Hello,
Let's calculate the radius:
r²=5²+7²=74
The circle's equation is (x+5)²+(y+7)²=74
Answer C
Answer:
4
Step-by-step explanation:
You need to try out all the numbers.
lets start with 4
if there where 4 red marbles then there would be 9 times as many marbles
so 4 x 9 = 36
Now we add and see if the sum is 40
36 + 4 = 40
We got it on the first try
You can use the same method on more problems like these.
Hope this helps :)
Answer:
Step-by-step explanation:
total =20
red=10
P(red)=10/20=1/2
Given the following expression:
To simplify the expression, we will use the following rules:
