Y=6x−11 y=x²+4x−10
6x−11=x²+4x−10
6x-11-x-4x+10=0
2x-1-x²=0
-(1-2x+x²)=0
-(1-x)2=0
1-x=0
x=1
Plug x into 6x -11=x²+4x-10
6x-11=x²+4x-10
6(1)-11=(1)²+4(1)-10
6-11=1+4-10
-5 = -5
y= -5
<span>Let y= original side
So
A = LW
60 = (y+15)(y-13)
(y+15)(y-13) = 60
y^2 + 2y - 195 = 60
y^2 + 2y- 195 - 60 = 0
y = -17 or y= 15
Toss out the negative solution to get y= 15 as the only solution.
So the square has a side length of 15 meters.
The area of this square is 15^2 = 15*15 = 225 square meters.</span>
Answer:
3
Step-by-step explanation:
first you would solve 2^3. It is 2x2x2 which is 8. Then you do 20-8 which equals 12. Then to finish it off you do 12/4 which is 3
Step-by-step explanation:
y=107(vertically opposite angles)
x=180-107=73(angles on a straight line)
z=73(vertically opposite angles)
