Answer:
60x
Step-by-step explanation: this would be applying the distributive property
40x+30x-10x
70x-10x
hoped this helped
Answer:
I would say triangle. But I am not completely sure!
Step-by-step explanation:
Hope this helps!
According to the rules of indices:
1/a^b=a^-b
thus using this rule, our value will be expressed as follows:
1/z^9=z^-9
Hence the answer is: z^-9
A regular triangle is a triangle with 3 equal sides. A perimeter of a triangle with 3 sides = 3 x length = 3 (length). Since you know that the perimeter is also equal to 18x + 27, therefore,
3 (length) = 18 x + 27
length = (18x + 27) / 3 <-- divided both sides by 3
length = 6x + 9
An expression for the length of one of its sides is 6x + 9.
