Area of the rectangle = 5.4 x 2.6 = 14.04 mm²


Length of a square that has area 14.04 mm² = √14.04 = 3.75 mm


Answer: (A) 3.75 mm

Hey!


Area is equal to length × width. First find the area of the rectangle.


5.4 \times 2.6 = 14.04


The area of the rectangle is 14.04 mm². That means the area of the square is also 14.04 mm². In a square, all 4 sides are the same. The length and width are the same.


Try all choices and see which is the closest


3.75 \times 3.75 = 14.06

3.87 \times 3.87 = 14.98

4.01 \times 4.01 = 16.08

4.32 \times 4.32 = 18.66


The 1st choice is the closest.


\framebox{Your answer is A}

Three students are working to find the solution set of this system of equations: y = 3x + 10 2y = 6x – 4
ivanzaharov [21]

Answer:

Step-by-step explanation:

Since this is a system with two equations, we can easily use a graphing calculator to find the solution

The intersection between the graphs of the equations

y = 3x + 10

2y = 6x – 4   (if we divide by two)

y = 3x - 2

However, we can see that the graphs have the same slope m = 3

Since both equations are not equal, there is no solution for this system

Please see attached graph. The lines are parallel and they never touch each other.

Express it in slope-intercept form.
vekshin1

Answer:

y=(2/3)x+1

Step-by-step explanation:

Slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.

To find the slope, we need two points. From the graph, we can see that (0,1) and (3,3) are valid points.

(0,1) is coincidentally also the y-intercept, so b=1.

The slope is (3-1)/(3-0)=2/3

The equation of the line is thus:

y=(2/3)x+1
