Area of a rhombus = 1/2 x diagonal 1 x diagonal 2
= 1/2 x 15 1/2 x 13 1/5
= 1/2 x 31/2 x 66/5
=31/2 x 33/5
= 1023/10
= 102.3
Final Answer: 102.3 square feet
Answer:
8
Step-by-step explanation:
Let the number be n
6*n = 16 + 4*n
6n = 16 + 4n
6n - 4n = 16
2n = 16
2n/2 = 16/2
n = 8
1.


Multiply both sides by x:

Subtract from both sides Gx:

Then solve this equation:

2.


Multiply both sides by x:

Subtract from both sides Gx:

Then solve this equation:
Answer:
Part A: 2k(2c2+5(2)-8c-20)
Part B: sorry i don't know how to do this part
Step-by-step explanation:
Part A, you divide each number by 2 first so you get a simplified version of each number. Then, you will quickly realize that the varible k is similar in all of the numbers then you remove that and put it with the 2 outside the (). Hope you understood my explination.
Acute-The angle is less than 90 degrees
Equilateral-All sides are equal in length
Isosceles-Two of the sides are equal in length
Scalene-None of the sides are equal in length
Right-The angle is 90 degrees
Obtuse-The angle is greater than 90 degrees
We can see that none of the sides are the same length, so we know that it must be scalene. We can also see that every angle is less than 90 degrees, so we know that is must be acute.
The triangle is scalene and acute.
Hope this helps!!
