Finding the greatest common factor ( or G C F ):
G C F is the largest number that divides evenly into all the numbers.
270 : 90 = 3
360 : 90 = 4
G C F ( 270, 360 ) = 90
Answer:
$2215.35
Step-by-step explanation:
27.35*75=2051.25
27.35*1.5=41.025
41.025*4=164.1
164.1+2051.25=2215.35
Answer:
The midpoint is (3,8)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the two coordinates together and divide by 2
( 4+2)/2 = 6/2 = 3
To find the y coordinate of the midpoint, add the two coordinates together and divide by 2
( 7+9)/2 = 16/2 = 8
The midpoint is (3,8)
Ax²+bx+c=0 , a>0, c<0 (or a<0, c>0)
D=b²-4ac ≥ 0 always will be positive
because negative*positive = negative,
a*c -negative, so (-4ac) positive
So,
<span>If, in a quadratic equation, the values of a and c have opposite signs, the solutions of the equation are real numbers.
</span>True
