Answer:

3( n + [tex]\frac{17}{6}[/tex] )² - [tex]\frac{361}{12}[/tex] = 0

Step-by-step explanation:

3n² = 6 - 17n ⇔ 3n² + 17n - 6 = 0

3( n² + 2 × [tex]\frac{17}{6}[/tex] n + ( [tex]\frac{17}{6}[/tex] )² - ( [tex]\frac{17}{6}[/tex] )² - 2 ) = 0

3( n + [tex]\frac{17}{6}[/tex] )² - 3 × [tex]\frac{289}{36}[/tex] - 6 = 0

3( n + [tex]\frac{17}{6}[/tex] )² - [tex]\frac{361}{12}[/tex] = 0

It’s not letting me comment on the last answer but can someone explain why it’s D??? Like I want to know how to solve the problem on my own.

Step-by-step explanation:

The argument of the complex number z=√2/2 - √2/2i is π/4. The correct option is A.

A complex number is a number system element in mathematics that extends the real numbers with a specific element denoted known as the imaginary unit and satisfies the equation.

The argument of a complex number z, in mathematics, is the angle formed by the positive real axis and the line connecting the origin and z, represented as a point in the complex plane.

Given that the complex number is z=√2/2 - √2/2i. The argument of the complex number is calculated as,

θ = tan⁻¹ ( b / a)

θ = tan⁻¹ ( √2/2 / √2/2)

θ = tan⁻¹ (1)

θ = 45°

θ = π / 4

I think C

Step-by-step explanation:

but the abcd in the graph are fhgj?

Volume of wood block :

V = (n+5)(n+8)(n+14)

Number of cubes = Volume of wood block/ Volume of small cubes

Number of cubes, N = (n+5)(n+8)(n+14)    ....1)

Number of cubes with on sides painted is :

n = (n+5-2)(n+8-2)(n+14-2)

n = (n+3)(n+6)(n+12)

It is given that :

n = N/2

(n+3)(n+6)(n+12) = (n+5)(n+8)(n+14)/2

Solving above equation, we get :

n = 2

Putting value of n in equation 1, we get :

N = (2+5)(2+8)(2+14)

N = 7×10×16

N = 1120  cubes

Therefore, number of cubes are 1120.

Hence, this is the required solution.

Answer:

.9 pounds

Step-by-step explanation:

1.37x2=2.74 (2 basketballs)

5.44-2.74=2.7

2.7 divided by 3 (footballs)=0.9

The weight of the football can be determined, given that, the weight of the

balls combined and the weight of each basketball are given.

The equation and solution that can be used to determine the weight of

each football f is; 3·f + 2.74 = 5.44

Reasons:

Given:

Number of footballs = 3

Number of basketballs = 2

The total weight of the balls = 5.44 lb.

Weight of each basketball,  = 1.37

Required:

The equation and solution that can be used to determine f

Solution:

The weight of each football, f, can be determined as follows;

The weight of the two basketballs = 2 × 1.37 = 2.74

The weight of the three footballs = 3 × f = 3·f

Weight of the three footballs + Weight of the two basketballs = 5.44

Therefore, the equation to find f, is presented as follows;

3·f + 2.74 = 5.44

Which gives;

Therefore;

The option that gives the weight of the football is; 3·f + 2.74 = 5.44; f = 0.9.

If we take 10:12 because they are similar sides, we get 10/12, or 5/6

If we take 15:18 because they are similar sides, we get 15/18, or 5/6

We know they are similar because they have the same ratio for both sides, 5/6, and have the same number as an angle.

Step-by-step explanation:

Distribute –4 to get –8x + 4 > 5 – 3x.

We can actually deduce here that the correct first step in solving the inequality –4(2x – 1) > 5 – 3x is: A. Distribute –4 to get –8x + 4 > 5 – 3x.

An inequality refers to the relationship that exist between two expressions that shows that they are not equal to each other. The signs used in an inequality are:

We see here that the first step is to use -4 to multiply the digits in the bracket. If that happens, we will have: –8x + 4 > 5 – 3x.

Then solving the inequality:

-8x + 3x > 5 - 4

-5x > 1

x < -1/5

Thus, we see that option B: Distribute –4 to get –8x + 4 > 5 – 3x. is the correct answer.
