Answer:

f(x+h)=x^2+2xh+h^2+2x+2h

Option D is correct option.

Step-by-step explanation:

We are given: f(x)=x^2+2x

We need to find f(x+h)

For finding f(x+h) we need to replace x by x+h

f(x+h)=(x+h)^2+2(x+h)\\We \ know \ (a+b)^2=a^2+2ab+b^2\\f(x+h)=x^2+2xh+h^2+2x+2h

Finding f(x+h) we get:

f(x+h)=x^2+2xh+h^2+2x+2h

Option D is correct option.

What percent of 38 is 15
Nostrana [21]
Let's assume x=15. 38x=100×15=1,500. \frac{38x}{38}= \frac{1,500}{38}. x=39.472 which is rounded to 39%

What is the length side of a triangle that has vertices at (-5, -1), (-5, 5), and (3, -1)?
spayn [35]

Answer: 6,8 and 10

Step-by-step explanation:

To find the length , all we need to find is the distance between each point ,

the formula for calculating distance between two points is given by :

D = \sqrt{(x_{2}-x_{1}) ^{2}+(y_{2}-y_{1}) ^{2}}

Let the points be :

A ( -5,-1)

B(-5,5)

C(3,-1)

Calculating the length AB , we have

D1 = \sqrt{(x_{2}-x_{1}) ^{2}+(y_{2}-y_{1}) ^{2}}

D1 = \sqrt{(-5+5)^{2}+(5+1)^{2}}

D1 = \sqrt{36}

D1= 6

Calculating the length AC , we have

D2 = \sqrt{(x_{2}-x_{1}) ^{2}+(y_{2}-y_{1}) ^{2}}

D2 = \sqrt{(3+5)^{2}+(-1+1)^{2}}

D2 = \sqrt{64}

D2 = 8

Calculating the length BC , we have

D3 = \sqrt{(x_{2}-x_{1}) ^{2}+(y_{2}-y_{1}) ^{2}}

D3 = \sqrt{(3+5)^{2}+(-1-5)^{2}}

D3 = \sqrt{100}

D3 = 10

Therefore ,the length of the sides of the triangle are 6,8 and 10
