Which expression is equivalent to 24x2 - 22x + 5?​

Mathematics
1 answer:
enot [183]3 years ago
4 0

Answer:

C

Step-by-step explanation:

Given

24x² - 22x + 5

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 24 × 5 = 120 and sum = - 22

The factors are - 12 and - 10

Use these factors to split the x- term

24x² - 12x - 10x + 5 ( factor the first/second and third/fourth terms )

= 12x(2x - 1) + 5(2x - 1)  ← factor out (2x - 1) from each term

= (12x - 5)(2x - 1) ← in factored form → C

M<3 is (3x + 4) and m<5 is (2x +11)
butalik [34]

Answer:

Part 1) Option C. Same side interior angles

Part 2) Option A. (3x+4)+(2x+11)=180\°

Part 3) Option B. m

Step-by-step explanation:

Part 1) we know that

If p and q are parallel

then

m<3 and m<5 are consecutive interior angles or Same side interior angles

and

m

Part 2) we know that

m -----> by consecutive interior angles (supplementary angles)

we have that

m

m

so

substitute

(3x+4)+(2x+11)=180\°

Part 3) Find the measure of angle 5

we know that

(3x+4)+(2x+11)=180\°

Solve for x

5x+15\°=180\°

5x=180\°-15\°

x=165\°/5\°=33\°

m

substitute the value of x

m

Find all possible values of k so that x^2 + kx - 32 can be factored.
daser333 [38]

Answer:

Step-by-step explanation:

The posssible factors are

x^2 + 4x - 32

(x+8)(x-4)

x^2+ 14x - 32

(x+16)(x-2)

(x+32)(x-1)

x^2+31x-32

Stolb23 [73]

Answer:

1. 0.1635

2. 0.0026

Step-by-step explanation:

The computation of the probability in the following cases are as follows:

1.

Given that

Mean = 25 minutes

ANd, the standard deviation is 6.1 minutes

So here the z score would be

= (31 - 25) ÷(6.1)

= 0.98

Now the probability is

= P(Z>0.98)

= 0.1635

2. the z score would be

= (8 - 25) ÷(6.1)

= -2.79

Now the probability is

= P(Z<-2.79)

= 0.0026
