What is -8(2-3w)-5
Please explain!
Answer:
24w - 21
Step-by-step explanation:
-8(2 - 3w) - 5
We first expand the -8
-16 + 24w - 5
We then add -16 to -5
-16 + -5
= -21
We get the 24w, put in in the equation and get 24w - 21
Answer:
24w−21
Step-by-step explanation:
Factoring 24w2+10w-21
The first term is, 24w2 its coefficient is 24 .
The middle term is, +10w its coefficient is 10 .
The last term, "the constant", is -21
Step-1 : Multiply the coefficient of the first term by the constant 24 • -21 = -504
Step-2 : Find two factors of -504 whose sum equals the coefficient of the middle term, which is 10 .
-504 + 1 = -503
-252 + 2 = -250
-168 + 3 = -165
-126 + 4 = -122
-84 + 6 = -78
-72 + 7 = -65
-63 + 8 = -55
-56 + 9 = -47
-42 + 12 = -30
-36 + 14 = -22
-28 + 18 = -10
-24 + 21 = -3
-21 + 24 = 3
-18 + 28 = 10 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -18 and 28
24w2 - 18w + 28w - 21
Step-4 : Add up the first 2 terms, pulling out like factors :
6w • (4w-3)
Add up the last 2 terms, pulling out common factors :
7 • (4w-3)
Step-5 : Add up the four terms of step 4 :
(6w+7) • (4w-3)
Which is the desired factorization

The product of two consecutive even integers is 8. Find the integers.
Note: each set of brackets represents one solution
Answer:
2 and 4
Step-by-step explanation:
you can just try and u'll get 2 and 4
Answer:
-4 and -2 or 2 and 4Step-by-step explanation:
Let the integers be x and x+2
Then we have:
x(x+2) = 8x^2 + 2x = 8x^2 + 2x + 1 = 9(x + 1)^2 = 3^2x + 1 = ± 3x = -1 ± 3x = -4 and x = 2The numbers are:

c) DEF and TRS are similar
Step-by-step explanation:
a) TR/DE = 9/18 = 1/2
RS/EF = 8/16 = 1/2
TS/DF = 5/10 = 1/2
b) E is the smallest angle on the DEF, and it corresponds w the smallest angle on TRS, R. D corresponds to T, and F to S
they r similar figures - u can see it if u tilt TRS counterclockwise nd flip it
c) they r similar bcuz u can see in part a) that they all have proportional side lengths so yea theyre similar
An investment that costs $5,000 will produce annual cash flows of $3,000 for 3 years. Using a required return of 8%, the investment will generate a NPV of $
Answer:
The investment will generate a NPV of $2,731.
Step-by-step explanation:
Cost of an investment (PV) = $5,000
Annual cash flows = $3,000
Period of investment = 3 years
Interest rate of return = 8%
Annuity Factor = 2.577 (for 3 years at 8% per year)
Present value of the annuity = $3,000 * 2.577 = $7,731
NPV = Annuity PV minus PV of investment cost
= $7,731 - $5,000
= $2,731
b) The NPV (net present value) of $2,731 is the difference between the present value of the annual cash flows $7,731 and the investment cost of $5,000. The resulting NPV is positive and the investment should be accepted.
tiana deposited 500 into an account that earns 6% simple interest. how many years will it take for the value of the account to reach 2000?

the cost of 12 kg sugar is $240 what will be the cost of 3 kg sugar
Question:
The cost of 12 kg sugar is $240 what will be the cost of 3 kg sugar.
Given:
Cost of 12 kg sugar = $240To find?
cost of 3 kg sugarAnswer :
To find cost of 3kg sugar first we have to find cost of 1 kg sugar.
Cost of 1 kg sugar = Cost of total no. of sugar ÷Total sugar Cost of 1 kg sugar = $240/12Cost of 1 kg sugar = $20Now Let's find cost of 3 kg sugar
Cost of 3kg sugar = total no of sugar ×Cost of 1 kg sugar
Cost of 3kg sugar = 3×$20
Cost of 3kg sugar = $60

The mean of a distribution is 276, while the median is 276. Which of these
statements is likely to be true about the distribution?
A. It is negatively skewed.
B. It is positively skewed.
C. It is not symmetric.
D. It is not skewed.
Answer:
It is not skewed.
Step-by-step explanation:
When the mean of a distribution is equal to that of its median, the distribution is not skewed.
Here, mean and median of a distribution is 276. It means, both mean and median are same. It would mean that the distribution is not skewed.
Out of the given options, the correct option is (d) "It is not skewed".

explain how to determine if the two expressions are equivalent using x=6 and x=10
8x+40. 8(x+5)
Answer:
Step-by-step explanation:
if they're equivalent, when you plug in either 10 or 6 for x, they should both equal the same.
x=10, 8(10)+40=120.... 8(10+5)=120. so they equal. also test 6
8(6)+40=88. 8(6+5)=88
they are equivalent since they both equal each other, no matter what you plug in. reason being that the 8(x+5) is the factorized version of 8x+40
Answer:
By putting both values of x in the expression, it can be concluded that both expressions are equivalent.
Step-by-step explanation:
The expressions can be evaluated to be equivalent by putting the values given
The expressions are:
8x+40 and 8(x+5)
Putting x = 6 in both
[tex]8x+40\ and\ 8(x+5)\\8(6)+40\ \ ; \ 8(5+6)\\48+40\ \ \ \ ; \ \ 8(11)\\88\ \ \ \ \ \ \ \ \ \ \ ; \ \ 88[/tex]
The values of both expressions are same on x=6
Now putting x = 10
[tex]8x+40\ and\ 8(x+5)\\8(10)+40\ \ ; \ 8(10+6)\\80+40\ \ \ \ ; \ \ 8(16)\\120\ \ \ \ \ \ \ \ \ ; \ \ 120[/tex]
The values of both expressions are same on x = 10
Hence,
By putting both values of x in the expression, it can be concluded that both expressions are equivalent.
