The correct answer is D
A, B, and C are not true because you can not have sides of a triangle that are negative numbers.

Answer:

The answer is the option D

x=7, y=4

Step-by-step explanation:

we know that

If the triangles are congruent

then

The corresponding sides are congruent

AC=EF, BC=DE

substitute the values

5x-5y=2y+7 ------->5x=7y+7 --------> equation A

6y-8=2y+8 -------> 6y-2y=8+8 -------> y=4

Substitute the value of y in the equation A and solve for x

5x=7(4)+7

x=35/5

x=7

This is the 4th question
gavmur [86]

Answer:

a) There are 9 outcomes.

b) **i have attached the tree diagram**

c) 1/9

d) 1/9

Step-by-step explanation:

Both events (choosing a shirt and choosing pants) are not mutually exclusive (disjoint). Meaning that both events can occur at the same time.

a) For a sequence of two events in which the first event can occur <em>m</em> ways and the second event can occur <em>n</em> ways, the events together can occur a total of <em>m</em> • <em>n</em> ways. So for this problem, you would do 3 • 3 which equals 9.

b) **tree diagram is attached**

c) Because there are two different events occurring (choosing a shirt and choosing pants) you need to multiply using the Multiplication Rule for Independent Events : P(A and B) = P(A) * P(B)

The probability of event A occurring (choosing a red shirt) is 1/3 and the probability of event B occurring (choosing brown pants) is also 1/3.

1/3 * 1/3 = 1/9

d) You would do the same thing here as part c.

The probability of event A occurring (choosing a blue shirt) is 1/3 and the probability of event B occurring (choosing blue pants) is again 1/3.

1/3 * 1/3 = 1/9

I hope this was helpful!! :)

Given complex numbers u and v below,what is uv<br><br> u=7i<br> V=6-i
boyakko [2]

Answer:

7 + 42i.

Step-by-step explanation:

u v = 7i(6 - i)

=  42i - 7i^2    But i^2 = -1 so:

=  42i - 7(-1)

=     7 + 42i.
