Answer:
B) (4x-5i)(4x+5i)
Step-by-step explanation:
The expression can be treated as the difference of squares, and factored accordingly. That factoring is ...
a² -b² = (a -b)(a +b)
__
Here, we have ...
a² -b² = 16x² -(-25)
a² = 16x² ⇒ a = 4x
b² = -25 ⇒ b = √-25 = 5i
Then the factoring is ...
(a -b)(a +b) = (4x -5i)(4x +5i)
Answer:
The Answer is 12
x
^4
y
^3
Step-by-step explanation:
Answer:
3(2x-5y) = 3(-1)
2(-3x+2y)= 2(7)
6x-15y = -3
-6x +4y = 14
now, add the two equations
0x - 11y = 11
divide both sides by -11
y = -1
insert -1 in for y in either original equation and solve for x.
2x -5(-1) = -1
2x +5 = -1
2x +5 -5 = -1 -5
2x = -6
2x ÷2 = -6 ÷2
x= -3
