Write a simplified expression using exponents that represents the area of the square.

olganol [36]

Answer:

The area of the square is 25 $d^{2}$ .

Step-by-step explanation:

In the given square, the length of the side = 5d.

Area of a square = side × side

Given: Side = 5d

Now plug in side 5d in the above area formula, we get

Area of the square = 5d × 5d

= 25 $d^{2}$

Therefore, the answer is 25 $d^{2}$ .

Answer:

$57.2\ ft$

Step-by-step explanation:

we know that

The formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)

In this problem

The tangent of angle of 5 degrees is equal to the quotient of "rise over run"

Let

y ----> the rise of the ramp

x ----> the run of the ramp

$tan(5^o)=\frac{y}{x}$

we have

$y=5\ ft$

substitute and solve for x

$tan(5^o)=\frac{5}{x}$

$x=\frac{5}{tan(5^o)}$

$x=57.2\ ft$
