The factorization of x2 + 3x – 4 is modeled with algebra
meriva

Option C: (x+4) and (x-1) are the factors of the equation

Explanation:

Given that the equation is x^{2} +3x-4

We need to determine the factors of the equation.

Splitting the middle term, we get,

x^{2} +4x-x-4

Grouping the terms, we have,

x(x+4)-1(x+4)

Let us factor out the term (x+4), we have,

(x+4)(x-1)

Thus, the factors of the equation are (x+4) and (x-1)

Hence, Option C is the correct answer.

Find the value of x in the triangle in the picture.
Flauer [41]

Answer:

X equals 33 degrees

Step-by-step explanation:

Every triangle equals a total of 180 degrees. If you add 114 and 33 you get 147 degrees. You subtract 147 from 180 to get your answer for X, Which is 33 degrees.

Which of the descriptions is true for the graph
Flura [38]

Let's check every choices until one choices satisfy the graph :

Choice A is just a translation of -5 units or 5 units to the left

If we look at the graph between A"B"C" and A'B'C'

A"B"C" is 5 units to the left of A'B'C'

Therefore Choice A is True!

The correct answer is A.

No need to check for the other choices since you got a true statement at the first Choice.

IF in case that A is False, then you need to check the other choices.

Suppose Pr(A)=0.25 and Pr(B)=0.48, where A and B are mutually exclusive. Find Pr(A ? B).
Slav-nsk [51]

Answer:  The required value is P(A ∪ B) = 0.73.

Step-by-step explanation:  Given that A and B are two mutually exclusive events where

P(A)=0.25~~~\textup{and}~~~P(B)=0.48

We are to find the following probability :

P(A ∪ B).

We know that

the intersection of two mutually exclusive events is null event. That is,

A ∩ B = ∅     ⇒  P(A ∩ B) = 0.

From the laws of probability, we have

P(A\cup B)=P(A)+P(B)-P(A\cap B)=0.25+0.48-0=0.73

Thus, the required value is P(A ∪ B) = 0.73.
