Answer:
19/3 or 6.33 continuing
Step-by-step explanation:
using pemdas, do the exponent first
6-2=4
then multiply by 4
4x4 is 16
add 3^2 to this, which = 9
so 16+9-6 is on top which equals 19, this is over 3
so 19/3
Answer:
114 feet
Step-by-step explanation:
the black and white will both have the same area. and given that each path is 1 ft wide and initially 12 ft long we can slowly determine the area.
x times 1 will still equal x
12(1) still equals 12 so we can just write it as 12.
12+12+11+11+10+10+9+9+8+8+7+7= 114
where I came up with this? there are a total of 12 sides if you follow the black path. and by every 2 sides the path gets shorter by 1 foot.
the white side also has 12 sides if you look. therefore both the black and the white part of the shape will have an area of 114.
Among many other formulas, the area of a triangle is
where B is the angle between sides a and c.

Bonus. Here's a formula for the area S of a triangle your teacher doesn't know:
Answer:
your answer is 10/3 (fraction)
Step-by-step explanation:
120-40=80
4 x 6=24
80/24=
- first divide both sides by four and get 20/6
- then divide by 2 to get 10/3 (fraction form)
