A=2(L+W) solving for W
Answer:
A/2 - L = W
Step-by-step explanation:
A=2(L+W)
Divide each side by 2
A/2=2/2(L+W)
A/2=(L+W)
Subtract L
A/2 - L = L+W-L
A/2 - L = W
Answer:
A/2-L=W
Step-by-step explanation:
A/2=L+W
A/2-L=W

Let r= (4+i) and s= 1-i. What is the value of r2-s?
Answer:
r^2 - s = 14 + 9i
Step-by-step explanation:
r^2 = 4^2 + 8i + i^2
r^2 = 16 + 8i - 1
r^2 = 15 + 8i
r^2 - s = 15 + 8i - (1 - i)
r^2 - s = 15 + 8i - 1 + i
r^2 - s = 14 + 9i

Kelly works two jobs. She usually works at a retail store for 5 hours during the day and is paid $18.26 per hour by the store. In the evening she works at a restaurant as a manager for 6 hours and is paid $20.48 per hour. How much does she make on average per hour for the day?
Answer:
19.47 per hour
Step-by-step explanation:
You take 5×18.26 which equals 93.1. Then you take 6×20.48 which equals 214.18. You then add the totals which gives you 122.18. Then you divide the total but the total number of hours she works which is 11 and that gives you 19.47.
Measuring the speed of sound in the ocean is an important part of marine research. One application is the study of climate change. The speed of sound depends on the temperature, salinity, and depth below the surface. For a fixed temperature of 25 degrees Celsius and salinity of 35 parts per thousand, the speed of sound is a function of the depth. At the surface, the speed of sound is 1534 meters per second. For each increase in depth by 1 kilometer, the speed of sound increases by 17 meters per second.
What increase in the speed of sound is caused by a 4-kilometer increase in depth?
Step-by-step explanation:
speed of sound in x depth = 1534 + 17x
4 × 17 = 68 is the increase of sound speed caused by 4 km increase in depth

Replace your expression for h2 in c2=h2 b2-2bx x2.
Answer:
c²=a²+b²-2bx
Step-by-step explanation:
Given,
h²=a²-x²
We need to plug this equation into
c²=h²+b²-2bx+x²
We can replace h² and we get
c²=a²-x²+b²-2bx+x²
Now， we can cancel the terms
c²=a²+b²-2bx
So we get after simplification as
c²=a²+b²-2bx
Answer:
A. C2 = a2 - x2 + b2 - 2bx + x2

Step-by-step explanation:
the answer is in the photo as attached
Answer:
Use the identity:
x³ + y³ + z³ = 3xyz if x + y + z = 0Substitute:
x = a, y = -2b, z = 3cto get
a³ + (-2b)³ + (3c)³ = 3a(-2b)(3c)a³ - 8b³ + 27c³ = --18abcg(x)=x^2-5

- 11 - 2p = 6р +5(p+3)
What would this be?
Answer:
[tex] - 11 - 2p = 6p + 5(p + 3) \\ - 11 - 2p = 6p + 5p + 15 \\ p \: termstogther \\ - 11 - 15 = 6p + 5p + 2p \\ - 26 = 13p \\ p = \frac{ - 26}{13} = -2 \: p = -2\\ thank \: you[/tex]
Answer: p = -2
Step-by-step explanation:
Given expression
-11 - 2p = 6p + 5(p + 3)
Expand parentheses and apply the distributive property
-11 - 2p = 6p + 5p + 15
Combine like terms
-11 - 2p = (6p + 5p) + 15
-11 - 2p = 11p + 15
Add 11 on both sides
-11 - 2p + 11 = 11p + 15 + 11
-2p = 11p + 26
Subtract 11p on both sides
-2p - 11p = 11p + 26 - 11p
-13p = 26
Divide -13 on both sides
-13p / -13 = 26 / -13
[tex]\boxed{p=-2}[/tex]

Thomas invested $40,000. He put part of the money in an account paying 2% interest and the remainder
into stocks paying 3% interest. The total annual income from these investments was $1020. How much
did he invest at each rate?
(show work please)
Answer:
18,000 at 2%
22,000 at 3%
Step-by-step explanation:
x: the amount in account paying 2% interest
y: the amount in stock paying 3% interest
x + y = 40,000
2%. x + 3%. y = 1020
⇒ x = 18,000
y = 22,000

Answer:
Step-by-step explanation:
In 2005, it took 18.54 currency units to equal the value of 1 currency unit in 1915. In 1990, it took only 13.30 currency units to equal the value of 1 currency unit in
1915. The amount it takes to equal the value of 1 currency unit in 1915 can be estimated by the linear function V given by V(x) = 0.3584x + 13.9132, where x is the
number of years since 1990. Thus, V(11) gives the amount it took in 2001 to equal the value of 1 currency unit in 1915. Complete parts (a) and (b) below.
a) Use this function to predict the amount it will take in 2008 and in 2017 to equal the value of 1 currency unit in 1915.
In 2008, it will take currency units.
(Round to two decimal places as needed.)
Answer:
2008 - 1990 = 18
x = 18
v(x) = 0.3584x + 13.9132
= 0.3584 × 18 + 13.9132
= 6.4512 + 13.9132 = 20.3644 = 20.36
in 2017
2017 - 1990 = 27
= 9.6768 + 13.9132 = 23.59
