Answer:
SAS congruence theorem
Step-by-step explanation:
since we are given the two congruent sides and the right angle. We know all right angles are congruent and the right angle is an angle that is between the two sides which is why it is SAS. hope this helps :))
Answer:
(x + 4)^2 + 3 = 0
Step-by-step explanation:
When you multiply out (a + b)^2, you get a^2 + 2ab + b^2. We already know the a^2 term, which is x^2. We can deduct the first term of the square is x because x * x is x^2, and x would correspond with a. Next, we can connect the 2ab term with 8x, as it includes the variable x.
2ab = 8x
We have established a = x, so:
2xb = 8x
b = 4
We can put this together to get the square:
(x^2 + 8x + 16) + 3 = 0
(the three is added to get a last term of 19 in the given equation)
When we factor the square, it turns out as:
(x + 4)^2 + 3 = 0
Note: Sorry if the answer was a bit confusing, this is kinda hard to explain.
Answer: b. 1.94
Step-by-step explanation:
For binomial distribution model , the formula to find standard deviation is given by :-
Given : The portability that the offices she visits will eventually purchase her product: p=0.25
The number of offices she visited = 20
We assume that the binomial is an appropriate model for the number of offices that make a purchase.
Then, to find the distance of the possible number of sales Tina could observe from the overall mean number of sales we find standard deviation.
Hence, the correct answer is option (b).
Answer:
77
Step-by-step explanation:
it is the same angle from one side and theother
44, since $48 divided by 66 is .7272 repeating, and .7272 times 44 is 32.
