Which of the binomials below is a factor of this trinomial?
x² + 14x + 40
O AX-9
O B. 32 + 10
O C. X* 14
D. X+4.

Answers

Answer:

D. x + 4

Step-by-step explanation:

Let's factor the trinomial:

x² + 14x + 40 = x² + 4x + 10x + 40 = x(x + 4) + 10(x + 4) = (x + 4)(x + 10)

x + 4 is between the answer options

Correct option is D.

Answer:

P1P2 = P1P3 = 2√2P2P3 = 4isosceles right triangle (both)

Step-by-step explanation:

The length of a side can be found using the distance formula:

  d = √((x2 -x1)^2 +(y2 -y2)^2)

For P1P2, this gives ...

  d = √((0-(-2))^2 +(1-(-1))^2) = √(4+4) = √8

  P1P2 = 2√2

__

The same ∆x and ∆y apply to P1P3, so we know ...

  P1P3 = 2√2

__

The lengths of P1P2 and P1P3 are the same, so the triangle is isosceles.

__

The length of P2P3 can be found by subtracting the y-coordinates:

  P2P3 = 1 -(-3)

  P2P3 = 4

__

We note that the slope of P1P2 is 2/2 = 1, and the slope of P1P3 is -2/2 = -1. The product of these slopes is (1)(-1) = -1, so we know those lines are perpendicular. The triangle is a right triangle.

b. The school spent $500 on calculators. How many did the school buy?

Answers

Answer:

Step-by-step explanation:

If he school bought 16 calculators they would pay 500 dollars because if you will  divide 500 by 31.25 you will get an answer of 16

A. $31.25(x)=amount paid
B. $31.25(x)=$500
Divide $500 by $31.25 to cancel each other out
X≈16.5289 which in real world problems would equal 16

Solve the equation for all values of x in simplest form (x + 3)^2 = -16

Answers

Answer:

x = -7 or  x = 1

Step-by-step explanation:

Given expression:

    (x + 3)²  = -16

 

Problem;

   Solve for x;

Solution:

 To solve for x; we use the factorization method;

     Take -16 to the left of the equation;

      (x + 3)²  = -16

         (x + 3)² + 16 = 0

       (x+ 3)² + 4²  = 0

if    x² + y²  = (x + y)(x - y)

     So;

       (x + 3 + 4) (x + 3 - 4) = 0

       (x + 7)(x - 1) = 0

       x + 7  = 0 or x - 1 = 0

      x = -7 or  x = 1

WILL GIVE BRAINLIEST! What is the equation of the line passing through the points (4, 7) and (7, 13) in slope-intercept form?

Answers

Answer:

y = 2x - 1

Step-by-step explanation:

To get slope:

m = y2 - y1 / x2 - x1

m = 13 - 7 / 7 - 4

m = 6 / 3

m = 2

To get y-intercept:

y = mx + b

13 = 2(7) + b

13 = 14 + b

13 - 14 = b

-1 = b

Put it together:

y = 2x - 1
