Answer:
3(x)-3(9)
Step-by-step explanation:
The brackets means you times everything within the brackets with everything outside it. So it would be 3 times x take away 3 times 9
Answer: Side QR
Step-by-step explanation: The sum of a triangle internal angles is 180°. So to determine the angles, we calculate x:
5x - 27 +4x - 7 + 3x + 10 = 180
12x = 204
x = 17
With x, solve for the angles:
m∠P = 5(17) - 27 = 58
m∠Q = 4(17) - 7 = 61
m∠R = 3(17) + 10 = 61
The relationship between angles and sides in any triangle:
- the largest angle is opposite the largest side;
- the middle angle is opposite to the middle-sized side;
- the shortest angle and side are opposite to each other;
So, the shortest side of PQR is the side opposite to the shortest angle.
The shortest angle is m∠P = 58°. Therefore, the shortest side is QR
Answer:
x = -4
Step-by-step explanation:
x= 3 is a parallel to y axis. So a parallel line to x = 3 must be parallel to y axis.
A line parallel to y axis has a generic equation: x = h. We know that the line passes to the point with has x coordinate = -4
So the equation is x= -4
Answer:
