Your dog is 8 years younger than your friend. In 2 years, your friend will be three times as old as your dog. How old is your do

ra1l [238]

Answer:

Dog is 2 years old

Step-by-step explanation:

Let dog's age = d

Let friend's age = f

Your dog is 8 years younger than your friend:

d +8 = f

In 2 years, your friend will be three times as old as your dog:

3(d+2) = (f+2)

3d+6 = f+2

3d = f - 4

(sub in f=d+8 from above)

3d = f - 4

3d = d+8 - 4

2d = 4

d = 2

ADHE - ADGF below. Find the value of 'x'. X H н E 8 2. 12

Vlad1618 [11]

Given:

$\Delta DHE\sim \Delta DGF$

To find:

The value of x.

Solution:

We know that, corresponding sides of similar triangles are proportional.

Since, $\Delta DHE\sim \Delta DGF$ , therefore

$\dfrac{HE}{GF}=\dfrac{DE}{DF}$

On substituting the values from the figure, we get

$\dfrac{8}{12}=\dfrac{x}{x+2}$

$\dfrac{2}{3}=\dfrac{x}{x+2}$

On cross multiplication, we get

$2(x+2)=3x$

$2x+4=3x$

$4=3x-2x$

$4=x$

Therefore, the value of x is 4.

What are the possible lengths for x, the third side of a triangle, if two sides are 21 and 10

SashulF [63]

To solve we need to use Pythagoras theorem ( $a^{2} + b^{2} = c^{2}$ )

There are 2 possible lengths for x: hypotenuse or one of the 2 shorter sides.

Hypotenuse:
10^{2} + 21^2 = $x^{2}$
100+441= $x^{2}$
$\sqrt{541} = \sqrt{ x^{2} }$
23.3≈x

Shorter leg:
$10^2 + x^2=21^2$
$x^2= 21^2-10^2$
$x^{2}$ = 441-100
$\sqrt{ x^{2} } = \sqrt{341}$
x≈18.47

What is the line of symmetry for the parabola whose equation is y = 3x2 + 24x - 1?

meriva

Hello :
y = 3x2 + 24x - 1
= 3(x²+8x) -1
= 3 (x² +2(4)(x) +4²- 4² ) -1
= 3((x+4)² -16)-1
y = 3(x+4)² - 49
the line of symmetry is : x= - 4
