Answer:
BC is 25 units
Step-by-step explanation:
AB = AC
4x + 4 = 6x - 14
4x + 4 - 4x + 14 = 6x - 14 - 4x + 14
18 / 2 = 2x / 2
9 = x
2(9) + 7
18 + 7
25
Answer: BC is 25 units
Answer:
8xy-3y + 2(9x-5y+4) = 18
Step-by-step explanation:
We need to find the value of the given expression:
8xy-3y + 2(9x-5y+4) ....(1)
when x = 3 and y = -4
Put the values of a and y in equation (1)
8×3×(-4)-3(-4)+ 2(9×3-5(-4)+4)
= -96 +12 + 2(27 + 20 +4)
= -84 + 2(51)
= -84 + 102
= 18
Hence, the value of the given expression is 18.
