He drove 44.9 miles per hour
180
Explanation:
Set a equation of a ratio 120/90=x/135
And calculate!
90x=(120)(135)
90x=16200
x=180
The answer to your question is 3x to the second power -6x+x to the third power +4
the answer i gave you is not yet put in standard form yet though
UT = 3 √3
A = 1/2 *12 * 3√3 = 18√3
18√3 = 6y/2
y = 6√3
Answer:
x²+y²+4x-21=0
Step-by-step explanation:
(x-h)²+(y-k)²=r²
(x--2)²+(y-0)²=(5)²
(x+2)²+y²=25
x²+4x+4+y²=25
x²+y²+4x-21=0
