What is the area of the polygon?
1 answer:
Answer:
Step-by-step explanation:
First, we divide the composite figure into two distinct geometric shapes. This would be a triangle and a square. To find the triangle we use the formula:
A = 1/2bh
To find the base of the triangle we can add:
9 + 9 + 18 = 36
Now we plug in and solve:
A = 1/2bh
A = 1/2(36)(27)
= 1/2(972)
= 486
To find the square, we can use length x width:
18×18 = 324
Now, we add the sums together:
486 + 324 = 810

Answer:
1 - Option C - 10,000
2 - 3x+5 will be 12 more than 3x-7.
Step-by-step explanation:
1) To find : With what number must 3.475817 be multiplied in order to obtain the number 34,758.17?
Solution :
The number 3.475817 is multiplied by number to obtain 34,758.17.
As we see that, the decimal is moved four places to the right.
Which means the number is multiplied by 10000.
i.e.
Therefore, option C is correct.
2) To find : How much greater is the value of 3x+5 than the value of 3x−7?
Solution ;
Assuming that x is the same value in each equation,
In order to determine the difference between the two values,
We ignore the 3x part as it is the same on both of the equations.
So, from 5 to -7 i.e. 7+5=12.
Therefore, 3x+5 will be 12 more than 3x-7.
