First lets simplify the equation by removing the parenthesis 

m + n + 3 + m + n + 4

Gather the like terms

(m + m) + (n + n) + (3 + 4)


Now simplify it add 3 + 4 so it can be 7


Answer: C) 2m + 2n + 7 or the third option.

Q is the midpoint of line segment PR. PR=9x-31 and QR=43 ; find x
bulgar [2K]

notice that, if Q is the midpoint of PR, that simply means that PQ = QR = 43.


\bf \boxed{P}\underset{\leftarrow 9x-31 \to }{\stackrel{\stackrel{\downarrow }{43}}{\rule[0.35em]{10em}{0.25pt}}Q\stackrel{43}{\rule[0.35em]{10em}{0.25pt}}}\boxed{R}
\\\\\\
9x-31=43+43\implies 9x-31=86\implies 9x=117
\\\\\\
x=\cfrac{117}{9}\implies x=13

If m∠9 ≅ 95°, find m∠14. answers: Question 5 options: 85° 95° 90° 88°
Andru [333]

Answer:

Option (1). 85°

Step-by-step explanation:

From the figure attached,

'l' and 'm' are the parallel lines and line 'n' is a transverse.

Since, m∠9 ≅ m∠13 [These angles are the corresponding angles]

Therefore, m∠13 = 95°

Since, m∠13 + m∠14 = 180° [Supplementary angles]

Therefore, 95° + m∠14 = 180°

m∠14 = 180° - 95°

m∠14 = 85°

Therefore, 85° will be the measure of angle 14.

Option (1) will be the answer.
