Step-by-step explanation:
You can tell that the angles and length of the triangles are equal from the marks. For example, angle J has 2 lines on its angle so i looked for the other angle with 2 lines on it which happens to be angle S.
Comment if u dont understand

Answer:
0.012
Step-by-step explanation:
Linear approximation says that,
For a cube the surface area is 
.
So the side is 1.0 inch in, the surface area is 
square inches.
In Linear approximation means you ignore the term 
, if 
is a small number, because then will be a very smalle number and that does not contribute much to the error.
So the surface area is approximately,
So here, 
The error in the area is approximately,
So the error is 0.012.
Answer:
none of the answer above
Step-by-step explanation:
it should be
16x +8 or 8(2x+y)
group the number together according to alphabet and number
We have to present the number 41 as the sum of two squares of consecutive positive integers.
1² = 1
2² = 4
3² = 9
4² = 16
5² = 25
16 + 25 = 41
<h3>Answer: 4 and 5</h3>
Other method:
n, n + 1 - two consecutive positive integers
The equation:
n² + (n + 1)² = 41 <em>use (a + b)² = a² + 2ab + b²</em>
n² + n² + 2(n)(1) + 1² = 41
2n² + 2n + 1 = 41 <em>subtract 41 from both sides</em>
2n² + 2n - 40 = 0 <em>divide both sides by 2</em>
n² + n - 20 = 0
n² + 5n - 4n - 20= 0
n(n + 5) - 4(n + 5) = 0
(n + 5)(n - 4) = 0 ↔ n + 5 = 0 ∨ n - 4 =0
n = -5 < 0 ∨ n = 4 >0
n = 4
n + 1 = 4 + 1 = 5
