The area of a rectangular field is given by the trinomial t2 – 4t – 45. The length of the rectangle is t + 5. What is the expres

aniked [119]

The answer is: width = t - 9

A = l * w
A = t² - 4t - 45
l = t + 5
t² - 4t - 45 = (t + 5)w

$w= \frac{ t^{2} - 4t - 45}{t + 5} = \frac{t * t - 9t + 5t - 5 * 9}{t+5} = \frac{t(t - 9) + 5(t - 9))}{t+5} = \frac{(t-9)(t+5)}{t+5} =t-9$

Equation for this slope

Vinvika [58]

Answer:

y=x-3 (assuming your graph is counting by ones)

Step-by-step explanation:

Slope is 1, I chose two points.

0,-3 and 4,1

Then found the slope with those two points, which was 1.

Then I find the y-intercept, which is where the line and point crosses the y axis, which was -3.

So, I made my equation.

SpyIntel [72]

10 Girls

Step-by-step explanation:

Total number of girls in Alden Middle school= 25 girls

Percent of girls play for travel team= 40%

We have to find the numbers of girls who play for middle school team

Numbers of girls who play for middle school team= 25 × $\frac{40}{100}$

Numbers of girls who play for middle school team=25 × $\frac{40}{100}$

Numbers of girls who play for middle school team=10
