The answer would 282.74km²
Let a, b and c
The lengths of triangle
The sum of two sides will always be larger than the other side.
Then,
| b - c | < a < b + c
| a - c | < b < a + c
| a - b | < c < a + b
To the question A)
a = 83
83 < 40 + 34
83 < 74
False!
____________
Letter B)
a = 51
51 < 33 + 5
False!
___________
Letter C)
a = 50
50 < 31 + 19
False!
____________
Now on the letter D)
a = 29
29 < 18 + 13
29 < 31
It is correct!
Then,
The letter D) would be the answer!

The amount in Ebony's bank account B (d) is a function of the number of days d since she opened the account. The graph shows segments representing.anation:
Answer:
1.
2.
Step-by-step explanation:
One equation is already given in the statement which can give the result.
Lets assume the area of painting = d = 10 sq inch
Now following expressions will give the same answer.
1.
2. Multiplying the percentage d, As the area increases by 49 % which means that D is multiplied by increased amount of 49%
equation will be
3. Calculating the percentage increment = 1/1.49=0.67
Now dividing this value with d will give the same area.
To find how much older Leo is than John, we need to first assign our variables. In this case, let's say that x = Leo, y = Karla, and z = John. Now, let us turn words into numbers.
x = 2y
z = y - 7
Next, we need to create an equation for their combined ages. This is what the equation should look like:
x + y + z = 37
Now, just substitute the expressions we found for x and z. This is what we get:
2y + y + (y - 7) = 37
Solve for y:
2y + y + y - 7 = 37
4y - 7 = 37
4y = 44
y = 11
So now we have the value for y, which is Kayla's age. Therefore, just substitute the value for y back into the equations for x and z.
x = 2(y) => x = 2(11) => x = 22
z = y - 7 => z = 11 - 7 => z = 4
Now that we have the values for x, y, and z, all we need to do now is reassign them back to their respective names. Our final answer will be: John is 18 years older than Leo. The answer to your query would be E) 18. Hope this helps and have a nice day!
