Answer:
Step-by-step explanation:
(3x + 2) - (x + 5)
1(3x + 2) - 1(x + 5)
3x + 2 - x - 5 <== combine like terms
3x - x + 2 - 5
2x - 3 <== final answer, linear binomial
(2x + 8) + (3x² - 2)
1(2x + 8) + 1(3x² - 2)
2x + 8 + 3x² - 2
3x² + 2x + 6 <== final answer, quadratic trinomial
(3x + 8) + (4x² - x)
1(3x + 8) + 1(4x² - x)
3x + 8 + 4x² - x
4x² + 2x + 8 <== final answer, quadratic trinomial
(x² + 5x minus (-) 2) + (8 minus (-) 5x)
(x² + 5x - 2) + (8 - 5x)
1(x² + 5x - 2) + 1(8 - 5x)
x² + 5x - 2 + 8 - 5x
x² + 6 <== final answer, quadratic binomial
(x² + 7x) - (x² + 5)
1(x² + 7x) - 1(x² + 5)
x² + 7x - x² - 5
7x - 5 <== final answer, linear binomial

Answer:
y = 90 meters.
Step-by-step explanation:
It is given in the figure that we have two triangles triangle A and triangle B are similar.
So, .......... (1)
So, the ratio of the corresponding sides of two similar triangles remain same.
Now, x = 75 meters, n = 30 meters and m = 25 meters are given we have to find the value of y.
So, from relation (1), we have
⇒ y = 90 meters. (Answer)
we needed to eliminate w, do so by diving both sides by w and obtain the above result :)
Hope this helps.
