Step-by-step explanation:
I just did this test and D was the right answer.
Answer:
Option C is correct i.e. 2.
Step-by-step explanation:
Given the function is f(x) = x² +8x -2.
We can compare it with general quadratic expression i.e. ax² +bx +c.
Then a = 1, b = 8, c = -2.
We can find the number of real root by finding discriminant of the equation ax² +bx +c =0 as follows:-
D = b² -4ac
D = 8² -4*1*-2
D = 64 +8
D = 72.
When D is a positive value, then we have two real roots of the equation.
Hence, option C is correct i.e. 2.
Answer:
6
Step-by-step explanation:
Answer:
Option (2).
Step-by-step explanation:
In the figure attached,
Given : TV ≅ WV and UV ≅ XV
To prove: ΔTUV ≅ ΔWXV
Statements Reasons
1). TV ≅ WV 1). Given
2). UV ≅ XV 2). Given
3). ∠XVW ≅ ∠TVU 3). Reflexive property
4). ΔTUV ≅ ΔWXV 4). SAS (Side - angle - side) property of congruence
Therefore, Option (2) will be the answer.
We can find out what LM is based on the fact that the bases of the 2 triangles are the same, this would also mean that the hypotenuse sides of the triangles should also be the same as well. Thus the sides of LM should also equal the sides of MN.
Another way, is to assume that the triangles are right angle ones, and use Pythagorean theorem to solve for the height and use that to solve for the hypotenuse.
