The answer to the expansion of the expression, 3+5^2 is 28

<h3>How to expand an expansion</h3>

An expansion of an expression is the evaluation of the expression to its simplest form

Given:

3+5^2

= 3 + 5²

= 3 + (5 × 5)

= 3 + 25

= 28

Therefore, answer to the expansion of the expression, 3+5^2 is 28

Suppose you choose a team of two people from a group of n > 1 people, and your opponent does the same (your choices are allow

jonny [76]

Answer:

The number of possible choices of my team and the opponents team is

$\left\begin{array}{ccc}n-1\\E\\n=1\end{array}\right i^{3}$

Step-by-step explanation:

selecting the first team from n people we have $\left(\begin{array}{ccc}n\\1\\\end{array}\right) = n$ possibility and choosing second team from the rest of n-1 people we have $\left(\begin{array}{ccc}n-1\\1\\\end{array}\right) = n-1$

As { A, B} = {B , A}

Therefore, the total possibility is $\frac{n(n-1)}{2}$

Since our choices are allowed to overlap, the second team is $\frac{n(n-1)}{2}$

Possibility of choosing both teams will be

$\frac{n(n-1)}{2} * \frac{n(n-1)}{2} \\\\= [\frac{n(n-1)}{2}] ^{2}$

We now have the formula

1³ + 2³ + ........... + n³ = $[\frac{n(n+1)}{2}] ^{2}$

1³ + 2³ + ............ + (n-1)³ = $[x^{2} \frac{n(n-1)}{2}] ^{2}$

= $\left[\begin{array}{ccc}n-1\\E\\i=1\end{array}\right] = [\frac{n(n-1)}{2}]^{3}$

Please help me

galben [10]

Answer:

A = 0.25*j + 1

Step-by-step explanation:

The question presented here is an application of linear models. The $1 amount is fixed and does not depend on any factor such as the cups of orange juice sold.

Furthermore, we are informed that we earn $0.25 for every cup of orange juice sold. This means that we shall earn 0.25 j by selling j cups of orange juice.

The variable total amount, A will thus depend on the fixed amount of $1 and the variable income 0.25 j.

The equation in two variables that will represent the total amount A (in dollars) you have after selling j cups of orange juice will thus be;

A = 0.25*j + 1

HELP Select the correct answer.<br> What is the solution of this linear system?

deff fn [24]

The solution for the given linear equation is ( 14, 8, 10 ), that is mentioned in option C.

Step-by-step explanation:

The give linear equations,

$p+q+r = 32$ ............................(1)

$p-r = 4$ .............................(2)

$2p+q=36$ ............................(3)

Step:1

Check for Option A,

A ( 16, 8, 8 ) - ( p, q, r )

Equation (1) becomes,

16 + 8 + 8 = 32

32 = 32

Equation (2) becomes.

16 - 8 = 4

8 ≠ 4

Equation (3) becomes,

2(16) + 8 = 36

40 ≠ 36

Check for Option B,

B ( 14, 10, 8 ) - ( p, q, r )

Equation (1) becomes,

14 + 10 + 8 = 32

32 = 32

Equation (2) becomes.

14 - 8 = 4

6 ≠ 4

Equation (3) becomes,

2(14) + 10 = 36

38 ≠ 36

Check for Option C,

C ( 14, 8, 10 ) - ( p, q, r )

Equation (1) becomes,

14 + 8 + 10 = 32

32 = 32

Equation (2) becomes.

14 - 10 = 4

4 = 4

Equation (3) becomes,

2(14) + 8 = 36

36 = 36

Check for Option D,

D ( 10, 12, 10 ) - ( p, q, r )

Equation (1) becomes,

10 + 12 + 10 = 32

32 = 32

Equation (2) becomes.

10 - 10 = 4

0 ≠ 4

Equation (3) becomes,

2(10) + 12 = 36

32 = 36

Check for Option E,

E ( 10, 15, 10 ) - ( p, q, r )

Equation (1) becomes,

10 + 15 + 10 = 32

35 ≠ 32

Equation (2) becomes.

10 - 10 = 4

0 ≠ 4

Equation (3) becomes,

2(10) + 15 = 36

35 ≠ 36

Result:

The solution for the given linear equation is ( 14, 8, 10 ), that is mentioned in option C.
