Answer:
BC = 144 units
Step-by-step explanation:
BC = BD + DC , substitute values
8x = 4x + 10 + 3x + 8 = 7x + 18 ( subtract 7x from both sides )
x = 18
Thus
BC = 8x = 8 × 18 = 144 units
Answer:
90 cm²

Hey there, 100/5=20, 20/4=5. 4*5=20, 20*5=100. Now, 4*5*5=100. Therefore, the number that goes in the box to make the number sentence true is 5.
