It would be n + ( 8 + 6 ) because n is separated from the addition of 8 and 6 as asked in the question.

Answer:

n + (8+6)

Step-by-step explanation:

"The sum of n and the sum of 8 and 6" is telling us that we are going to sum up the numbers 8 and 6  (this would be 8 + 6) and then we are going to add n

So the correct answer would be n + (8+6)

1. (n + 6)8 is incorrect because this expression tells us that we are going to sum n plus six and then we are going to multiply the result by 8.

2. n (8 + 6) is incorrect because this expression tells us that we are going to sum 8 + 6 and then we are going to multiply the result by a number n.

Therefore the correct answer is n + (8 + 6)

Ken jumps 1 1/5 metres steve jumps 1.5 metres steve jumps further than ken how much further does steve jump than Ken?
monitta

Answer:0.3 m

Step-by-step explanation:

Given

Ken can Jump 1\ \frac{1}{5}\ m

Steve can Jump 1.5\ m

Converting mixed fraction into a fraction

\Rightarrow 1\ \dfrac{1}{5}=\dfrac{1\times 5+1}{5}\\\\\Rightarrow \dfrac{6}{5}\ m=1.2\ m

The difference between their Jumps is

\Rightarrow 1.5-1.2=0.3\ m

Steve Jumps 0.3 m more than ken

Simplify the following fraction: <img src="https://tex.z-dn.net/?f=%5Cfrac%7B4-25x%5E2%7D%7B10x%5E2-11x-6%7D" id="TexFormula1" t
Alexeev081 [22]

Answer:

\frac{(2+5x)(2-5x)}{2x(5x-6)}

Step-by-step explanation:

Simplify the numerator:

Rewrite 4 as 2^{2}

\frac{2^{2}-25x^{2}  }{10x^{2}-11x-x }

Rewrite 25^{2} as (5x)^{2}

\frac{2^{2}-(5x)^{2}  }{10x^{2} -11x-x}

Since both terms are perfect squares, factor using the difference of squares formula, a^{2} -b^{2} =(a+b)(a-b) and b = 5x.

\frac{(2+5x)(2-(5x))}{10x^{2}-11x-x }

Multiply 5 by -1.

\frac{(2+5x)(2-5x)}{10x^{2}-11x-x }

Simplify the denominator:

Subtract x from -11x

\frac{(2+5x)(2-5x)}{10x^{2}-12x }

Factor 2x out of 10x^{2} -12x

\frac{(2+5x)(2-5x)}{2x(5x-6)}
