Answer:
22
Step-by-step explanation:
22 x 2 is 44 plus 100 is 144
X + y = 40.....multiply by -4
4x + 6y = 180
-------------------
-4x - 4y = -160 (result of multiplying by -4)
4x + 6y = 180
------------------add
2y = 20
y = 20/2
y = 10 <===
x = 30
Answer:
The answer is option D.
Step-by-step explanation:
(4a - b)(2a - 3b)
Expand the terms
We have

Which is
8a² - 14ab + 3b²
That's option D.
