Answer:
2a + 7b + 4
Step-by-step explanation:
4a + 8 - 2a - 4 + 7b
<u><em>Group like terms</em></u>
4a - 2a + 7b + 8 - 4
<u><em>Add similar elements (4a - 2a)</em></u>
2a + 7b + 8 - 4
<u><em>Add/Subtract (8 - 4)</em></u>
2a + 7b + 4
Yes it is possible.
let's take a rectangle with 2 sides of 8 and 2 sides of 4
the area would be 32
and the perimeter would be 24
now, let's take another rectangle with 2 sides of 16 and 2 sides of 2
the area would be 32
and the perimeter would be 36
the areas are the same, but the perimeters are different.
therefore, it is possible.
Euler's method is a procedure for solving differential equations with an initial value. The formula for Euler's method establishes the basic relationship between trig functions and complex exponential functions.
Euler's formula is:
![r=m-v+2](https://tex.z-dn.net/?f=r%3Dm-v%2B2)
In this case, r represents faces, v represents vertices and m is equal to edges, therefore, we have the following:
Answer:
1,120 yd²
Step-by-step explanation:
Surface area of the triangular prism = (bh) + (s1 + s2 + s3)*L
Where,
b = 15 yd
h = 8 yd
s1 = 17 yd
s2 = 15 yd
s3 = 8 yd
L = 25 yd
Substitute
Surface area = (15*8) + (17 + 15 + 8)*25 = 120 + 40*25 = 120 + 1,000
Surface area = 1,120 yd²
