Hello there,
To find the perimeter you add up all 4 sides of the card. The two measurements are 16 and 25 however, this also the case for the other two sides as the card is a perfect rectangle or square.
So 16+16+25+25= 82
The perimeter is 82 cm
Hope this helps!
Answer:
x = ±5
Step-by-step explanation:
x² - 25 = 0
x² = 25
√x² = √25
x = ±5
Check:
5² - 25 = 0
-5² - 25 = 0
25 - 25 = 0
Consider the below figure attached with this question.
Given:
To find:
The number of line that represents the solution of given inequality.
Solution:
We have,
Subtracting 6 from both sides, we get
If an inequality is multiplied or divide by a negative number, then the sign of inequality must be change.
Divide both sides by -4.
The value of x is less than -3. It means number of the left of -3 are included in the solution set but -3 is not included in the solution set.
So, there is an open circle at x=-3 on the number and an arrow from -3 towards left.
Therefore, the correct option is A.
Answer:
a+ 5a = 2a + 9
<=> 6a -2a = 9
<=> 4a = 9
<=> a = 9/4
=> have one solution
