It changes it into negative
We just need to get the perimeter of the backyard.
Whole rectangle: length = 7ft ; width = 5 ft
Perimeter = 2(7+5) = 2(12) = 24 ft
8.5, since there are 2 significant digits, the only 2 numbers would be 8 and 4, so round at 4 since 5 isn't included by is above and equal to 5
Answer:
the first one
4*10^12
Step-by-step explanation:
I'm assuming we're solving for x.
One property of a straight line is that the angles that make a straight line have to add up to 180 degrees.
Given this information, we know that 4x + 5 + 41 = 180
4x + 46 = 180
4x = 134
x = 134/4 = 33.5
