What is the value of x?<br><br> Enter your answer in the box. <br><br> x = ___
lapo4ka [179]
Answer:

x=8

Explanation:

The picture tells us that the triangle is equilateral (this means that each angle is 60°). We can assume this because each side has been marked with the same line.

Because each angle is equal to 60°, this means that:

7x+4=60

Now solve for x:

7x=56
x=8

The figure below is made up of two rectangles.
Dmitry [639]

Answer:

Total area of figure = [3x² + 7x + 6] feet²

Step-by-step explanation:

By dividing both rectangle by vertical line;

Given:

Length of big rectangle = (x + 3) feet

Width of big rectangle = (x + 2) feet

Length of small rectangle = 2x feet

Width of small rectangle = (x + 1) feet

Find:

Total area of figure

Computation:

Area of rectangle = Length x width

Total area of figure = Area of big rectangle + Area of small rectangle

Total area of figure = [(x + 3)(x + 2)] + [(2x)(x + 1)]

Total area of figure = [x²+ 2x + 3x + 6] + [2x² + 2x]

Total area of figure = [3x² + 7x + 6] feet²

A circular running track is 1/4 of a mile long Elena runs this track completing each lap in 1/20 of an hour what is her speed
PSYCHO15rus [73]

Answer:

The speed is equal to 5\frac{mi}{h}

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

x------> the distance in miles

y-----> the time in hours

s----> the speed in mph

so

s=\frac{x}{y}

In this problem we have

x=(1/4)\ mi

y=(1/20)\ h

substitute

s=\frac{(1/4)}{(1/20)}=20/4=5\frac{mi}{h}
