Answer:
28.246
Step-by-step explanation:
hihi. So you can use the Pythagorean theorem to find any missing sides to a triangle. The equation goes like this: a^2 + b^2 = c^2, where a a and b are the lengths of the 2 bases of the triangle and c is the length of the hypothenuse/longest side to the triangle. Since you know the length of the hypothenuse and of one of the bases you can solve for the last base using the equation which gets you ~8.246. Now, adding that to the other side lengths gets you 28.246 as an approximate perimeter to 3 sig figs
Answer:
D
Step-by-step explanation:
Let us assume the two numbers to be "x" and "y".
Then
xy = - 24
x = - (24/y)
And
x + y = 2
Putting the value of x from the first equation in the second equation, we get
x + y = 2
- (24/y) + y = 2
- 24 + y^2 = 2y
y^2 - 2y - 24 = 0
y^2 - 6y + 4y - 24 = 0
y(y - 6) + 4(y - 6) = 0
(y - 6) (y + 4) = 0
When
y - 6 = 0
y = 6
Then
x + y = 2
x + 6 = 2
x = 2 - 6
= -4
And when
y + 4 = 0
y = -4
Then
x + y = 2
x - 4 = 2
x = 2 + 4
= 6
So the two unknown numbers are -4 and 6.
Answer:
4
Step-by-step explanation:
-3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11.
These are the numbers -3, and 11, and every number in between them.
The number in the very middle of these numbers is 4.
