Let's check the congruency
Now apply Thales theorem for finding proportion
.

And


Equations are statements that have equal values, when compared
The true statement about
are x = 1 and x = -11
<h3>How to determine the true statement</h3>
The equation is given as:

Rewrite as:

Expand

Factorize

Factor out x + 11

Solve for x
x = 1 or x = -11
Hence, the true statement about
are x = 1 and x = -11

In conclusion:

Hence, our answer is B.
Answer:
P(A and B) = 7/80
Step-by-step explanation:
The given values of the probabilities of the different events are;
P(A) = 7/20
P(B) = 7/20
P(A or B) = 49/80
P(A and B) = Required
We have by probability theory for any event;
P(A or B) = P(A) + P(B) - P(A and B)
Therefore;
P(A and B) = P(A) + P(B) - P(A or B)
Plugging in the values gives;
P(A and B) = 7/20 + 7/20 - 49/80 = 7/80
∴ P(A and B) = 7/80
