Which of the following equations is written in standard form?
1 answer:
Standard Form is ax + by = c, where a, b, and c are not fractions and a is not negative.
So, you can go through each of your options to see which ones work with those rules.
A. 2.5x + 3y = 12 No, this is not in Standard Form. 2.5 can be rewritten as 2<span>
, menaing A is a fraction, which you can't have.
B. -10x - 3y = 1 No, this is not in Standard Form. A is -10, but A can't be negative.
C. 2x + 3y = 12 Yes, this is in Standard Form. It follows all of the rules.
D. 5x + 5y = 10 Yes, this is in Standard Form. It follows all of the rules.
So, C and D are both written in Standard Form.

Answer:
Option C) 4 congruent sides
Step-by-step explanation:
From the construction done as per statements given in the question.
AB is a common radius of circles A and circle B.
Since AB = AC = AD ( radii of circle A)
And AB = BC = BD (radii of circle B)
Therefore, AB = AC = AD = BD = BC
All sides of quadrilateral ABCD are equal.
Option C is the answer.
