Step-by-step explanation:

You divide the polygon into smaller shapes, rectangles suit this best.

There will be 2 rectangles:

1st rectangle whose length is 24ft and its width is 11 ft (21-10=11).

2nd rectangle its length is 10ft and its width is 7ft.

You find the area of both rectangles. The formula of finding the area of a rectangle is length X width.

1st rectangle has an area of 264 ft² (24 X 11)

2nd rectangle has an area of 70ft² (10 X 7)

Add the area of the two angles to get the area of the polygon.

Answer:

Question 4: Which equation is parallel to the above equation and passes through the point (35, 30)

$y=$ $\frac{5}{7} x + 5$ is the correct answer, I found this by inputting the x and y value of the coordinate (35, 30) onto the equation and solving for y-intercept since the slope of all equations is the same (since it's traveling parallel)

$30 = \frac{5}{7} (35) + y\\30 = 25 + y\\5 = y$

so the equation would be $y=$ $\frac{5}{7} x + 5$

Question 5: Which equation is perpendicular to the above equation and passes through the point (35, 30)

$y=\frac{-7}{5} x+79$ is the correct answer, I found this using the same method as before, input coordinate values into the equation and solve for the y-intercept (The only thing changed from the last answer is the opposite reciprocal slope).

$30 = \frac{-7}{5}(35) + y \\30 = -49 + y \\79 = y$

so the equation would be $y=\frac{-7}{5} x+79$

Hunter-Best [27]

Answer:

12 ≠ 14

Step-by-step explanation:

(4+8)=2+(6x2)

12 = 2 + 12

12 ≠ 14.

So the equation is false.

Two girls had 45.00 to spend. one spent 6 dollars less than twice the other. solve

Varvara68 [4.7K]

Let, money spend by jane = x

Maggie spend = 2x-6

So, x+2x-6 = 45

3x= 51

x=17, 2x-6 = 28

So, jane spend $17 & Maggie spend $28
