So for the first one you would replace Y with what it = which in this case is -x+7So it would look something like this
-x+7=-x+7
1. 180
2. 1&4
3. 1
the answer to the question
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
Answer:
x^2 y^2
Step-by-step explanation:
9x^2y^2/x^2y^2=9
5x^2y^2/x^2y^2=5
since 9 and 5 have no common factors except 1, x^2 y^2
