Answer:
x = 9
Step-by-step explanation:
You have to use the Secant Segment theorem:
AB * AC = AD * AE
This means that the external piece of the secant times the whole secant for one is equal to the external piece of the secant times the whole secant for the other.
Now, setup an equation:
8(x + 8) = 4(30 + 4)
Simplify:
8x + 64 = 120 + 16
8x = 72
x = 9
Answer:
4/15
Step-by-step explanation:
7/15 - 3/15 = 4/15

Step-by-step explanation:
Answer:
The coordinates of the image are (3,1)
Step-by-step explanation:
Here, we want to get the coordinates of the image given the pre-image coordinates and the scale factor
What we shall do here is to multiply the scale factor by each it the coordinates since it is centered at the origin
The coordinates of the image is thus;
(1/4 * 12, 1/4 * 4)
= (3,1)
Step-by-step explanation:
AB=BC
8x+6=6x+18
2x=12
x=6
so
AB= 48+6=54cm
BC=36+18=54cm
AD=CD
8y+20=12y-8
-4y=-28
y=7
so
AD= 84-8=76cm
CD=56+20=76cm
AE=2x+4y
AE=2×6+4×7
AE=40cm
AC=2×40=80cm
