Find (-21)+(-13)+20.
Answer:
14
Step-by-step explanation:
-21+-13+20=14
This is true because when subtracting negatives by negatives you pretty much add them and then when you add a positive to a negative you are technically removing the negative by the amount you are adding.
In short its kind of like using inverse operation in a way.
Hope this helps and have a nice day

Write a polynomial in standard form with the zeros –4, 0, 1, and 4.
Answer:
uhhm
Step-by-step explanation:
....
The required polynomial in standard form with zeros –4, 0, 1, and 4 is x⁴- x³ - 16x²+16x
Polynomial functions are functions that have a leading variable of 3 and above.
Given the zeros of a polynomial as -4, 0, 1, and 4, their corresponding factors will be:
(x+4)), x-0, x-1 and x - 4
To get the polynomial function required, we will take the product of the factors as shown:
= x(x-1)(x+4)(x-4)
= (x²-x)(x²-4²) (Note that (x+4)(x-4) is from different of two square)
f(x)= x⁴-16x²-x³+16x
Rearranging
f(x) = x⁴- x³ - 16x²+16x
Hence the function x⁴- x³ - 16x²+16x gives the required polynomial in standard form.

a submarine travels at an elevation of -75 3/4 ft relative to sea level then its elevation changes by - 16 3/8 what is the new elevation of the submarine
Answer:
[tex]New = -92\frac{1}{8}[/tex]
Step-by-step explanation:
Given:
[tex]x = -75\frac{3}{4}[/tex] --- Position
[tex]\triangle x = -16\frac{3}{8}[/tex] --- Change
Required
Find the new position
The new position is calculated as:
[tex]New = x + \triangle x[/tex]
[tex]New = -75\frac{3}{4} - 16\frac{3}{8}[/tex]
[tex]New = -75.75 - 16.375[/tex]
[tex]New = -92.125[/tex]
[tex]New = -92\frac{125}{1000}[/tex]
[tex]New = -92\frac{1}{8}[/tex]

the area of a room is 55.929 square meters if its width is 5.43 meters, what is its length
Answer:
10.3m
Step-by-step explanation:
area of a rectangle is width times length, so you have to rearrange the equation
55.929 ÷ 5.43 = 10.3
Answer:
10.3 meters
Step-by-step explanation:
Area = length x width
55.929 = ? x 5.43
Divide 5.43 from 55.929
55.929/5.43 = 10.3 meters
Check = 10.3 x 5.43 = 55.929

Neda sells televisions. She earns a fixed amount for each television and an additional $15 if
the buyer gets an extended warranty. If Neda sells 19 televisions with extended warranties, she
earns $1,615. How much is the fixed amount Neda earns for each television?
Answer:
$70.
Step-by-step explanation:
Since Neda sells televisions, and she earns a fixed amount for each television and an additional $ 15 if the buyer gets an extended warranty, if Neda sold 19 televisions with extended warranties and earned $ 1,615, to determine how much is the fixed amount Neda earns for each television must perform the following calculation:
(19 x 15) + X = 1615
285 + X = 1615
X = 1330
1330/19 = 70
Thus, the fixed amount Neda receives for each television is $70.
Answer: $70
Step-by-step explanation:
Since Neda sells televisions, and she earns a fixed amount for each television and an additional $ 15 if the buyer gets an extended warranty, if Neda sold 19 televisions with extended warranties and earned $ 1,615, to determine how much is the fixed amount Neda earns for each television must perform the following calculation:
(19 x 15) + X = 1615
285 + X = 1615
After this step, you can see that the x is already isolated and no number next to it. This is a good thing because you only need to subtract 285 on both sides.
x = 1330
Then...
1330/19 = 70.
Thus, the fixed amount Neda receives for each television is $70.
