Answer:

30 Ways

Step-by-step explanation:

The word SEEDS has 5 letters.

There are 3 different (distinguishable) letters. Respectively there are two identical letters S and two identical letters E.

Following to the logic of the n 2), we must divide 120 (the total number of formal permutations of 5 symbols) by (2*2) = 4.

As a result, the final formula for the number of arrangements in this case is represented below;

$5! / 2 * 2 =\\120 / 4 =\\30\\\\Solution = 30 Ways$

Answer:

$(3a-y)(3a+y)$

Step-by-step explanation:

This is a difference of squares that has the form and factors to:

$a^2x^2-b^2 = (ax-b)(ax+b)$

Here take the square root of each term for the factors.

$9a^2-y^2 = (3a-y)(3a+y)$

Marta has gone for a walk and has covered three quarters of the total route so far. If she still has 2 kilometres to walk, how l

aleksklad [387]

Answer:

The total route is 8 kilometers.

Step-by-step explanation:

Let the distance of the total route be x

Marta has gone for a walk and has covered three quarters of the total route so far. This means that she has covered a distance of

3/4 × x = 3x/4 kilometers

she still has 2 kilometres to walk. This means that the total route or distance = the sum of the distance that she covered already and the distance she has remaining. Therefore,

x = 3x/4 + 2

x - 3x/4 = 2

(4x - 3x) / 4 = 2

Cross multiplying

4x - 3x = 4 × 2

x = 8

The total route is 8 kilometers.

Solve for x in the equation x^2 + 2x+ 1 = 17.

muminat

Answer:

first, subtract 17 on both sides: x²+2x-16=0

this cannot be factored, so use the quadratic formula to solve for x:

b²-4ac=2²-4(10(-16)=4+64=68

√68=2√17

so x=(-2+2√17)/2 or x=(-2-2√17)/2

x=-1+√17 or x=-1-√17
