What is the factored form of the expression? 3x 2 + 8x – 16A. (3x + 4)(x – 4)
B. (3x + 4)(x + 4)
C. (3x – 4)(x – 4)
D. (3x – 4)(x + 4)

Answers

The correct answer is D. (3x-4)(x+4).

Answer:

The factored form of the expression 3x + 8x – 16 is (3x -4) (x + 4) .

Option (D) is correct.

Step-by-step explanation:

As the expression given in the question be.

$3x^(2) +8x -16 = 0$

$3x^(2) +12x - 4x -16 = 0$

3x (x + 4) - 4 (x +4) = 0

(3x -4) (x + 4) = 0

Therefore the factored form of the expression 3x + 8x – 16 is (3x -4) (x + 4) .

Option (D) is correct.

The cost of a telephone call is 75 cents plus 25 cents per minute. Write an algebraic expression that models the cost of a telephone call that lasts t minutes.

Answers

y=.75x+.25

.75(1)+.25= $1.00
x= the number of phone calls y= the total

75 + 25 x t = Answer

Example:
t= 2 minutes
75 + 25 x 2 = $2.00

A photocopy was made of julie's watercolor painting. the photocopy resized the painting so that it measured 4 inches wide by 7 inches long. if the actual painting is 16 inches wide, what is the length A.28 inches
B.9.14 inches
C.38 inches
D.64 inches

Answers

First, set up a ratio.

4:7= 16:x
You mutiply 4 by 4 to get 16, so you multiply 4 to 7.

4:7= 16:28
Therefore, the answer is A, 28 inches.

Answers

we have

$x^(2) -3x=-8$

Complete the square. Remember to balance the equation by adding the same constants to each side

$x^(2) -3x+1.5^(2)=-8+1.5^(2)$

$x^(2) -3x+1.5^(2)=-5.75$

Rewrite as perfect squares

$(x-1.5)^(2)=-5.75$

Square Root both sides

$x-1.5=(+/-)√(-5.75)$

Remember that

$√(-1)=i$

$√(5.75)= \sqrt{(23)/(4)}=(√(23))/(2)$

Substitute

$x-1.5=(+/-)i(√(23))/(2)$

$x=1.5(+/-)i(√(23))/(2)$

$x=(3/2)(+/-)i(√(23))/(2)$

$x=(3/2)+i(√(23))/(2)=(3+i√(23))/(2)$

$x=(3/2)-i(√(23))/(2)=(3-i√(23))/(2)$

therefore

the answer is

x equals quantity of 3 plus or minus I square root of 23 all over 2

What is the following product?

Answers

Answer & Step-by-step explanation:

(5√2 - 4√3)(5√2 - 4√3)

We can rewrite this equation into a more simpler form.

(5√2 - 4√3)²

Now, we multiply. When multiplying, its important we multiply each term instead of combining them together.

When you multiply a radical by itself, then the base number will be by itself as the product.

So......

(5)² = 25

(4)² = 16

(√2)² = 2

(√3)² = 3

So, now the equation looks like this..

(25 * 2) + (16 * 3)

Multiply the terms.

50 + 48

Add the numbers.

50 + 48 = 98

So, your answer will be answer choice D. The radical in choice D represents the radicals that are in the problem multiplied together.

Which equation is an identity?A. 7m – 2 = 8m + 4 – m

B. 8y + 9 = 8y – 3

C. 11 – (2v + 3) = –2v – 8

D. 5w + 8 – w = 6w – 2(w – 4)

Answers

An identity is obtained when you substitute any value of x to an equation, both sides will give out the same answer. A trial-and-error method is best used for questions like these. The method is shown below:

Let: 1 = m = y = v = w

A. 7m – 2 = 8m + 4 – m

7(1) – 2 = 8(1) + 4 – (1)
5 =/= 11

B. 8y + 9 = 8y – 3

8(1) + 9 = 8(1) - 3
17 =/= 5

C. 11 – (2v + 3) = –2v – 8

11 - (2(1) + 3) = -2(1) - 8
6 =/= -10

D. 5w + 8 – w = 6w – 2(w – 4)

5(1) + 8 -1 = 6(1) - 2(1 - 4)
12 = 12

Therefore, the choice D is the identity.
