Answer:
9(p + q)(9p + 9q - 1)
Step-by-step explanation:
Given
81(p + q)² - 9p - 9q ← factor out - 9 from these 2 terms
= 81(p + q)² - 9(p + q) ← factor out 9(p + q) from each term
= 9(p + q)(9(p + q) - 1)
= 9(p + q)(9p + 9q - 1)
So this question is already perfectly set up. Since the 6 and -6 cancel you’ll be left with 5x + 3x which is 8x and -32 + 48 which is 16. 8x=16. Isolate x to get that x=2. Plug 2 back into one of the equations. 5(2) -6y = -32. Solve for y now. -10-32 equals -42. Divide -42 by -6 to get 7. So the final coordinate where the two equations will intersect is (2,7)
Answer:
C≈6.28mm
Step-by-step explanation:
C=2πr
= 2·π·1≈6.28319mm
Answer:
76 because the angles must add up to 360
Answer:
y=-3/2x+5
Step-by-step explanation:
3x+2y=10
2y=10-3x
2y=-3x+10
y=-3/2x+10/2
y=-3/2x+5
