Answer:
165 ft^2
Step-by-step explanation:
We need to break the figure into 2 parts
We have the square at the bottom right
The square is 5 by 5
A = 5*5 = 25
The rectangle is then 20 by (12-5) =7
The area of the rectangle is
A = 20 *7 = 140
Add the areas together
140+ 25
165 ft^2
Answer:
x=−8,y=7
Step-by-step explanation:
The y-intercept would be 25, if you want to find the y-intercept, plug in zero for x!
Let
x---------> the number
we know that
[9+2x]*4=4x+12
36+8x=4x+12
8x-4x=12-36
4x=-24
x=-24/4
x=-6
the answer is
-6
In a quadratic equation
q(x) = ax^2 + bx + c
The discriminant is = b^2 - 4ac
We have that discriminant = 3
If
b^2 - 4ac > 0, then the roots are real.
If
b^2 - 4ac < 0 then the roots are imaginary
<span>In
this problem b^2 - 4ac > 0 3 > 0 </span>
then
the two roots must be real
