Answer:
5(3x + 5) or 15x + 25
Step-by-step explanation:
A regular pentagon has 5 sides of equal length. The perimeter is the sum of the lengths of those sides. We can use multiplication to find the sum of 5 of the same value:
P = 5(3x +5)
Perhaps you want it expanded. Using the distributive property, we multiply each term in parentheses by 5:
P = 15x + 25
Answer:
9
Step-by-step explanation:
You divide 3 by 4 first and you'll get the anser 0.75, then multiply it by 12.
The perpendicular would be -1/4
Answer:
no solution.
Step-by-step explanation:
The given equation is
On simplifying, we get
Squaring both sides
Subtract b from both sides
On simplifying, we get
Squaring both sides
Now, we substitute this value in the original equation
Hence, b = 81 is an extraneous solution.
Therefore, the given equation has no solution.
