Step-by-step explanation:
Answer:
JUSTIFICATION↓
∠1 ≅ ∠2 <u>(∵ Vertically-opposite angles are equal)</u>
Step-by-step explanation:
Since ∠1 lies vertically opposite to ∠2 and vice -versa , therefore ∠1 and ∠2 are equal to each other
The numbers are 3.5 and -10.5
Step-by-step explanation:
- Step 1: Sum of two numbers = -7. Let one number be x. Then, the other number = -7 - x. Difference = 14
⇒ x - (-7 - x) = 14
⇒ x + 7 + x = 14
⇒ 2x = 7
∴ x = 7/2 = 3.5
-7 - x = -7 - 3.5 = -10.5
14/12 as a mixed number would be 1 2/12 hope that is what you were asking!
We can simplify this by multiplying all the terms together.
2x * x + 2x * 1 + 9 * x + 9 * 1
= 2x^2 + 2x + 9x + 9
= 2x^2 + 11x + 9
Hope this helped!
