Answer:
see explanation
Step-by-step explanation:
A difference of two squares is factored as
a² - b² = (a - b)(a + b)
(g)
1 - 81y²
= 1² - (9y)²
= (1 - 9y)(1 + 9y)
(j)
64x² - 25y²
= (8x)² - (5y)²
= (8x - 5y)(8x + 5y)
You would multiply the power by the powers of both exponents
2 × 3 = 6 so a^6
3 × 4 = 12 so b^12
Answer is
a^6b^12
Answer:
b
Step-by-step explanation:
The median of a triangle is a line that from the vertex touches the middle lets eliminate options
a=ab starts at a vertex but doensn't touch a the middle of a line X
b=cd starts at a vertex and touches the middle of a line Ye
C= ce stars at a vertex but doesn't end at the middle of a line X
d=mb starts in the middle of the triangle and and ends a vertex X
<u>SO THE CORRECT ANSWER IS B</u>

3r-6=-21
3r-6+6=-21+6 (Add 6 to both sides...)
3r=-15
r=-5
3r-6=21
3r-6+6=21+6 (Add 6 to both sides...)
3r=27
r=9
r=-5 or r=9
