Answer:
X=-2or,-3
Step-by-step explanation:
X^2+5x+6=0
or,x^2+(2+3)x+6=0
or,x^2+2x+3x+6=0
or,x(x+2)+3(x+2)=0
or,(x+3) (x+2)=0
Either,
x+3=0 x+2=0
or,x=-3 or,x=-2
Therefore,the value if x is -2 or -3 .

If you want to make 12 cookies (one dozen), you would use 3/8 cup of sugar because the original recipe requires twice that amount of sugar and also makes twice that amount of cookies.
Answer:
0.62kg
Step-by-step explanation:
Let
x = 40/kg coffee
y = 11/kg coffee
two equations can be derived from the question
x + y = 12 equation 1
40x + 11y = 114 (9.5 x 12) equation 2
multiply equation 1 by 11
11x + 11y = 132 equation 3
subtract eqn 3 from eqn 2
29x = 18
divide both sides of the equation by 29
x = 0.62kg
Answer:
21°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
subtract the sum of the 2 given angles from 180 for the other angle
other angle = 180° - (90 + 69)° = 180° - 159° = 21°
