PLEASE HELP!!!!!
Ne4ueva [31]

Answer:

Equation: 30=2(x-2)+2(2x+3)

x:\frac{14}{3}

Step-by-step explanation:

By definition, the perimeter of a figure can be calculated by adding the lenghts of its sides.

Knowing this, you can write the following equation:

P=2(x-2)+2(2x+3) <em> [Equation 1]</em>

According to the data given in the exercise, the perimeter in feet of the fighter is:

P=30

Therefore, you can substitute this values into<em> [Equation 1]:</em>

30=2(x-2)+2(2x+3)

Finally, you must solve for "x" in order to find its value. This is:

30=6x+2\\\\30-2=6x\\\\\frac{28}{6}=x\\\\x=\frac{14}{3}

The total number of gallons of water in a tank, w, after t minutes is given in this table and the plot.
Katyanochek1 [597]

The equation showing the relationship between w and t is w = 4t

From the table, we have the following points:

(0,0) and (1,4)

Start by calculating the slope (m)

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

So, we have:

m = \frac{4 -0}{1 -0}

Simplify the numerator and the denominator

m = \frac{4}{1}

Divide 4 by 1

m = 4

The equation is then calculated as:

w = m(t - t_1) + w_1

This gives

w = 4(t - 0) + 0

Simplify

w = 4t

Hence, the equation is w = 4t

A builder builds a house on the land that is 20 feet above sea level. If each floor of the house is 9 feet high, how many feet a
dolphi86 [110]

Answer:

29 feet above sea level

Step-by-step explanation:

One floor is 9 feet high, so the top of the first floor will be 9 feet above the ground.

The ground is also 20 feet above sea level, so add 9 to this to find how many feet above sea level the top of the first floor is:

20 + 9

= 29 feet above sea level
