4x + 18 = 10x
Subtract 4x from both sides
18 = 6x
Divide by the coefficient to get X by itself.
3 = x
Each of the square's sides = 3.
Answer:
Its option A
Step-by-step explanation:
P=2l+2w
P=2(l+w)
P/2=l+w
P/2-l=w
(P-2l)/2=w
Answer:
2c-3y-4=0
Step-by-step explanation:
Standard form is when the answer is equal to zero.
The equation becomes y =-0.7x²+5.4x+6 if the person who is 6 feet tall throws a ball into the air option first is correct.
<h3>What is a quadratic equation ?</h3>
Any equation of the form
Where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
The standard form of a quadratic equation:

Plug x = 0 and y = 6
6 = c ...(1)
Plug x = 1, and y = 10.7
10.7 = a + b + c ...(2)
Plug x = 2 and y = 14
14 = 4a + 2b + c ...(3)
After solving equation (1), (2) and (3) we get:
a = -0.7
b = 5.4
c = 6

Thus, the equation becomes y =-0.7x²+5.4x+6 if the person who is 6 feet tall throws a ball into the air option first is correct.
