X2+20x+100 <br><br> it wouldnt hurt if you factor this one ethier hehe..
tia_tia [17]

Answer: (x+10) to the seccond power

Step-by-step explanation: 1

Use the sum-product pattern

x^{2}+{\color{#c92786}{20x}}+100

x^{2}+{\color{#c92786}{10x}}+{\color{#c92786}{10x}}+100

2

Common factor from the two pairs

x^{2}+10x+10x+100

x(x+10)+10(x+10)

3

Rewrite in factored form

x(x+10)+10(x+10)

(x+10)(x+10)

Find the area of the figure to the nearest square unit.
alex41 [277]

Answer:

357 mi²

Step-by-step explanation:

The shape is made of a triangle and a half-square

we will calculate the area of each one

  • The half square:

let A1 be the area of the half-circle:

A1= (10²*π)/2 = 50π mi²

  • The rectangle:

Let A2 be the area of the triangle:

A2= 10*20=200 mi²

  • The whole shape:

let At be the total area:

At =A1+A2= 200+50π =357.07≈ 357 mi²

Find the distance between the two points rounding to the nearest tenth (if necessary).
mote1985 [20]

<u>Understanding:</u>

This can be easily solved by using the distance formula which is

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

d: distance

(x_{1},y_{1}): coordinates of the first point, in our case it is (1,-5)

(x_{2},y_{2}): coordinates of the second point, (4,-1)

<u>Solution:</u>

<u></u>d=\sqrt{[(4)-(1)]^{2}+[(-1)-(-5)]^2}\\=\sqrt{(3)^2+(4)^2}\\=  \sqrt{9+16} \\=\sqrt{25}\\= 5<u></u>

The distance between the two points is 5.

I will mark you the brainiest for the correct answer, please be correct, Have a good day and take care, thanks. ( VIEW THE IMAGE
Gwar [14]
First error is that the legs are a and b so a should be x and b is 6 and c is 10 the second error is at the end they did not take the square root to get x by itself the real answer should be
X^2 +6^2=10^2
X^2+36=100
X^2 =64
X=8
