So the question or problem ask to find the equation of a circle which has a center of (-1,2) and a radius of 3 units. To get the equation of the circle, you must first follow the formula which is (x-h)^2 +(y-k)^2 = r^2. So the answer would be letter D. (x+1)2+(y-2)2=9. I hope you are satisfied with my answer
Okay, so a meter is a measure in length. Like a foot, or an inch. To square a measure of length, four equal measures of length (such as a meter) are put together to form a square. This is used for things like construction, or home refurbishing. Ex. 'My kitchen floor is 26 square meters'
Step-by-step explanation:
180-124=56°
180-56-2x-(180-6x)=0
180-56-2x-180+6x=0
-56+4x=0
4x=56
x=14°
........
2x=28
6x=84
Answer:
The factored form of this would be (x + 4)(x + 9)
Step-by-step explanation:
In order to determine the numbers in the parenthesis, we need to find numbers that multiply to the constant (36) and add up to the middle term (13). In order to do that, we list the factors of the constant and look for those that add up to 13.
1, 36
2, 18
3, 12
4, 9
6, 6
As you can see, 4 and 9 are the only pair that satisfy the stipulations. So we place them in a parenthesis with x's and express as the following.
(x + 4)(x + 9)
