Answer:d = -3  

Step-by-step explanation:

Simplifying

-7 + -8d = 17


Solving

-7 + -8d = 17


Solving for variable 'd'.


Move all terms containing d to the left, all other terms to the right.


Add '7' to each side of the equation.

-7 + 7 + -8d = 17 + 7


Combine like terms: -7 + 7 = 0

0 + -8d = 17 + 7

-8d = 17 + 7


Combine like terms: 17 + 7 = 24

-8d = 24


Divide each side by '-8'.

d = -3


Simplifying

d = -3

The trinomial did she factor is \rm x^2-4x-12.

Given

Leonora is factoring a trinomial.

The factors of the trinomial are shown on the model.

<h3>Quadratic equation</h3>

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there.

Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

Algebra tiles are tiles used to represent variables or numbers and are rectangular or square-shaped.

1 is labeled + x squared, this gives x².

And 6 are labeled negative. 3 tiles are in the Factor 2 spot:

1 is labeled x and 2 are labeled. 0 tiles are in the Product spot.

-6x + 2x -12

Therefore

The trinomial did she factor is;

\rm x^2-4x-12

Hence, The trinomial did she factor is \rm x^2-4x-12.

More about the quadratic equation link is given below.

saul85 [17]

Answer:

E=3.4363

Step-by-step explanation:

#Given a significance level of \alpha=1-CI=1-0.90=0.1 and

\bar x=36, \ \sigma=12.1 \ n=41, the critical value is,z_\alpha_/_2=z_\alpha_/_0_._0_5=1.645

#the margin of error can then be calculated as:

E=z_\alpha_/_2\times\frac{\sigma}{\sqrt n}=1.645\times \frac{12.1}{\sqrt 33}\\\approx 3.4363

Hence the margin of error is 3.4363
