Solve 3x2 + 4x = −5.

Alla [95]

Move the -5 over by adding 5 to both sides
3x^2+4x+5=0
must use quadratic formula

for an equation in the form
ax^2+bx+c=0
x= $\frac{-b+/- \sqrt{b^2-4ac} }{2a}$

a=3
b=4
c=5

x= $\frac{-4+/- \sqrt{4^2-4(3)(5)} }{2(3)}$
x= $\frac{-4+/- \sqrt{16-60} }{6}$
x= $\frac{-4+/- \sqrt{-44} }{6}$
x= $\frac{-4+/- 2\sqrt{-11} }{6}$
remember that√-1=i
x= $\frac{-4+/- 2i\sqrt{-11} }{6}$
x= $\frac{-2+/- i\sqrt{-11} }{3}$

x= $\frac{-2+ i\sqrt{-11} }{3}$ or x= $\frac{-2- i\sqrt{-11} }{3}$

Ms. galendez's backyard is a rectangle whose length is twice the width. if the perimeter is 720 ft, what are the dimensions of h

Talja [164]

Answer:

120ft and 240ft

Step-by-step explanation:

720 = 2L + 2W

Since L = 2W, we get

720 = 2(2W) + 2W

6W = 720

W = 120

L = 2W = 2(120) = 240

The dimensions of the yard are 120 feet and 240 feet
