Can somebody help me with this question?

Bas_tet [7]

Answer:

86 yd

Step-by-step explanation:

the area of the shaded region is 2924 yd²

let b the doted side next y :

the area of the total triangle is :

A = (y+b)*68/2 = 2924+ b*68/2

$\frac{(y+b)*68}{2}$ = $\frac{b*68}{2}$ + 2924
$\frac{68*(y+b-b)}{2}$ = 2924
68*y/2 = 2924
68y = 2*2924
y= (2*2924)/68
y= 86 yd

What is the image of (-8,-8)(−8,−8) after a dilation by a scale factor of \frac{1}{4} 4 1 centered at the origin?

anastassius [24]

We conclude that the image of (-8, -8), after a dilation by a scale factor of 1/4, is (-2, -2).

<h3>What is the image after the dilation?</h3>

For a point (x, y), a dilation by a scale factor of k gives the point (k*x, k*y).

Now, in this case, we have the point (-8, -8) and the scale factor is k = 1/4.

Then, using the above relation, we can write the coordinates of the image after the dilation as:

(-8*(1/4), -8*(1/4)) = (-2, -2).

We conclude that the image of (-8, -8), after a dilation by a scale factor of 1/4, is (-2, -2).
