I'm guessing d b are equal and a and c are equal or I don't think we would be able to solve so going on that
if angle d is 57 angle b must also be 57
A parallelegram has angles that add up to 360
So 360= 57+57+2c
Solve
360=114+2c
-114 both sides
246=2c
÷2 both sides
123=c
Hi there!
Since the yellow marbles to the radio of total marbles is 3/15,
3/15 = 5
We need to divide the total amount is times the marble is drawn by the ratio.
20 ÷ 5 = 4
So, the yellow marble would be drawn 4 times.
Hope this helps!
Answer:

Step-by-step explanation:

utilise the Foil method to expand brackets:
F - mulply the first terms (x and x)
O - multiply the outside terms ( x and -2)
I - multiply the inside terms (5 and x)
L - multiply the last terms (5 and -2)
Then add them as following:

Then combine like terms:
