The solution to x2 – 10x = 24 is

Answer:

x = - 2, x = 12

Step-by-step explanation:

Given

x² - 10 x  = 24 ( subtract 24 from both sides )

x² - 10x - 24 = 0 ← in standard form

To factorise the quadratic

Consider the factors of the constant term (- 24) which sum to give the coefficient of the x- term (- 10)

The factors are - 12 and + 2, since

- 12 × 2 = - 24 and - 12 + 2 = - 10, thus

(x - 12)(x + 2) = 0

Equate each factor to zero and solve for x

x - 12 = 0 ⇒ x = 12

x + 2 = 0 ⇒ x = - 2

Elena has 2 fewer hats then fran. Together, they have 14 hats. Which equation represents this situation.
Free_Kalibri [48]
<h2>Greetings!</h2>

Answer:

2x - 2 = 14

Step-by-step explanation:

Let x be the amount of hats Fran has, if Elena has -2 hats, then this can be shown by x - 2

So then

x + x - 2 = 14

2x - 2 = 14

You haven't asked this but to find the amount of hats they have, move the -2 over to the other side making it a +2:

2x = 14 + 2

2x = 16

x = 8

So Fran has 8 hats and Elena has 6 hats.

Is this sequence arithmetic,<br> geometric<br> or neither?<br> 3.5. -4, -7.5...
kvasek [131]

Answer:

Neither

Step-by-step explanation:

If the sequence was geometric, each term would be multiplied by the same multiplier to get to the next one. We can check if the multiplier is the same by taking a term and dividing it by the term before it. For example,

-4/3.5=-1.14285714

-7.5/-4=1.87500

The multiplier between the terms aren't the same so it's not geometric.

For arithmetic, the distances between each term would be the same, and we can take the same idea from the geometric sequence, but use subtraction instead of division

-4-3,5=-7.5

-7.5-(-4)=-3.5

Again, the distances aren't the same, so it's not arithmetic.

What does the E stand for in a calculator
FromTheMoon [43]
Take a single digit number with a decimal (Two digits total), times ten to the power of whatever. E is used for very large or very small numbers and helps shrink the writing down. Ex. 1E+20 is 1.0 with the decimal moved to the right twenty spaces.
