First fine the dialation divide 6 by 4 you get 1.5 so the dialation of these shapes is 1.5 now you just simply find the measurments.... 9 divided by 1.5 is 6 so BC is 6. now 7*1.5 is 10.5 so QR is 10.5 now the angles never change in a dialation so <P= 86*.
Hope this helped you!!! have an amazing day!

All you do is find the scale factor and go from there so
AB and side QP are similar so the scale factor is 1.5
In order to find QR just multiply 7*1.5=10.5
Then to find BC you just do just multiply it by 2/3*9=6
The angle is 86 degrees

Plz don’t be rude if i got brainly i’m gonna use it

SSSSS [86.1K]

Answer:

y=-5x-36

Step-by-step explanation:

-66-(-61)= -5

6-5= 1

-5/1= -5

Y=-5x + B

-66= -5(6) + B

-66= -30 + B

-66 + 30 = (-30 +30) + B

-36 = B

Y= -5x-36

The lenght of the library is 13 inches.The lenght of the actual library is 78 feet. Which scale leon use to create the scale dra

Allisa [31]

So the scale used was

1 inch = 6 feet

Step-by-step explanation:

Given

Length of library on drawing = 13 inches

Actual length of library = 78 feet

In order to find the scale we divide the actual length by the length of library on drawing.

So,

Scale = $Scale = \frac{Actual\ length}{Length\ on\ drawing}\\=\frac{78}{13}\\=6$

So the scale used was

1 inch = 6 feet

Factor 2a2b3 - 14ab + 16a

zhuklara [117]

Answer:

2a(b^3 - 7b + 8)

Step-by-step explanation:

I'm assuming that 2a2b3 is 2a2b^2. If not, this answer isn't correct.

Look at the whole numbers. Is there a number that divides into them evenly? Yes, 2, so you pull 2 from the problem and divide each number by 2. Do the same for each variable.

2a2b3 - 14ab + 16a

2(ab^3 - 7ab +8a)

2a(b^3 - 7b + 8)
