Find the area hurry plss
erica [24]

Answer:

114m^2

Step-by-step explanation:

At first it looks like you can split this into 3 rectangles, but the easier way is to subtract the area that is cut out from the larger rectangle. In this image, we have an outer rectangle that measures 12m x 14m. In the middle, there is a 9x6 rectangular hole. Subtract the area of the hole from the total area of the rectangle.

Total area = 12 * 14 = 168

Area of hole = 6 * 9 = 54

Area left = Total area - Area of hole

              = 168 - 54

              = 114m^2

What are the steps to this equation
Harlamova29_29 [7]

Answer:

x=7

Step-by-step explanation:

\frac{2}{5}x+\frac{1}{3}=\frac{1}{3}x+\frac{4}{5}

Subtract \frac{1}{3} from both sides:

\frac{2}{5}x+\frac{1}{3}-\frac{1}{3}=\frac{1}{3}x+\frac{4}{5}-\frac{1}{3}

\frac{2}{5} x=\frac{1}{3}x+\frac{12}{15}-\frac{5}{15}

\frac{2}{5}x=\frac{1}{3}x+\frac{7}{15}

Subtract \frac{1}{3} x from both sides:

\frac{2}{5}x-\frac{1}{3}x=\frac{1}{3}x+\frac{7}{15}-\frac{1}{3}x

\frac{6}{15}x-\frac{5}{15}x=\frac{7}{15}

\frac{1}{15}x=\frac{7}{15}

Multiply both sides by 15:

15\times \frac{1}{15}x=\frac{7\times 15}{15}

x=\frac{105}{15}

x=7

Write the equation for a line perpendicular to y=-3x+18 that goes through the point (-12,6)
Hatshy [7]

Answer:

y=\frac{1}{3} x -14

Step-by-step explanation:

The equation of the line you will find should be in the form y =mx+c , where m is the gradient and c is the y intercept.

The gradient of a line that is perpendicular to a line [of a known gradient] is the negative reciprocal of the gradient of the first. i.e. if a is the known gradient and the perpendicular gradient is b, ab = -1. Therefore the -3b=-1 and b= 1/3

you can now write y = mx +c as y = 1/3x +c

As you have been given a coordinate, you can input these values into y= 1/3x + c

-12 = 1/3(6) +c

-12 - 2 = c

c = -14

hence the equation of the line is y= 1/3x -14
