Answer:

area of recatangle= 4x^3(x^3+3x^2+2x)

=4x^6+12x^5+8x^4

3-5x=2

or, -5x=-1

or, x= 1/5

The value of x is 1/5 for equation 3 – 5x = 2

Two or more expressions with an Equal sign is called as Equation.

The given equation is 3 – 5x = 2

Three minus five times of x equal to two

We need to solve for x

3 – 5x = 2

Subtract 3 from both sides

3-3-5x=2-3

-5x=-1

Divide both sides by -5

x=-1/-5

x equal to one by five

x=1/5

Hence, the value of x is 1/5 for equation 3 – 5x = 2

Answer:

B

Step-by-step explanation:

because 4(x+3)=6x+16 is true

4(-2+3)=6(-2)+16

4(1)= -12+16

4=4

==========================================

Explanation:

1/2 = 0.5

Every 60 days, the amount cuts in half.

We start with 904 grams and after 60 days, we have 904*0.5 = 452 grams left over.

After another 60 days, we have 452*0.5 = 226 grams left over.

-------------

Alternative Method:

We can apply the half-life formula.

y = a*(0.5)^(x/H)

where,

In this case,

When x = 120 days go by, we have....

y = a*(0.5)^(x/H)

y = 904*(0.5)^(x/60)

y = 904*(0.5)^(120/60)

y = 904*(0.5)^(2)

y = 904*(0.25)

y = 226 grams of antimony left over.

This method is preferred over the first method if you have x be some non-multiple of 60, or if x is fairly large.

Answer:

a) 10.5

b) 25.32

Step-by-step explanation:

Plug in 2.3 for n in both equations.

First equation:

5 (2.3 - 2) + 9

5 (0.3) + 9

1.5 + 9

10.5

Second equation:

8 (2.3^2) - 17

8 (5.29) - 17

42.32 - 17

Answer:

no

Step-by-step explanation:

If x = 3 is a zero, then f(3) = 0

f(3)

= 4[tex](3)^{4}[/tex] - 3³ - 52(3)² - 35(3) + 12

= 324 - 27 - 468 - 105 + 12

= - 264

Since f(3) ≠ 0 then x = 3 is not a zero of f(x)

Answer:

y = -2x

Step-by-step explanation:

since the y-int starts at 0, you would go down 2 (negative) and to the right by 1, 2/1=2

use the equation y=mx+b to find the equation of a graph

m is the slope and b is the y-int

you can also use the method rise/run, where in this case, the rise (down when it’s a negative) is -2 and the run (across) is 1

2 represents the change in y and 1 represents the change in x

when finding the equation of a graph, always check the y-axis for the point then start there. that represents your y-int. then you look for a solid point and see how much units away across and up or down it is from the y-int.

in this case, i went to the point (1, -2).

Answer:

h=200

Step-by-step explanation:

h/10+5=25

h/10=20

h=200

h/10 + 5 = 25

Subtract 5 from each side to get h/10 alone.

h/10 + 5 - 5 = 25 - 5

h/10 = 20

Multiply both sides by 10 to get h alone.

h/10 • 10 = 20 • 10

h = 200

h = 200. I hope this helps!

Answer:

The value of Cos(60°) is ½

Step-by-step explanation:

B)as we know

b²=a²+c²-2ac.cos(b)

b=√5²+8²-2.5.8×cos(60°)

b=√25+64-80×½

b=√25+64-40

b=√89-40

b=√49

b=7 (proven)

We have to Prove b=7.

A plane figure with three straight sides and three angles.

As we know,

b²=a²+c²-2ac.cos(b)

b=√5²+8²-2.5.8×cos(60°)

b=√25+64-80×½

b=√25+64-40

b=√89-40

b=√49

b=7 (proven)

Plzzzz give me Brainliest!  

The probability that both erasers chosen were blue is 3/25.

To find the probability that both erasers chosen were blue, we need to determine the favorable outcomes (choosing two blue erasers) and the total possible outcomes.

There are a total of 25 erasers in the cup: 7 red erasers + 4 yellow erasers + 9 blue erasers + 5 green erasers = 25 erasers.

To calculate the probability, we consider the events of choosing a blue eraser without replacement.

For the first pick, there are 9 blue erasers out of 25 total erasers.

After the first blue eraser is chosen, there are 8 blue erasers remaining out of 24 total erasers.

The probability of choosing a blue eraser on the first pick is 9/25.

The probability of choosing a blue eraser on the second pick, without replacement, is 8/24.

To find the probability of both events occurring (both erasers chosen being blue), we multiply the probabilities together:

(9/25) * (8/24) = 72/600 = 6/50 = 3/25

Therefore, the probability that both erasers chosen were blue is 3/25.
