Select the correct answer. Factor the expression. A. (7x − 4)(7x − 4) B. (4x − 7)(4x − 7) C. (7x + 4)(7x − 4) D. (4x + 7)(4x − 7)

Answers

Answer:

C. (7x + 4)(7x − 4)

Step-by-step explanation:

Given expression:

49x² - 16

Using difference of two squares:

A² - B² = (A + B)(A - B)

49x² - 16 = (7x)² - (4)²

= (7x + 4)(7x - 4)

C. (7x + 4)(7x − 4)

Check:

(7x + 4)(7x − 4)

Open parenthesis

= 49x² - 28x + 28x - 16

= 49x² - 16

janelle practices basketball every afternoon in driveway.Each day,her goal is to make 4 more baskets than she made the day before. if she makes 10 baskets the first day and meets her goal for 2 weeks,howmany baskets will janelle make on the 14th day?

Answers

In the given question, there are several information's worth noting. Based on these given information's the actual answer to the question can be found. She makes 10 baskets on the first day and then increases the number of baskets by 4 on every consecutive days. So the thing that needs to be found is the number of baskets he makes on the 14th day. This is an arithmetic progression problem.
Now if we consider the 14th day as the Nth term, then we can write the equation as
A(N) = 4(N - 1) + 10
A(14) = 4(14 - 1) + 10
A(14) = (4 * 13) + 10
         = 52 + 10
         = 62
So Janelle will make 62 baskets on the 14th day.

Write an equation in standard form for a line that passes through (4,1) & (5,7)

Answers

y = mx + b

First equation 1 = m(4) + b, bring everything to one side m(4) + b - 1 = 0
Second equation 7 = m(5) + b, bring everything to one side m(5) + b - 7 = 0

Set them equal to each other, 

m(4) + b - 1 = m(5) + b - 7

If you bring the b over to the left hand side it becomes

m(4) + b - b - 1 = m(5) - 7

m(4) - 1 = m(5) - 7

Solve for m

6 = m

Plug m = 6 into either equation from the beginning,

m(4) + b - 1 = 0

6(4) + b - 1 = 0

24 + b - 1 = 0

b = -23

Knowing m and b we can now make an equation

y = mx + b

y = 6x -23 Final answer



Find the sum of (5x3 + 3x2 - 5x + 4) and (8x3 -5x2 + 8x + 9).

Answers

If you would like to solve (5 * x^3 + 3 * x^2 - 5 * x + 4) + (8 * x^3 - 5 * x^2 + 8 * x + 9), you can calculate this using the following steps:

(5 * x^3 + 3 * x^2 - 5 * x + 4) + (8 * x^3 - 5 * x^2 + 8 * x + 9) = 5 * x^3 + 8 * x^3 + 3 * x^2 - 5 * x^2 - 5 * x + 8 * x + 4 + 9 = 13 * x^3 - 2 * x^2 + 3 * x + 13

The correct result would be 13 * x^3 - 2 * x^2 + 3 * x + 13.
(5x^3+3x^2-5x+4)+(8x^3-5x^2+8x+9)=\n\n13x^3-2x^2+3x+13
