Answer:
B. (b+3c)+(b+3c)
C. 2(b)+2(3c)
Step-by-step explanation:
we have
Distribute the number 2
Verify each case
case A) 3(b+2c)
distribute the number 3
therefore
Choice A is not equivalent to the given expression
case B) (b+3c)+(b+3c)
Combine like terms
therefore
Choice B is equivalent to the given expression
case C) 2(b)+2(3c)
Multiply both terns by 2
therefore
Choice C is equivalent to the given expression
40 students on each bus. 248 minus 8 equals 240. 240 divides by 6 equals 40.

In 180 degree rotation, magnitude remains same, and sign of the coordinate changes. So, the coordinates of Pre-image would be: Z (-9, -2)
In short, Your Answer would be: Option B
Hope this helps!
Answer:
X° + 2x° + 45° = 180°
X = 45°, 2x = 90°
Step-by-step explanation:
Since the angles in a triangle sums up to 180
And the angles in this particular triangle is measured as 2x° + x° + 45° = 180
With this equation, we can find the value of x and 2x
2x + x + 45 = 180
3x + 45 = 180
3x = 180 - 45
3x = 135
Now divide both sides by 3
3x/3 = 135/3
X = 45
Therefore, the angles of that triangle are x° = 45, 2x°= 45 × 2 = 90° and the third angle which was given to us as 45°
