Answer:

Option D. 50 ft

Step-by-step explanation:

we know that

The area of the figure is equal to the area of three rectangles

$A=18x+(48-36)(32-11)+(18)(32)$

$A=18x+(12)(21)+(18)(32)\\A=18x+828$

Remember that the area is given

$A= 1,728\ ft^2$

$18x+828=1,728$

solve for x

$18x=1,728-828\\18x=900\\x=50\ ft$

A trail around a river is 3 1/4 miles long. What is the length, in feet, of the trail?

bezimeni [28]

Answer: 17160 feet

Step-by-step explanation:

We know that 5280 feet = 1 mile

So all we have to do is multiply 3 1/4 by 5280

Let's split the 3 and 1/4 up to make the multiplication easier

3×5280=15840

$\frac{1}{4}$ ×5280= $\frac{5280}{4} =1320$

Now add them together

15840+1320=17160

Evaluate the derivative of f(x) at x = 1. I'll use the limit definition:

$\displaystyle \lim_{x\to1} \frac{f(x)-f(1)}{x-1} = \lim_{x\to1} \frac{6x^2-x^3-5}{x-1} = \lim_{x\to1}(-x^2+5x+5) = 9$

Then using the point-slope formula, the equation of the tangent line to f(x) at the point (1, 5) is

y - 5 = 9 (x - 1)

y = 9x - 4

BRAINLIEST PROMISED! ;)<br><br>IT WILL TELL ME IF YOU ARE WRONG!<br><br>SELECT ALL THAT APPLY!

Triangle ABC:

m∠A = x° (m∠A is represented by x°)

m∠B = (4x)° (m∠B is 4 times greater than m∠A, you know m∠A is x°, so it is (4x)°)

m∠C = (5x - 30)° (m∠C is 30° less than five times m∠A, so it is (5x - 30)°)

A triangle is 180°, so the angles in the triangle should add up to 180°

The second option is FALSE, so everything else is true

Step-by-step explanation:

Moving from left two right, we see "2 times x, less 1." That's Answer a: twice a number decreased by one. Must do the multiplication before the subtraction.
