What is the product?
3x³(2x² +4x+1)
O 2x +4Xô + xô
O
6x¹0+12x5+3x5
O 6x² + 12x6 +5
O 3x5+2x² + 4x+1
Answer:
6x⁵+12x⁴+3x³
Step-by-step explanation:
3x³(2x² + 4x + 1) = 3x³ × (2x² + 4x + 1)
therefore
3x³(2x² + 4x + 1) =
(3x³ × 2x²) + (3x³ × 4x) + (3x³ × 1)
*NOTE: for the brackets the multiplication law of indices is applied, i.e:
nª × n^b = n^a+b therefore
x³ × x² = x^3+2 = x⁵
x³ × x = x^3+1 = x⁴
x³ × x⁰ = x^3+0 = x³
*Note the quoeficents multiple each other, i.e:
3 × 2 = 6
3 × 4 = 12
3 × 1 = 3
so:
= 6x⁵ + 12x⁴ + 3x³
Make x the subject to this formula 4x + 3y =2
4x+3y=2
4x=2-3y
x= 2/4 - 3/4 y
x= 1/2- 3/4y
(x= 0.5 - 0.75y)
[tex]\boxed{ \ \sf x=\dfrac{2-3y}{4} \ }[/tex]
Explanation:[Given]
[tex]\sf \rightarrow 4x + 3y =2[/tex]
[Exchange Sides]
[tex]\sf \rightarrow 4x =2-3y[/tex]
[Divide both sides by 4]
[tex]\sf \rightarrow \dfrac{4x}{4} =\dfrac{2-3y}{4}[/tex]
[Simplify]
[tex]\sf \rightarrow x=\dfrac{2-3y}{4}[/tex]

- 16 + ( - 12 ) - ( - 40 )
Answer:
12
Step-by-step explanation:
Its 12 because when you do -16 + - 40.... then -12 you get =12 There you go
Step-by-step explanation:
Solution ,
Firstly we need to understand that
( - ) × ( - ) = ( + )
( + ) × ( + ) = ( - )
( - ) × ( + ) = ( - )
( + ) × ( - ) = ( - )
Question:
- 16 + ( - 12 ) - ( - 40 )
here ( + ) × ( - ) = ( - )
= - 16 - 12 - ( - 40 )
here ( - ) × ( - ) = ( + )
= - 28 + 40
here the ( + ) has greater variable so....
= + 12
hence 12 is the answer....

There is a population of 15,500 bacteria in a colony. If the number of bacteria doubles every 234 hours, what will
che population be 936 hours from now?
bacteria
Answer:
2,48,000
Step-by-step explanation:
Initial population of bacteria = 15,500Bacteria doubles after every 234 hoursSo, after 0 (zero) hours, no of bacteria = 15,500After 234 hours, no. of bacteria = 2(15,500) = 31,000After 468 hours, no. of bacteria = 2(31,000) = 62,000 (2*234 = 468)After 702 hours, no. of bacteria = 2(62,000) = 124,000 (3*234 = 702)After 936 hours, no. of bacteria = 2(124000) = 2,48,000 (4*234 = 936)Find the sine of ZD.

What is the best predicted value of y for x = 5? Use a = 0.05.
what is the positive solution of x²-36=5×
Answer:
I'm assuming the x at the end is a variable
9, -4
Step-by-step explanation:
If we replace x with 9, we get 81-36=45 which is 45=45 so 9 is one solution.
If we replace x with -4, we get 16-36=-20 which is -20=20 so -4 is the other solution
So, the solutions are 9 and -4.

A box contains 14 books & 7 pieces of dusters. Each piece of duster weighs 0.2 pounds each book weighs 1.1 pounds. The box & its contents together weigh 18.25 pounds. How much does the empty box weigh?
Answer:
1.45
Step-by-step explanation:
weight of all books= 14×1.1= 15.4
weight of all duster=7×0.2= 1.4
weight of books and duster= 15.4+1.4=16.8
weight of the empty box = 18.25-16.8=1.45
The incorrect work of a student to solve an equation 2(y + 4) = 4y is shown below:
Step 1: 2(y + 4) = 4y
Step 2: 2y + 6 = 4y
Step 3: 2y = 6
Step 4: y = 3
Which of the following explains how to correct Step 2 and shows the correct value of y?
The equation should be y + 4 = 4y after division by 2: y = 5
The equation should be y + 4 = 4y after division by 2 y = 2
O2 should be distributed as 2y + 8,
O2 should be distributed as 2y + 8, y = 2
Answer:
2(y+4)=4y
2y+8=4y
8=4y-2y
8÷2=y
4=y
Therefore y =4

For part 5 the total value is $1845, for part 6 the total net worth is $3200, and for part 7 the debt to assets value is 0.433.
What is debt?It is defined as the amount one party needs to pay to another party as the first party borrowed an amount that will be credited by the second party. Debt occurs when one party cannot be able to purchase something under normal circumstances.
5)
Total value = 20×30 + 18×40 + 35×15 = $1845
6)
Net worth = (3500 + 300 + 600) - (1000+200) = $3200
7)
Total debt value = 2000+3200 = $5200
Total assets value = 10000+1300+700 = $12000
Debt to assets value = 5200/12000 = 0.433
Similarly, we can find any debt to assets value by using the formula:
Debt to assets value = Total debt/Total assets
Thus, for part 5 the total value is $1845, for part 6 the total net worth is $3200, and for part 7 the debt to assets value is 0.433.

How do you simplify this problem?
Answer:
x/y.
Step-by-step explanation:
Deal with each number or letter at a time:
3 / 3 = 1
x^3/x^2 = x
y^4 / y^5 = y^-1 = 1/y
z / z = 1
So the answer is 1*x * 1/y * 1
= x/y.
