The expression for the perimeter would be
2(x) + 2(2x+7)
which can be simplified to 2x+4x+14
which equals 6x+14
Answer:
-3
Step-by-step explanation:
complete operations and rearrange to y = mx + b format
y + 1 = -3(x-5)
y + 1 = -3x + 15
y = -3x + 14
slope is -3
Obtuse angle................................
Answer:

Step-by-step explanation:
An irrational number is a number that isn't a whole number (integer).
= 7.07
= 1
= 5
= 3
The first one is the only one that isn't an integer. So it is the answer.
area of perimeter : length × height
= 10.8km × 6km
=64.8km^2
