You have to move the decimal
42n, you can't take the "n" away. The "n" means times a number, so I I write n=2, then the expression will be 42 x 2, substitute the n with a 2
Answer:
1.891
X
Step-by-step explanation:
Answer:
B) 120 degrees
Step-by-step explanation:
The two triangles are the same, so first find the measure of angle B.
To do this first solve for angles A and C. Solve for A first: 4x or 4(5), which is 20 degrees. Now solve for C: 8x or 8(5), which is 40 degrees. Add 40 + 20 degrees to get 60 degrees total of those two angles.
A triangle has 180 total degrees, so to solve for the measure of Angle B, subtract 180 - 60 to get 120 degrees.
Since the two triangles are the same, Angle D is the measure as Angle B.
Hope it helps!

Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
11
5x - y + 6 = 0 ( subtract 6 from both sides )
5x - y = - 6 ← in standard form
12
y + 1 = 2(x - 3) ← distribute parenthesis
y + 1 = 2x - 6 ( subtract y from both sides )
1 = 2x - y - 6 ( add 6 to both sides )
7 = 2x - y, thus
2x - y = 7 ← in standard form
