Answer:
Your answer would be .
Step-by-step explanation:
The formula for the equation of a circle is , where (h, k) is the center of the circle, and r is the radius. Since the center is (-1, 3), the left half of the equation is . Now, all we have to do now is find the radius, r. To do that, you can use the distance formula to find the distance between the center (-1, 3) and a point that passes through the circle, or is on the circumference, (-4, -2). When you calculate that, you will get , so the radius is . But, we want the radius squared, which is 34. So, the final answer is what I wrote above.
Hope that helped! :)
Answer=2x+21 do you want the whole solution?
Let the angles be 3x,3x and 4x
so 3x+3x+4x = 180
therefore x= 18
so, angles are 54,54,72 °
so it's B !!
1 in = 2.54 cm
1 cm = 0.01m
therefore
1 in = 0.0254 m → 1 m = 39.37 in
Your answer: 2 m = 2 · 39.37 in = 78.74 in.
A more explained answer to show your teacher that you know the material and are not cheating is to multiply 350 by 2.5. this is the equivalent of 2.5 gallons, and 350x2.5 is 350x2+350x.5=700+175=875 sq feet that 2.5 gallons will cover
