Answer:
area = 26 cm²
Step-by-step explanation:
The formula for the area of a triangle is: area =
Where b = the length of the base and h = height.
In the given problem h = 4 cm and b = 13 cm, so we can plug these values into the equation and multiply:
area = .
Distribute -1 to all terms within the parenthesis
-(9x + 5) = -9x - 5
7x - 9x - 5
Simplify. Combine like terms
(7x - 9x) - 5
-2x - 5 is your answer
hope this helps
1/3x7/8 is the answer give me a thank plz
Answer:
86
Step-by-step explanation:
Let the number be 10x + y. So, the reversed number is 10y + x.
The sum is 154.
So, (10x + y) + (10y + x) = 154
⇒ 11x + 11y = 154
⇒ x + y = 14 ..... (1)
Again, given that ones digit in the original number is 2 less than the tens digit.
So, y = x - 2 ...... (2)
Now, solving (1) and (2) we get,
x + x -2 = 14
⇒ 2x = 16
⇒ x = 8
So, from equation (2), y = x - 2 = 8 - 2 = 6
Therefore, the original number is 10x + y = 10 × 8 + 6 = 86 (Answer)
To find the length of segment AC, we must find the total rise and total run between the two points.
Point C is located at (-5, 5). Point A is located at (3,-1). To find the rise, subtract the y-value of A from the y-value of C:
The rise of this segment is 6.
To find the run, subtract the x-value of A from the x-value of C:
The run of this segment is 8.
We can use the Pythagorean Theorem to find the length of this segment. The theorem uses the following formula:
The segment represents the hypotenuse, and the rise and run represent the legs of this segment. We know that the two legs' lengths are 6 and 8, so plug them into the equation:
Square root both sides to get c by itself:
The length of segment AC is
10.
