Answer: -11, -3, 17
Step-by-step explanation:
There are three answers depending on what x equals. In this case, x can equal: -2, 0, or 5.
Part 1:
Step 1: Substitute -2 for x
-3 + 4(2)
Step 2: Solve
-3 + 8 = 5
This is the first answer
Part 2:
Step 1: Substitute 0 for x
-3 + 4(0)
Step 2: Solve
-3 + 0 = -3
This is the second answer
Part 3:
Step 1: Substitue 5 for x
-3 + 4(5)
Step 2: Solve
-3 + 20 = 17
This is the third answer
Answer:A
Step-by-step explanation:
Answer:
Below
Step-by-step explanation:
All figures are squares. The area of a square is the side times itself
Let A be the area of the big square and A' the area of the small one in all the 5 exercices
51)
● (a) = A - A'
A = c^2 and A' = d^2
● (a) = c^2 - d^2
We can express this expression as a product.
● (b) = (c-d) (c+d)

52)
● (a) = A-A'
A = (2x)^2 = 4x^2 and A'= y^2
● (a) = 4x^2 - y^2
● (b) = (2x-y) ( 2x+y)
■■■■■■■■■■■■■■■■■■■■■■■■■■
53)
● (a) = A-A'
A = x^2 and A' = y^2
● (a) = x^2-y^2
● (b) = (x+y) (x-y)
■■■■■■■■■■■■■■■■■■■■■■■■■■
54)
● (a) = A-A'
A = (5a)^2 = 25a^2 and A' =(2b)^2= 4b^2
● (a) = 25a^2 - 4b^2
● (a) = (5a-2b) (5a+2b)
■■■■■■■■■■■■■■■■■■■■■■■■■■
55)
● (a) = A - 4A'
A = (3x)^2 = 9x^2 and A'= (2y)^2 = 4y^2
● (a) = 9x^2 - 4 × 4y^2
● (a) = 9x^2 - 16y^2
● (a) = (3x - 4y) (3x + 4y)
Answer:
30.91% probability that he makes exactly three of his next four free throws
Step-by-step explanation:
For each free throw, there are only two possible outcomes. Either he makes ir, or he does not. The probability of making a free throw is independent of other free throws. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Makes 56% of free throws.
So
Assuming free throws are independent, the probability that he makes exactly three of his next four free throws is:
This is P(X = 3) when n = 4. So
30.91% probability that he makes exactly three of his next four free throws
This is my answer.I hope this is useful.
