Answer:
vertical angles and complementary
400 is another way to right 4 hundreds
We can Notice that ∠ABC = ∠ACB
We know that if Two Angles are Equal then Angles Corresponding to those Sides are also Equal.
⇒ AB = AC
⇒ 4x + 4 = 6x - 14
⇒ 6x - 4x = 4 + 14
⇒ 2x = 18
⇒ x = 9
⇒ Length of BC = 2x + 7 = 2(9) + 7 = 18 + 7 = 25 units
Answer:

Step-by-step explanation:
subtract by 5 on both sides. ur left with

square root b and 16. the square root cancels out b squared. find the square root of 16. the square root of 16 is 4
I am pretty sure that addiction because if you add 198 6 times it woyuld be the same as multiplyaction
