Answer:
11: A 12: B
Step-by-step explanation:
-29 <-21 and a coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression
Let s represent the short side of the triangle. The long sides of the triangle are each s+1, and the triangle's perimeter is
... s + (s+1) + (s+1) = 3s+2
The length of one side of the square is s-2, and its perimeter is 4 times that, 4(s-2) = 4s-8. The square and triangle have the same perimeter, so
... 3s+2 = 4s-8
... 10 = s . . . . . . . . add 8-3s to both sides
The length of the shorter side of the triange is 10 units.
Answer:
1
Step-by-step explanation:
You "complete the square" by adding the square of half the x-term coefficient. Here, that is ...
((-2)/2)² = 1 . . . . value added to complete the square
If you want to keep 0 on the right, you must also subtract this value:
x² -2x -36 = 0
x² -2x +1 -36 -1 = 0 . . . . . . add and subtract 1 on the left
(x -1)² -37 = 0 . . . . . . . . . . . written as a square
Answer:
x < -1.8
Step-by-step explanation:
First, subtract 2.4 from each side, you will get 3x > -5.4
Second, divide by 3 on both sides, this will make the > turn into <.
Finally you will end up with x < -1.8.

Answer:
q = -5
q = 5
Step-by-step explanation:
Since there is no constant value. This must be a special case.
So,
(q+5
)(q-5
)
q = -5
q = 5
