x = 62°
y = x ( Inscribed angles on standing on same arc are equal)
y = 62°
Hope it will help :)

Solve the simultaneous equations.
Please help.
Answer:
the answer is x= 5 and y = 1.5
Here we have been given with two equations and we will solve them by elimination by substitution method inorder to get the value of x and y.
5x - 4y = 19 (Equation No 1)x + 2y = 8 (Equation No 2)★ From Equation No 2 :-
>> x + 2y = 8
>> x = 8 - 2y
★ In Equation No 1 :-
Substituting here the value of x which we got above as (8 - 2y).
>> 5x - 4y = 19
>> 5 (8 - 2y) - 4y = 19
>> 40 - 10y - 4y = 19
>> 40 - 14y = 19
>> -14y = 19 - 40
>> -14y = -21
>> 14y = 21
>> y = 21 / 14
>> y = 1.5
★ Finding out value of x :-
>> x = 8 - 2y
>> x = 8 - 2 (1.5)
>> x = 8 - 2 × 1.5
>> x = 8 - 3
>> x = 5

Which expression is equivalent -6(-2/3+2x0
1. -4-12x
2. -4+2x
3. 4-12x
4. 4+12x
Answer:
3
Step-by-step explanation:
Answer:
Number 3
Step-by-step explanation:
-6( [tex]\frac{-2}{3}[/tex] + 2x) [distribute -6 to [tex]\frac{-2}{3}[/tex] and 2x]
= (-6 × [tex]\frac{-2}{3}[/tex]) + (-6 × 2x)
= (-6 × [tex]\frac{-1}{3}[/tex] × 2) + (-12x)
= (2 × 2) - 12x
= 4 - 12x

Find the value of x
in the figure below
Answer:
x = 29
Step-by-step explanation:
I think this because they give you 78 degrees. The angle across from it (3x - 9) must equal 78 degrees as well. So solve as (3x - 9) = 78. 78 + 9 is 87. 87 divided by 3 is 29.
Hope it helps and is correct!
Triangle ABC is an isosceles with a base AC. The base angles are 60 degrees. Find the length of the base and the length of the altitude from the vertex angle. The length of each leg is 5

what is the slope of (4,6) and (-6,2)
Answer:
2/5
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(2-6)/(-6-4)
m=-4/-10
simplify
m=2/5
Answer:
Step-by-step explanation:
Slope is m=(y2-y1)/(x2-x1)
m=(2-6)/(-6-4)
m=-4/-10
m=2/5

Distance from the tip to the middle of the turbine = Radius of the circular turbine
Radius of the circular turbine = 32 meters
Circumference of the circular turbine = distance the turbine will travel in one revolution
We know that :
[tex]\tt \: \color{hotpink}circumference \: of \: a \: circle \color{plum}= 2\pi r[/tex]
Circumference of the circular turbine :
[tex] = \tt2 \times \frac{22}{7} \times 32 [/tex]
[tex] = \tt\frac{2 \times 22}{7} \times 32[/tex]
[tex] =\tt \frac{44}{7} \times 32[/tex]
[tex] =\tt \frac{44 \times 32}{7} [/tex]
[tex] =\tt \frac{1408}{7} [/tex]
[tex]\color{plum} =\tt 201.06 \: m[/tex]
▪︎201.06 m can be roughly rounded off to 200.96.
▪︎Thus, the distance the turbine will cover in one revolution = 200.96 m
▪︎Therefore, the correct option is (A) 200.96
The circle graph represents the number of teenagers at a high school who play video games. If 1,619 students go to the school,
about how many students do not play video games?
A. 72 students
B. 360 students
C. 454 students
D. 1.165 students
Answer:
C. 454 students
Step-by-step explanation:
Students who play video games = 259°
Students who don't play video games = 360° - 259°
= 101°
Students who don't play video games = 101°/360° * 1,619
= 0.2805555555555 × 1,619
= 454.219 students
Approximately 454 students
C. 454 students
Subtract: (-2x^4-4y^3+4z^3+6)-(-9x^4-3y^3+4z^3+9)
Answer:
Step-by-step explanation:
(-2x⁴ - 4y³ + 4z³ + 6) - (-9x⁴ - 3y³ + 4z³ + 9)
= -2x⁴ - 4y³ + 4z³ + 6 + 9x⁴ + 3y³ - 4z³ - 9
= -2x⁴ + 9x⁴ - 4y³ + 3y³ + 4z³ - 4z³ + 6 - 9
= 7x⁴ - y³ + 0 - 3
= 7x⁴ - y³ - 3

Ir (2p-1,p) is a solution of the equation 9y + 12 = 10x, then find the value of p
Answer:
p = 2
Step-by-step explanation:
Since, (2p-1,p) is a solution of the equation 9y + 12 = 10x.
Therefore, plug x = 2p - 1 & y = p in the above equation.
9p + 12 = 10(2p - 1)
9p + 12 = 20p - 10
12 + 10 = 20p - 9p
22 = 11p
p = 22/11
p = 2

This circle has a radius of 12 millimeters and is divided into 8 equal sections. In terms of pi,
what is the area of 1 section of this circle?
Answer:
A = 18π mm²Step-by-step explanation:
Area of a circle: [tex]A_\circ =\pi r^2[/tex] where r is a radius of this circle
8 equal section means area of one is: [tex]A=\dfrac{\pi r^2}{8\ }[/tex]
r = 12 mm
[tex]A=\dfrac{\pi\cdot 12^2}{8\ }=\dfrac{144\pi}{8}=18\pi[/tex]
