Original: (3x2 + 5x – 4) – (2x2 – 7x – 1)
3x^2 + 5x - 4 - 2x^2 - 7x - 1 < (Took parenthesis off)
First: Do 3x^2 - 2x^2 = x^2
x^2 + 5x - 4 - 7x - 1
Secondly: Do 5x - 7x = -2x
x^2 - 2x - 4 - 1
Third: Do -4 - - 1 = -4 +1 (Note: Subtracting 2 negatives will make it a positive)
Answer: x^2 - 2x -3
HOPE THIS HELPS! ^_^
Answer:
$3063.6
Step-by-step explanation:
72% of $4,255 = $3063.6
The formula for finding percents is number x percent ÷ 100.
4,255 x 72 ÷ 100 = 3063.6

Answer:
Step-by-step explanation:
Use the quadratic formula:
Simplify:
Answer:
49π
Step-by-step explanation:
The equation of the area of a circle is πr^2
π= 3.14
r= 1/2d
Because d=14 the radius is
r=1/2(14) or r=7
Therefore the equation of the area of the circle is π7^2
Because of the order of operations we can evaluate that 7^2= 49
49*π= 49π
