The width of a rectangle measures (7d + 8f) centimeters, and its
Andre45 [30]

The expression which represents the perimeter, in centimeters, of the rectangle is; (18d +10f) centimetres.

<h3>Perimeter of a rectangle</h3>

Since the perimeter of a rectangle is given by the formula;

  • Perimeter, P = 2l + 2w.

In essence, Perimeter, P = 2(2d – 3f) + 2(7d + 8f)

  • P = 4d -6f + 14d +16f

  • P = 18d +10f.

Ultimately, the perimeter of the rectangle is; (18d +10f) centimetres.

Write the equation of the line through the given points : <br> I need help please
Diano4ka-milaya [45]

Answer:

y=-3x+5

Step-by-step explanation:

The equation for slope is:

Slope=\frac{y_2-y_1}{x_2-x_1}

We can substitute the given coordinates into the equation:

Slope=\frac{3-0}{\frac{2}{3}-\frac{5}{3}}=\frac{3}{\frac{2-5}{3}}=\frac{3}{\frac{-3}{3}}=\frac{3}{-1}=-3

The slope is -3

The equation for a line is:

y=mx+b

m: slope

b: y-intercept

x, y: (x, y) coordinate pair

Now, plug in the slope and one of the (x, y) coordinate pairs to solve for the y-intercept.

y=mx+b\\y=-3x+b\\0=-3(\frac{5}{3})+b\\0=\frac{-15}{3}+b\\0=-5+b\\$Add 5 to both sides\\b=5

Therefore the equation is:

y=-3x+5

What is the length of the hypotenuse, c? Round your answer to the nearest hundredth.
BartSMP [9]

Answer:

c=11.180

Step-by-step explanation:

formula to find the hypotenuse (c)= a^2+b^2=c^2

so... 10^2+5^2=c^2, please correct me if I'm incorrect, or made a mistake

100+25=c^2

125=c^2

square it and you get...

c=11.18033988...

c=11.180
