Can you take a picture of the problem?
Answer: a 68 c57 b55 I think
Step-by-step explanation:
A triangles angles add up too 180 so just subtract the sum and the two angles and you are done.
Answer:
The formula for the area of a square with sides of length x is A = x2 so
x2 = 400 is the equation
This equation has 2 solutions, namely x = ±√400 = +20 or -20
The negative solution does not make sense because a length cannot be less than 0.
The total length needed to go around the painting is the perimeter of the square, which is
P = 4*x = 4*20 = 80 inches
Answer:
D
Step-by-step explanation:
If you think of the x-axis as your horizontal line, you can see that there is more than one value for x for y=0.
For instance, (-2,0), (0,0), (0,2).
22.10 X 0.15 = 3.315
22.10+3.315= 25.415
= $25.42
