I hope this helps you
width w
lenght 2w
perimeter =2 (width +length )
60=2 (w+2w)
30=3w
w=10
Area= 2w.w
Area = 2.10.10
Area =200
Standard quadratic equation .. y = a x^2 + b x + c
<span>parabola 'a' not equal to zero </span>
<span>a<0 parabola opens downward </span>
<span>a>0 parabola opens upward </span>
<span>when |a| >>0 the parabola is narrower </span>
<span>when |a| is close to zero , the parabola is flatter </span>
<span>when the constant is varied it only effects the vertical position of the parabola , the shape remains the same</span>
Answer:
Step-by-step explanation:
15 + 720 is 1120
Answer:
0x+2y=22
Step-by-step explanation:
Set them equal to each other, (5x+4y=25)-(5x+2y=3). Distribute the negative into the right equation, (5x+4y=25)(-5x-2y=-3). Then combine like terms to get your answer.
The angles of a triangle always equal 180.
You do 180 - 80 - 45. X = 45.
