Formula for triangle perimeter is: a + b + c. In this scenario we have:
a = 3 feet 8 inches
b = 2 feet 10 inches
c = 4 feet
a + b + c =
= 3 ft + 8 in + 2 ft + 10 in + 4 ft =
= 9 ft + 18 in
We know that 1 foot is 12 inches, so we can simplify the result to this form:
10 ft + 6 in
or:
<u>10.5 feet</u>
line up your decimals and then multiply like usual, next count how many places after the decimal your problem(s) was and place it to your answer

Answer:
-3
Step-by-step explanation:
Use slope formula to find the slope of the first road:
(y2 - y1) / (x2 - x1)
(1 - 5) / (-1 - 11)
-4 / -12
1 / 3
The slope of a line perpendicular to this line would just be the negative reciprocal of the slope:
-3 / 1 or just -3
Step-by-step explanation:
p⁴+8p²q²+16q⁴
(p²)²+2×p²×4q²+(4q²)²
We know that,
Therefore,
- (p²)²+2×p²×4q²+(4q²)²
- (p²+4q²)²
- (p²+4q²)(p²+4q²)
