Answer:
B: 39 degrees
Step-by-step explanation: The angles in a triangle add up to 180 degrees. 180 - 30 - 24 = 126.
126 = (3x-9).
126 - 9 = 117.
117 / 3 = 39
Answer:
slope m = 0
Step-by-step explanation:
To find the slope for two points, you need use
m = (y2 - y1)/(x2-x1)
for point 1 (-1, -4) and point 2 (-2, -4)
m = (-4 - (-4)) / ((-2)-(-1))
m = 0 / -1
when the top number is zero, the answer is 0
if you plot the points in a graph, it is a horizontal line or y = mx + b = 0m -4
y = -4

Answer:
Scale factor = 2 for C
Scale factor = 2 for D
Scale factor = 2 for B
Step-by-step explanation:
Shape C has the dimensions of 2 x 6
Shape A has the dimensions of 1 x 3
Shape C is exactly 2 times an englargement of A because:
multiply 1 (dimension of A) times 2 (scale factors) = 2 (dimension of C)
multiply 3 (dimension of A) times 2 (scale factors) = 6 (dimension of C)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Shape D has the dimensions of 2 x 6
Shape A has the demensions of 1 x 3
Shape D is exactly 2 times an englargement of A because (same as C):
multiply 1 (dimension of A) times 2 (scale factors) = 2 (dimension of D)
multiply 3 (dimension of A) times 2 (scale factors) = 6 (dimension of D)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Shape B has the dimensions of 3 x 9
Shape A has the demensions of 1 x 3
Shape B is exactly 3 times an englargement of A because:
multiply 1 (dimension of A) times 3 (scale factors) = 3 (dimension of B)
multiply 3 (dimension of A) times 3 (scale factors) = 9 (dimension of B)
Having a root, is the same as having an exponent of 1/2
√a³, becomes a^3/2
a^(3/2) - b^3 is your answer
hope this helps
