Im not sure how to do the equation part but Sarah's dog is 20 pounds and her sisters is 40 pounds.
Answer:
x = ± √2 = ± 1.4142
Step-by-step explanation:
area = I x w
so 25 x 13 = 325 square inches
Standard form is written Ax + By = C where A, B, and C are all integers.
In other words, no fractions.
Also, the A or the coefficient of the x term must be positive.
The only thing we need to do is add 7x to both sides to get 7x + y = -1.
So 7x + y = -1 is our answer.
The correct answer would be A. There is only a 1/8th percent chance of the spinner landing on 4.
