Answer:
x1= -9/2 ; x2= -7/3
Step-by-step explanation:
Rewrite to 6x^2 + 27x +14x +63 = 0
Factor and get 3x(2x + 9) + 7(2x + 9) = 0
Factor again and get (2x + 9)(3x + 7) = 0
Separate into possible cases -> 2x + 9 = 0; 3x + 7 = 0
The equation has two solutions: x1 = -9/2 and x2 = -7/3
Hope this helped!!
The answer is 70.364. Go to Cymath and put in the exact equation above and you’ll get each step in full detail. Hope this helps!
60/360*pi*6^2=6pi. (Area of a sector)
1/2*6*6*sin(60)=9root3. (Area of a triangle)
So it must be the top one
The ordered pairs which is the solution of the system of Inequalities is;
x > 0 and y < 2
<h3>How to find the ordered pair of inequalities?</h3>
We are given the inequalities;
x + 2y > 4 ----(1)
3x - y < 2 -----(2)
Subtract 2y from both sides in eq 1 to get;
x > 4 - 2y ----(3)
Put 4 - 2y for x in eq 2 to get;
3(4 - 2y) - y < 2
12 - 4y - y < 2
12 - 5y < 2
Subtract 12 from both sides to get;
-5y < -10
Divide both sides by -5 to get;
y < 2
Put 2 for y in eq 3 to get;
x > 4 - 2(2)
x > 0
