Answer:5-3x
Step-by-step explanation:
Answer:
17.66
Step-by-step explanation:
3x=53
Divide both sides by 3
x=17.66
The initial velocity is 19 ft/s.
This equation is in the form
h(t) = -16t²+v₀t+h₀, where -16 is the gravitational constant, v₀ is the initial velocity, and h₀ is the initial height.
Our equation is h(t) = -16t²+19t+110. In this equation, the number in place of v₀ is 19, so the initial velocity is 19.
The area is 25, because the length and width are both 5.
5× 5 = 25 (area)
5 + 5 + 5 + 5 = 20 (perimeter)
You're welcome :)
X^2 + 6x = 7
Divide 6 by 2 and square the result and add to both sides of the equation.
6/2 = 3 3^2 = 9 x^2 + 6x + 9 = 7 + 9
x^2 + 6x + 9 = 16
(x+3)^2 = 16
x+3 = +- Sqrt 16) = +-4
x = -3+4 = 1
x = -3-4 = -7
