7 is your GCF
87/6-66/6
=21/6
=3 3/6
=3 1/2
=3.5
16, first you need to add on the four he lost to the 18 he ended with.
Solution: For finding QR we need to apply Pythagoras Theorem
What is Pythagoras Theorem ?
ans : Pythagoras Theorem is the sum of square of two sides which is equal to the third side or the hypotenuse. This formula is valid oy incase of Right-Angled Traingle because one of three angles here is 90°
According to this law let's apply it in the diagram shown here.
- (Hypotenuse)² = (Adjacent)² + (Opposite)²
- (5x - 2)² = (QR)² + (3x - 1)²
- (QR)² = (5x - 2)² - (3x - 1)²
After factorising both of them we get
- (QR)² = 25x² - 20x + 4 - (9x² - 6x + 1)
- (QR)² = 25x² - 20x + 4 - 9x² + 6x - 1
So, QR is √(16x² - 14x + 3)
Answer:
see below
Step-by-step explanation:
The y-coordinate measures the vertical distance relative to the x-axis on the coordinate plane. A point that is 3 units below the x-axis will have a y-coordinate of -3. The y-coordinate is listed 2nd in an (x, y) ordered pair, so you're looking for an ordered pair with -3 in the second spot.
