Answer:
7n + 14 and 7(n + 2)
Step-by-step explanation:
We know that since our triangle is isosceles, then two of the sides are the same. Given in the problem, we know that these two congruent sides are both 2n + 7. We also know the third side is 3n.
Perimeter is essentially just the sum of the side lengths of the figure. We simply need to add 2n + 7, 2n + 7, and 3n together:
P = 2n + 7 + 2n + 7 + 3n
Combine like terms:
2n + 2n + 3n + 7 + 7
7n + 14
That's one way we can write it. Another way is to factor out the 7:
7n + 14 = 7(7n/7 + 14/7) = 7(n + 2)
Thus, our two expressions are: 7n + 14 and 7(n + 2).

It would be A because the scale factor is 3 so 10x3=30 (side A) and 13x3=39 (side B)
Answer:
81
Step-by-step explanation:
Substitute 3 in place of y
7 * 3 * 3 - 16 + 5 * 3 *2 + (16 / 4)
63 - 16 + 30 + 4
Answer:
Option (3)
Step-by-step explanation:
From the figure attached,
AB and CD are two chords intersecting at O.
m∠AOD = 37°
m∠AOC + m∠AOD = 180° [Since these angles are supplementary angles]
m∠AOC = 180° - 37°
= 143°
By the theorem of intersecting chords,
Measure of angle formed is the half of the sum of measures of the arcs intercepted by the angle and vertical angle.
m∠AOC =
143° =
143° = x
Therefore, Option (3) will be the answer.
There are 2 of 5 students that do not eat breakfast. This can be represented as 2/5. To find how many did not eat breakfast, you multiply 2/5 by 2500.
This gives you 1,000.
Therefore, 1,000 students surveyed did not eat breakfast.
Hope this helps!
