Answer:
The equivalent expression is c
Step-by-step explanation:
You need to factorise 4(2x-6)
So multiply 4 by the numbers in the brackets:
4*2x=8x
4*-6=-24
And the answer is 8x-24
Answer:
x=20
Step-by-step explanation:
x-19=1
x=1+19
x=20
Answer:

Step-by-step explanation:



Raising e to both sides cancels out the natural logarithm on the left side and we have our exponential form. This works with other bases (recall that the natural logarithm, ln, has base e)
Answer: see attachment below
Step-by-step explanation:
Answer:
The shortest side is 20 feet, the second side is 24 feet and the third side is 36 feet.
Step-by-step explanation:
Assuming that the shortest side of this triangle has a length of "x" feet, then one side is "x + 4" feet and the third is "2*x - 4" feet. Since the perimeter of the deck is 80 feet, then the sum of the length of these sides should be equal to that.

The shortest side is 20 feet, the second side is 24 feet and the third side is 36 feet.
