Answer:
When simplifying using addition and subtraction, you combine “like terms” by keeping the "like term" and adding ... Solve the following equations for x: 1) x + 5 = 12. 2) x – 11 = 19. 3). 22 – x = 17 ... To get the x by itself, you will need to get rid of the 5 and the 3. ... We check the answer by putting it back in the original equation:.
Step-by-step explanation:
Answer: x=20 degrees
Step-by-step explanation:
A triangle has 120 degrees in total. If you add all the givin angles then you will get 80. 120-80=40. Those 2 blank sides are the same length. So you divide 40 by the 2 angles. 40/2=20
$23.40
Since we know how much Olivia spent total, and we know how much she spent on the sunglasses, we just subtract 16.35 from 39.74, and the final answer is 23.40
Another name for CD would be DC it’s the same size and line just backwards
( 3 m - 2 n ) · ( 4 m - n ) =
= 12 m² - 3 m n - 8 m n + 2 n² = 12 m² - 11 m n + 2 n²
Answer:
The polynomial is:
12 m² - 11 m n + 2 n².
