Answer:

414 yd²

Step-by-step explanation:

The area can be resolved into three rectangles. The figure's area is the sum of the areas of those.

Figure area = sum of LW

= (23 yd)(15 yd) +(3 yd)(3 yd) +(5 yd)(12 yd)

= 345 yd² +9 yd² +60 yd²

= 414 yd²

<h3>Answer: 414 square yards</h3>

========================================================

Explanation:

Surround the entire figure in a bounding rectangle as shown below.

This surrounding rectangle is 23 by 27. It's total area is 23*27 = 621 square yards.

For a moment, let's ignore the 3x3 section marked in the dashed lines. The empty space in the bottom left corner is 15+3 = 18 by 9+3 = 12. Its area is 18*12 = 216 square yards. Accounting for the dash line 3x3 section means we subtract 9 from the 216 to get 216-9 = 207. The empty space takes up 207 square yards.

So the purple region must take up 621-207 = 414 square yards

the sum of three consecutive even integers is 6 subtracted from 4 times the middle number. Find the 3 numbers

anygoal [31]

Answer:

The three consecutive even integers are 4,6,8

Step-by-step explanation:

Let the three consecutive even integers be 2x, 2x+2, 2x + 4

Middle number = 2x +2

2x + 2x+2 + 2x + 4 = 4* (2x+2) - 6

6x + 6 = 4*2x + 4*2 - 6

6x + 6 = 8x + 8 -6

6x + 6 = 8x + 2

6x - 8x = 2 -6

-2x = -4

x = -4/-2

x = 2

The three consecutive even integers are

2x = 2*2 = 4

2x+2 = 2*2 +2 =4 + 2 = 6

2x + 4 = 2*2+4 = 4+4 = 8

How do I solve for X in x/2 + x-3/5= 3

alexandr402 [8]

First of all,we have to cancel off the denominator.

times 2 to the equation in order to cancel off the denominator "2"
(x2) x+2x-6/5=6
#all numbers in this equation will be timed by 2 as well

then times 5 to cancel off the denominator"5"
(x5) 5x+10x-6=30
#all of them are timed by 5

then u will see this equation:
5x+10x-6=30

plus up the unknown numbers,
15x-6=30

Move the negative number "-6" to the back of 30.

When negative number moved to the other side,it will become positive number.
Same as when positive number moved to the other side,it will become negative number.

Thus,
"-6” moved
become positive "6"
Usually positive means plus"+" while negative means minus"-".

15x=30+6
15x=36

Move 15 to the opposite side,
Timed by 15 become divided by 15.

Just like the positive and negative numbers,they forced to become the opposite things.
positive→negative OR negative→positive
plus→minus OR minus→plus
times→divide OR divide→times

Thus,
x=36÷15
OR u can write as fraction,
x=36/15
x=12/5

final ans:
x=12/5 OR 2.4

How do I solve this problem?

nexus9112 [7]

Subtract the second equation from the first equation.
x = -1
Plug -1 back in to either equation and solve for y.
3(-1) + y =-10
-3 + y = -10
Add 3 to both sides
y = -7
CHECK
3(-1) -7 = -10
2(-1) -7 = -9
(-1, -7)

Judi's father is 6 feet tall. how many inches is 6 feet tall

kati45 [8]

One feet is equal to 12 inches, so if we multiply 12 x 6 the answer is 72. So 72 inches equal 6 feet.
