Answer:
3 ft 9 in
Step-by-step explanation:
Answer:
1 2 real
2. No real
3. 2 Real
4. One real Multiplicity 2.
Step-by-step explanation:
Find the value of the discriminant D (b^2 - 4ac) :-
1 . D = (1)^1 -4 * -3 * 12 = 1 + 144 = 145
D is positive so there re 2 real solutions.
2. D = (-6)^2 - 4*2*5 = 36 - 40 = -4
D is negative so there are NO real solutions.
3. D = (7)^2 - 4 * 1 * -11 = 49 + 44 = 93
2 real
solutions
4. D = (-8)^2 - 4* -1 * -16 = 64 - 64
1 solution. Multiplicity 2.
In a circle, the parts of the diagonals multiply to equal each other, so 6·4=2x.
2x = 24, x = 12.
We start with m < A + m < B = m < B + m < C as the given equation. We can rearrange the two terms on the right hand side to get m < A + m < B = m < C + m < B. From here, subtract m < B from both sides to end up with m < A = m < C. The angle B terms go away entirely. This rule I used was the subtraction property of equality. The next rule to use is the symmetric property to go from m < A = m < C to m < C = m < A. This rule is basically where we can flip the two sides of the equation and the equation is the same.
