The discriminant of y=ax^2+bx+c is b^2-4ac
given
9x^2+10x+0
a=9
b=10
c=0
discriminant=10^2-4(9)(0)=100-0=100
the discriminant is 100
Answer:
The correct answer is m∠2 = 120°
Step-by-step explanation:
There is a triangle rule that states the outer angle of an angle in a triangle is equal to the sum of the remaining two angles in that triangle, which means that m∠2 = 52° + 68° = 120°. This can be proven correct because the sum of two of the angles in the triangle is 120°, which means the final angle is 60°. Since m∠2 is the outer angle of 60°, that means it will be 180° - 60° or 120°.
Answer:
A2: 4*4*4 = 64 cm³; 6*6*6 = 216 cm³; etc...
B2: 7*4.5*4 = 126 cm³; 10.5*6*2 = 126 cm³; etc...
Step-by-step explanation:
So in A2 you have cubes, so l=b=h, and only one has to be given, called the "length of side".
In B2 they are different, hence there are 3 rows with l, b and h. But still you multiply them l x b x h
yes it does have enough to cover the cube
