Answer:

x-6

Step-by-step explanation:

The formula for the area of a rectangle is (l)(w)

x-5(w)=x²-11x+30

To solve, you need to put the quadratic equation into standard form

x-5(w)=(x-5)(x-6)

Divide both sides of the equation by x-5 to isolate the width(basically strike out x-5 on both sides)

the width is x-6

I pretty sure that's the right answer since (x-5)(x-6)=x²-11x+30, but I'm in geometry right now, and I had to go back and re-learn.

(3)- The change in annual sales ($1000) for every year of experience is= 3.4

(4)-r^2=~ 0.847

Estimated annual sales= $110514

Step-by-step explanation:

(1)- b1 = 3.4606

=~3.4

bo = 82.8296

= ~ 82.8

(2)-

ý=[82.8]+[3.4] x

(3)-The change in annual sales ($1000) for every year of experience is= 3.4

(4)- r^2 = 0.84776

=~ 0.847

Percentage of the variation in annual sales can be explained by the years of experience

of the salesperson 84.7%.

Estimated annual sales

= 82.8296 + 3.4606 × 8 ($ 1000).

= 110.5144 ( $1000)

= $ 110514:4

= $110514

IRISSAK [1]

Answer:

x = 10

Step-by-step explanation:

In the last step, you can see that the fraction \frac{1}{5} has been multiplied by its reciprocal \frac{5}{1}, making it cancel out. The reciprocal has been multiplied to both sides, so all you need to do is multiply \frac{6}{3} · \frac{5}{1} :

6 · 5 = 30

3 · 1 = 3

<u><em>So now you should have the fraction:</em></u>

x = \frac{30}{3}

<u><em>But, you can still simplify the fraction by dividing 30 by 3:</em></u>

x = 10
