Answer:
i) or
- union, U
- addition, +
ii) and
- intersection, (upside down U)
- multiplication, x
So first multiply the whole numbers.
6x2=12
Now multiply 6 and 7. When multiplying a fraction like this, do the numerator ONLY. So it ends up being 42/10. That can be turned to a mixed number. To do that, find out how many times 10 can go into 42. The highest whole number is 4.
10x4=40 and there's 2 left over. So make it 2/10 which can be simplified to 1/5
Now add.
12+4=16+1/5= 16 1/5
C, 40 feet. (14x2)+(6x2)=28+12=40.
Answer:
W = field width = 48 ft
Step-by-step explanation:
Review: the formula for Perimeter of a rectangle is P = 2W + 2L.
Here we're told that the Perimeter is 168 ft. Therefore:
168 ft = 2L + 2W. But we are also told that W = 36 ft. Then:
168 ft = 2L + 2(36 ft) = 2L + 72 ft.
Subtracting 72 ft from both sides, we get 2L = 96, which tells us that:
L = 48 ft.
The field is 48 ft long.
