Answer:
x = 36
Step-by-step explanation:
<em>A triangle has 180°</em>.
That <em>third angle is 360 - 8x</em>.
So the equation is: <em>180 = 2x + x + 360 - 8x</em>.
Simplify: 180 = -5x + 360
Add/Subtract: 5x = 180
Divide: x = 36.
Descares Theorem says that the number of roots of a polynomial is equal to its highest exponent, and the roots could be real and/or imaginary (complex).
However is their is one complex root (a + i.b), it's conjugate is also
a root (a-i.b).
In the equation x⁴ - 4x³ - 2x² + 12x + 9 = 0, we have already 3 roots, then the 4rth cannot be a complex one since we don't have a fifth for its conjugate.
Step-by-step explanation:
= (11+13+14+15+18+20+23+26)/8
= 140/8
= 17.5
If you enlarge it 6 times, then you get 24in that become 2ft and 36in that become 3ft. If the formula for calculating the area is a times b, then you have to do 2ft x 3ft and you get 6ft2
So the answer is <span>A. 6 ft2</span>
Answer:
x<-3 or x>2, 2<x<-3
Step-by-step explanation:
Subtract/add from each side then divide, if dividing by a negative reverse the sign.
