Answer:A. 3x^2-2x-1+9x+2x^2-3=5x^2+7x-4
B. 5x^3+4x^2-x-3-5x^2-7x+4=5x^3-x^2-8x+1
C. Polynomials are closed under addition and subtraction...
Step-by-step explanation:
The metric unit of a quantity is simply the unit of measurement of the quantity
The volumes of the crashed tomato cans are 1184 milliliters and 1.184 liters
The volume of the crushed tomato can is given as:

From the question, we have the following conversion ratio

So, the volume in milliliters becomes

Multiply

To convert the unit to liters, we simply divide the volume by 1000.
So, we have:


Hence, the equivalent volumes are 1184 milliliters and 1.184 liters

Answer:
5 units
Step-by-step explanation:
If point T is on the line segment SU, then ST + TU = SU.
Given
TU = 4x + 1
SU = 8
ST = 3x
To get TU, we need to get the value of x first. To get x, we will substitute the given parameters into the formula;
3x+4x+1 = 8
7x+1 = 8
subtract 1 from both sides
7x+1-1 = 8-1
7x = 7
divide both sides by 7
7x/7 = 7/7
x = 1
Substitute x = 1 into the length TU
Since TU = 4x+1
TU = 4(1)+1
TU = 5
Hence the numerical length of TU is 5 units
Firstly, we can look at our givens,
a = 17
b = 22
c = 30
And we are looking for m∠A
Is the Law of Cosines. Now we can solve for our unknown, m∠A. This will give us

Now we can substitute in our given variables.

Then we can plug this into our calculator which will give us
34.19185257 degrees
Now we just have to round to the nearest tenth
This means that the answer is 34.2 degrees
