What's the answer to x^2-6x-8?
Answer:
0
Step-by-step explanation:
(x-4)(x-2)=0
If any individual factor on the left side of the equation is equal to 0
the entire expression will be equal to 0
Set the first factor equal to 0 and solve
x=4
The final solution is all the values that make
(x-4)(x-2)=0
x=4,2

A jar had 88 coins. 1/3 of the coins were silver. How many coins were gold?
Answer:
There are 66 gold coins in the jar
Step-by-step explanation:
Let the number of silver coins = X
Then the number of gold coins = 3X (as there are 1/3 number of silver coins as gold)
Total coins =88
Total coins = silver coins + gold coins
Total coins = X + 3X = 88
Total coins = 4X = 88
X = 88/4
X = 22
No. Of silver coins = 22
No. Of gold coins = 3X = 3×22
No. Of gold coins = 3X= 66
Check
Total coins = 3X + X = 88
66+22 = 88
88 = 88
Hope it helps...
Have a great day :P
Answer:
Hello There!!
Step-by-step explanation:
Let the number of silver coins be x and gold coins be 3x which add up to 4x. Make an expression and add 88 with 4x so 4x=88
x=22(88÷4).
So x=22[silver coins]
3x=66(22×3) [gold coins]
hope this helps,have a great day!!

A local men's clothing store is being sold. From a previous inventory analysis, the current owners determined that 37% of the merchandise was outdated. The buyers would like a more current estimate of the proportion of items that are outdated. They will choose a random sample from the 100,000 items in the store's inventory in order to determine the proportion of merchandise that is outdated. What size sample do the buyers need in order to be 99% confident that the margin of error of their estimate is about 0.06
ANSWER:
the answer is
factor by grouping
3n^3 - 12n^2 + 2n - 8
(show the work pls..)
Answer:
The answer will be ( n - 4 ) ( 3n² + 2 ).
Step-by-step explanation:
1) Factor out common terms in the first two terms, then in the last two terms.
[tex] {3n}^{2} (n - 4) + 2(n - 4)[/tex]
2) Factor out the common term n - 4.
[tex](n - 4)( {3n}^{2} + 2)[/tex]
Therefor, the answer is ( n - 4 ) ( 3n² + 2 ).

Determine the missing side length:
I will give 25 points for the answer!!!!!!!!
Answer:
3
Step-by-step explanation:
Use Pythagorean theorem
Base²+ altitude² = hypotenuse²
Base² + (√3)² = (2√3)²
Base² + √3 *√3 = 2√3 *2√3
Base² + 3 = 4*3
Base² + 3 = 12
Base² = 12 - 3
Base² = 9
Base = [tex]\sqrt{9}=\sqrt{3*3} =3[/tex]
Find the distance between the pair of points. (4,1) and (9,6)
Answer:
5√2 or 7.07 units
Step-by-step explanation:
To find the distance between two points, we want to use the distance formula: d = √[(x₂ - x₁)² + (y₂ - y₁)²]
Plug in the given values of (4,1) and (9,6)
d = √[(x₂ - x₁)² + (y₂ - y₁)²]
d = √[(9 - 4)² + (6 - 1)²]
Simplify the parentheses.
d = √[(5)² + (5)²]
Simplify the exponents.
d = √[25 + 25]
Add.
d = √[50]
Evaluate the radical.
5√2 or 7.07
Round the decimal.
5√2 or 7.07 units

Yolanda ha comprado un coche por 8.200 euros. Lo ha pagado en tres partes. Primero pagó un 60% del valor del coche, después el 25% y por ultimo el resto ¿ cuánto pagó Yolanda la última vez?
Answer:
1.230 euros
Step-by-step explanation:
De la pregunta anterior se nos dice que:
Yolanda compró un coche por 8.200 euros. Lo ha pagado en tres partes.
Paso 1
Sea el porcentaje de la suma total de dinero = 100%
Primero pagó el 60% del valor del auto, luego el 25% y finalmente el resto.
Dejemos que el resto esté representado por x
Por eso;
Primera parte + Segunda parte + Tercera parte = 100%
60% + 25% + x = 100%
x = 100% - (60% + 25%)
x = 100% - 85%
x = 15%
Paso 2
¿Cuánto pagó Yolanda la última vez?
La última vez = Tercera parte y esto se calcula como:
15% de 8.200 euros
= 15/100 × 8.200 euros
= 1.230 euros
Yolanda pagó 1.230 euros la última vez.

Find the area of the polygon.
Answer: 72
Step-by-step explanation: 6*2=12 6*10=60 Normally you would divide by 2 to get triangles but since there are two of each, you don't.
Answer:
Solution given:
diagonal 1=AC=6+6=12units
diagonal 2=BD=2+10=12units
area of polygon (rhombus)=½*(diagonal 1*diagonal 2)
=½(12*12)=12*6=72square units
Area=72square units

please hurry i have 5mins
Answer: I think its A
Step-by-step explanation:
The given function is increasing from 1 to ∞. Therefore, option A is the correct answer.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
From the given graph, the vertex is (1, -2)
For a function y = f(x), if the value of y increases on increasing the value of x, then the function is an increasing function.
Here, the function is increasing from 1 to infinity.
Therefore, option A is the correct answer.
