To find:
Any two quadratic equations.
Solution:
The general form of a quadratic equation is:

Where, a,b and c are real number and a is non zero.
We know that a,b,c can take any values but a cannot be 0.
For a=1, b=1,c=1, we get


One quadratic equation is
.
For a=3,b=-1,c=5, we get


Therefore, the two quadratic equations are
and
.
Answer:
c
Step-by-step explanation:
i think this is the greatest because if you solve all of the expressions you will find out that this is the greatest.
a.4×-5=-20
b.-5+4=-1
c.-4-(-5)=1
therefore 1 is the greatest so the expression c is the greatest.
I hope this helps
Answer:
L = w + 5
P = 2(L+w) = 42
L + w = 21
w+5 + w = 21
2w + 5 = 21
2w = 16
w = 8 ft
L = w+5 = 13 ft.
Rectangle is 13 ft by 8 ft
Area = 13(8) = 104 ft2
Check: P = 2(L+w) = 2(13+8) = 2(21) = 42 ft
Umm...You gotta draw the angle through y,than look for the 1,then fourths of it then over the 1x then you add 2
Answer:
z = 0
Step-by-step explanation:
Step 1: Write equation
9z - 5 - 4z = -5
Step 2: Solve for <em>z</em>
- Combine like terms: 5z - 5 = -5
- Add 5 to both sides: 5z = 0
- Divide both sides by 5: z = 0
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
9(0) - 5 - 4(0) = -5
0 - 5 - 0 = -5
-5 = -5
