Answer:
60inches
Step-by-step explanation:
3 times 4 equals 12. 12 times 5 equals 60. so the volume should be 60 inches.
Answer:
60in squared
Step-By-Step explination:
A= L x W x H
A= 3 x 4 x 5
A= 12 x 5
A = 60in

False
Step-by-step explanation:
2 is next to a variable making it a coefficient.
Answer:
False
Step-by-step explanation:
The constant is 8 because it stands alone and has a fixed value 2 does not stand alone and does not have a fixed value
i have to solve for H
Answer:
h = [tex]\frac{3v}{\pi r^{2} }[/tex]
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Another submarine's descent can be represented as `y=-240x`, where u is the elevation and x is time in hours. How long will it take this submarine to make the descent (2,100 feet below the surface)?
Answer:
The time it will take is 8hours 45mins.
Step-by-step explanation:
Since y = –240x represents a submarine descent. We are looking for how long, that is the time, it will take for the submarine to make a descent of 2100. We know that y is the elevation, if it is descending it will be in the negative direction, making it -ve.
A descent of 2100 means y = –2100. Hence,
–2100 = –240x
x = –2100/–240 = 8.75hours = 8hours 45minutes. (0.75hours = 3/4hours = 3/4 x 60mins = 45mins).
10) using opposite operations solve for x

will give 100 points
Answer:
x=28
m<ACD=68°
Step-by-step explanation:
2x+(180-124)+(180-4x)=180
-2x+236=180
-2x=180-236
-2x=-56
x=28
m<ACD=180-4x=180-4(28)=180-112=68
Answer:
The answer is <ACD = 68°
Step-by-step explanation:
Using the property that the sum of interior angles in a triangle is equal 180°,we have:
<DAC + <ACD + <ADC = 180°
[tex]2x + (180 - 4x) + 56 = 180 \\ - 2x + 56 = 0 \\ 2x = 56 \\ x = \frac{56}{2 } \\ x = 28[/tex]
Finally, calculating the angle <ACD, we have:
<ACD = 180 - 4x
<ACD = 180 - 4 . 28
<ACD = 180 - 112
ACD = 68°

please help!!!!! i’ve been stuck on this question
Answer:
30
Step-by-step explanation:
The angle for BOF is going to be 180.
So if the angle for COF is 150, then COB is going to be the complement angle.
This means it's 180 - 150 = 30.
4x + 5 + 3x – 12 =
A.9x-9
B.7x+7
C.7x-7
Answer:
7x - 7
Step-by-step explanation:
In this equation you are going to add like terms.
The like terms you have are the terms with x and then the terms without the x.
So 4x + 3x = 7x
5 - 12 = -7
So your answer is 7x-7
Expand and simplify 7a + 4(a-2b)
Help please :)

2(3x−4)+14>−2(−3x−5)+4x
Answer:
x<−1
Step-by-step explanation:
Answer:
x < -1
2(3x - 4) + 14 > -2(-3x - 5) + 4x
<=> 6x - 8 + 14 > 2(3x + 5) + 4x
<=> 6x + 6 > 6x + 10 + 4x
<=> 4x + 4 < 0
<=> 4x < -4
<=> x < -1
Solve for x.
6x + 10 = 52
Answer:
7
Step-by-step explanation:
well let’s just think that there’s already 10. let’s ignore the 10 for later.
now let’s think about 6x. of course the x is unknown (variable) which we have to find, so what you want to do, (easy way) think of every multiple of the number 6. so that of course includes 6, 12, 18... etc. now if you continue, you will get to the number 42. now it might not click right there but 42... is what we need since we already have the 10. since 42 + 10 = 52, now we just need to find out what 42 divided by 6 is... 7! 7x6 or 7(6) is 42, plus the starting 10 is 52!
therefore, x = 7.

Name this polynomial by its degree: 3x² + 5x-3
Answer:
[tex]\boxed{\textsf {The given polynomial is a quadratic polynomial. }}[/tex]
Step-by-step explanation:
A polynomial is given to us and we need to make the polynomial by its degree . Here the given polynomial is 3x² + 5x -3 .
[tex]\sf\implies p(x)= 3x^2+5x-3 [/tex]
So here we can see that the highest power of the variable in the given polynomial is 2 . So the polynomial is a quadratic polynomial .
★ More to Know :-
When we equate this quadratic polynomial with 0 , it becomes a quadratic equation.
That is ,
[tex]\sf\implies p(x)= 3x^2+5x-3=0[/tex]
This is done in order to find the zeroes of the polynomial. The zeroes of the polynomial are the values for which the polynomial becomes 0 .

Evaluate the expression. √9 =?
rick believes the two expressions 4(3a-3) +2a and 14a-3 are equivalent. is he correct? explain why or why not?
Answer:
no
Step-by-step explanation:
4(3a-3)+2a when you expand youget
((4x3a)-(4x3)) + 2a = 12a - 12 + 2a then we collect the like term first 12a + 2a - 12
14a -12
therefore 14a - 12 is not equal to 14a- 3

5/7x - 14 = -22. Find x.
Answer:
x = -56/5, -11 1/5, or -11.2
Step-by-step explanation:
5/7x - 14 = -22
5x -98 = -154
5x = -154 + 98
5x = -56
x = -56/5, -11 1/5, or -11.2
Answer:
x= -11.2
Step-by-step explanation:
5/7x-14=-22
+14 +14 Add 14 on both sides
5/7x = -8
(7/5)*5/7x = -8*(7/5) Multiply by the reciprocal on both sides to leave x alone
x= -11.2 Answer

Step-by-step explanation:
Find the product. (2f – 1)^2 =
Answer: 4f^2 -4f+1
Step-by-step explanation:
2f-1)^2
This is equal to
(2f-1) * (2f-1)
FOIL
first: 2f*2f = 4f^2
outer: 2f*-1 = -2f
inner: -1*2f = -2f
Last = -1*-1 = 1
Add them together: = 4f^2 -2f-2f+1
Combine like terms 4f^2 -4f+1
Answer:
(2f-1)(2f-1)
2f^2-2f-2f+1
2f^2-4f+1
