(x+4)(x-3)=30
x^2 +x -12 =30
x^2 +x =42
x^2 +x -42 =0
(i solved it by factorising: _x^2 × -42)
x^2 -6x +7x -42 =0
x(x-6) +7(x-6) 0
(x-6)(x+7)=0
x=6; x=-7
since it's a length, x can't be a negative number, so it must be 6
Answer: Need more points.
Step-by-step explanation:
If George's total point is 5 less than susan's points then George needs more points to make up to susan or pass susan's points.
For example ,
g = s - 5 where g is George's points and s is susan's point.
As you can see for G to catch up with s you will need 5 more points.
Complementary angles are the angles whose sum makes 90 degrees. According to the question, the other angle is 14.2 degrees more than the complementary angle. Therefore, 14.2° will be added to the other angle.
Answer:
Correct option: C -> 2%
Step-by-step explanation:
To find this probability we just need to divide the area of the bull's-eye circle by the total area of the outer circle.
The area of a circle is given by the equation:
The outer radius is 14 cm, so:
The inner radius is 2 cm, so:
So the probability is:
Correct option: C
