Some to do. So do it.

Answers

Answer:

1. A=42

L=14

42=W(14)

divide both sides by 14

3=W

2. A=96

L=12

96=W(12)

divide both sides by 12

8=W

3. A=90

L=18

90=W(18)

divide both sides by 18

5=W

4. A=1.50

L=15

1.50=W(15)

divide both sides by 15

0.1=W

it’s pythagorean theorem btw :)

what is the vertex of f(x)=x^2-9x+14

Answers

Its going to be a lot of steps

Step one

To complete the square, the same value needs to be added to both sides

f(x)+?=x^2 -9x+?+14

Step two

To complete the square add to the expression

x^2 -9 + 81/4= ( x- 9/2 ) ^2 add 81/4
To the expression

f(x)+?=x^2 -9+ 81/4 + 14

Step three

Since 81/4 was added to the right-hand side, also add 81/4 to the left-hand side

f(x)+81/4=x^2 -9x+81/4+14

Step four

Use a^2-2ab +b^2 = ( a-b)^2 to factor the expression

f(x)+81/4=(x-9/2)^2+14

Step five

Move the constant to the right-hand side and change its sign

f(x)=(x-9/2)^2 + 14- 81/4

Last step

Calculate the difference

F(x)=(x-9/2)^2 -25/4

That was to long

what is the perimeter of the triangle. i do not know how to start this problem. any help will be greatly appreciated :))

Answers

Given:

Point F,G,H are midpoints of the sides of the triangle CDE.

[tex]FG=9,GH=7,CD=24[/tex]

To find:

The perimeter of the triangle CDE.

Solution:

According to the triangle mid-segment theorem, the length of the mid-segment of a triangle is always half of the base of the triangle.

FG is mid-segment and DE is base. So, by using triangle mid-segment theorem, we get

[tex]\dfrac{1}{2}DE=FG[/tex]

[tex]DE=2(FG)[/tex]

[tex]DE=2(9)[/tex]

[tex]DE=18[/tex]

GH is mid-segment and CE is base. So, by using triangle mid-segment theorem, we get

[tex]\dfrac{1}{2}CE=GH[/tex]

[tex]CE=2(GH)[/tex]

[tex]CE=2(7)[/tex]

[tex]CE=14[/tex]

Now, the perimeter of the triangle CDE is:

[tex]Perimeter=CD+DE+CE[/tex]

[tex]Perimeter=24+18+14[/tex]

[tex]Perimeter=56[/tex]

Therefore, the perimeter of the triangle CDE is 56 units.
