Math expressions that equal 13​

Mathematics
1 answer:
qaws [65]3 years ago
7 0

Step-by-step explanation:

There can be a lot of math expressions that may equal 13. Here are some of the expressions that equal 13​.

  • 9 + 4 = 13
  • 15 - 2 = 13
  • 1 × 13 = 13

Now, let us consider some interesting expression

x^3-x^2+x+7

If the value of x = 2, then the expression will be equal to 13.

i.e.

2^3-2^2+2+7=13        ∵ when x = 2

Considering a word problem

<em>'Tom has 10 oranges while Tony has 3 more oranges than Tom. How many oranges Tony has?</em>

Let 'x' be the number of oranges Tom has.

The number of oranges Tony has = x + 3

as Tom has 10 oranges, so x = 10

Therefore, the number of oranges Tony has = x + 3

                                                                          = 10 + 3 = 13

Therefore, the number of oranges Tony has = 13

Let P=x^2+6<br> PLEASE SHOW WORK!!<br> 15 POINTS
stellarik [79]

Answer:

Step-by-step explanation:

P = x^2 + 6

(x^2+6)^2 - 21 = 4x^2 + 24\\(x^2+6)^2 - 4x^2 - 45 = 0

Solving for 4x^2:

P = x^2 +6

P - 6 = x^2

4(P - 6) = 4x^2

Substitution:

p^2 - 4p - 24 - 45 = 0\\p^2 -4p - 69 = 0
