Answer:
50
Step-by-step explanation:
Answer:
See below
Step-by-step explanation:
x(x-2y)-(y-x)2
Final result :
-y2
Step by step solution :
Step 1 :
Equation at the end of step 1 :
x • (x - 2y) - (y - x)2
Step 2 :
2.1 Evaluate : (y-x)2 = y2-2xy+x2
Final result :
-y2
Answer:
A
Step-by-step explanation:
Given
x² - 16x + 64 = 0 ← left side is a perfect square and factors as
(x - 8)² = 0, thus
x - 8 = 0 ⇒ x = 8 with multiplicity 2
Thus x = 8 is the only solution → A
Bc = 24
Ad = 5y-1
5 times what is 25?
5 x 5 = 25
25 - 1 = 24
Therefore Y = 5
5(5) - 1 = 24
where a=a, then b=c
