Answer:
No, she is wrong
Step-by-step explanation:
(4x - 6)^2 can be write as
(4x -6) ( 4x-6)
16x^2 - 24x -24x + 36
16x^2 -48x + 36
So, she is wrong!
Hey there!
(4x - 6)^2
= (4x - 6)(4x - 6)
FACTOR/DISTRIBUTE
= 4x(4x) + 4x(-6) - 6(4x) - 6(-6)
SIMPLIFY
= 16x^2 - 24x - 24x - 36
COMBINE the LIKE TERMS
= 16x^2 - 48x - 36
Therefore, the answer should be:
16x^2 - 48x - 36
Therefore, your answer should be: “No, because the equation should’ve been 16x^2 - 48x - 36. She didn’t factor the equation correctly”
Good luck with your assignment & enjoy your day!

Help please, it's for a test due at 11:30 est; Determine if (x-6) is a factor of f(x)=2x^4-3x^3+4x-3. Explain.
Answers
Answer:
if we get 0, when we plug the value of f(x) as 6 in f(x) then (x-6) is a factor of f(x)
f(x) = 2x⁴ - 3x³ + 4x - 3f(6) = 2×6⁴ - 3×6³ + 4×6 - 3f(6) = 2592 - 638 + 24 - 3f(6) = 2616 - 641f(6) = 1975f(6) is not equal to 0
then (x-6) is not a factor of f(x) = 2x^4-3x^3+4x-3
If Mrs. Allan's car uses 8 gallons of gas for a 224-mile trip, then, at that rate, how many gallons of gas would the car use for a 560-mile trip?
Answers
Answer:
20 gallons of gas
Step-by-step explanation:
Given that :
8 gallons of gas = 224 mile trip
Miles per gallon of Mrs. Allan's car :
Number of miles / gallons of gas
224 miles / 8 gallons

Convert degrees to radians
Show all the work
2. 45
3. 90
Answers
Answer:
[tex]\frac{\pi }{4}[/tex] and [tex]\frac{\pi }{2}[/tex]
Step-by-step explanation:
To convert from degrees to radians
radian measure = degree measure × [tex]\frac{\pi }{180}[/tex] , then
(2)
radian measure = 45 × [tex]\frac{\pi }{180}[/tex] ( cancel 45 and 180 )
= [tex]\frac{\pi }{4}[/tex]
(3)
radian measure = 90 × [tex]\frac{\pi }{180}[/tex] ( cancel 90 and 180 )
= [tex]\frac{\pi }{2}[/tex]

A international company has 26,700 employees in one country. If this represents 31.6% of the company's employees,how many employees does it have in total
Answers
Answer:
79762
Step-by-step explanation:
Total number of employees in one country=26,700
Let X= Total number of the company's employees in all countries
31.6% of ( Total number of the company's employees in all countries)=26,700
=[( 31.6/100) × X)] =26,700
Making X subject of the formula we have
X= [(26,700)/( 33.6/100)]
= [26800/0.336]
= 79762 ( approximately)
Hence, Total number of the company's employees in all countries is 79762

Answers
Complete question :
Stacy has a spinner (1 - 4) and a number cube (1 - 6) after spinning and rolling the number cube she will add two number what is the probability that the sum of the numbers from the spinner and number cube will be 3 or 4
Answer:
5 /24
Step-by-step explanation:
The sample space for the sun of the outcome of the spinner and rolled number cube ;
Sample space = total possible outcomes = 6 * 4 = 24
Required outcome = sum equals 3 or 4 = 5
P(obtaining a sum of 3 or 4) = required outcome / Total possible outcomes
P(obtaining a sum of 3 or 4) = 5 /24

Answer:
7/10 pi (radians)
Step-by-step explanation:
The formula for sector area is (angle * r^2)/2
140pi = angle*r^2/2
multiply both sides by 2
280pi = angle * r^2
r = 20 cm (substitute)
280pi = angle * (20)^2
280pi = angle * 400
Divide both sides by 400
7/10 pi = angle

The three angles of a quadrilateral are 55,73,105 what is the fourth angle
Answers
Answer:
x = 127°
Step-by-step explanation:
Let A, B and C be the three angles of a quadrilateral such that they are 55, 73, 105 respectively.
We know that, the sum of angles of a quadrilateral is equal to 360°. Let fourth angle be x.
55+73+105+x = 360
233+x=360
x = 360-233
x = 127°
So, the fourth angle is equal to 127°.
