Answer:
- 8x = - 32
Step-by-step explanation:
Given
1 + 2x + 1 = 10, that is
2 + 2x = 10 ( subtract 2 from both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Then
- 8x = - 8 × 4 = - 32
4/5. To divide fractions, you multiply by the reciprocal (flip the second fraction). This gives us (-3/5) x (4/-3). Since there is a -3 on the top and the bottom, they cancel out. That leaves 4/5.
coordinate of B= (2+3,0) = (5,0)
by pythagoras' theorem,
height of triangle^2 + half length of AB^2 = AC^2
height of triangle^2 = 3^2-1.5^2
height of triangle ^2= 6.75
height of triangle= √6.75
coordinates of C= (1.5,√6.75)
nothing can further be done with this?
