Answer:
B
Step-by-step explanation:
25y² - 16 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
Given
25y² - 16
= (5y)² - 4²
= (5y - 4)(5y + 4) → B
Answer:
b. (2,0)
Step-by-step explanation:
To find which ordered pair is a solution, we have to replace then into the equation, and the result has to be an identity, that is, 0 = 0.
Equation:
Option a:
, so 
Not an identity, so this ordered pair is not a solution.
Option b:
, so 
Identity, and thus, the correct answer is given by option b.
From the figure, we already have
RT = UT
and
TK = TK
Since these are already conditions for two sides being congruent, we only need an included angle to be congruent. So, the missing information is
∠RTK <span>≅ </span>∠<span>UTK</span><span />
Use the order of operations: PEMDAS (parenthesis, exponents, multiplication, division, addition, & subtraction.)
Hope this helps!
Try this:
this sequence can be created using the following algorithm:
6+5=11
11-6=5+5=10 (+5 and -6)
Finally: 6 11 5 10.
