Answer:
AC= 20
Step-by-step explanation:
since the two figures are similar, CB Is congruent to FD
since image/preimage, 12/3 =4
The dilation is 4.
AC is congruent to EF
EF=5
4 x 5 = 20
AC=20
someone correct me if im wrong :)
Step-by-step explanation:
Total marbles = 9 + 4 + 3 + 2 = 18
Probability of both red marbles = 3 / 18 = 1/6
We need to evaluate the value of fraction
.
We also given j=12.
In order to evaluate the value of fraction
, we need to plug j=12.
Plugging j=12, we get
![\frac{j}{4}= \frac{12}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bj%7D%7B4%7D%3D%20%5Cfrac%7B12%7D%7B4%7D)
We have 12 in numerator and 4 in denominator.
We always divide top number by bottom number.
So, we need to divide 12 by 4.
On dividing 12 by 4 we get 3.
<h3>Therefore,
![\frac{j}{4} = 3.](https://tex.z-dn.net/?f=%5Cfrac%7Bj%7D%7B4%7D%20%3D%203.)
