Remove the brackets
6 - t + 7 - t - 4 + t = 0
Eliminate the two opposite t because they cancel out to each other
6 + 7 - t - 4 = 0
Add and subtract
6 + 7 - 4 = 9
Thus:
9 - t = 0
Bring the 9 over to the 0 to isolate the -t
-t = 0 - 9
Calculate:
-t = -9
To get rid of the negative on the variable we have to divide it by -1 to make it positive bc negative divided by negative equals positive. Since we are dividing -1 to the -t we also have to divide -9 by -1.
t = 9
I think it is because it goes through the line tell me if I’m right
Well hello again :3. This is also quite simple. The diameter of a circle is 2 times the radius. So we can refit this into the equation and say that our new formula using diameter is
. Now we can say that 10/2 is 5 and
is 25. Therefore your answer is
or 78.54.
Answer:
A. 5x^2 − 2x − 24 = 0
Step-by-step explanation:
height = 5b-2
b =x
We can rewrite the height as
h = 5x-2
We know the formula for area of a triangle
A = 1/2 bh
A =1/2 x * (5x-2)
Distributing the x
A= 1/2 (5x^2 - 2x)
We know A =12
12 = 1/2 (5x^2 - 2x)
Multiply each side by 2
12*2 = 2*1/2 (5x^2 - 2x)
24 = 5x^2 - 2x
Subtract 24 from each side
24-24 = 5x^2 - 2x-24
0 = 5x^2 - 2x-24
