10 people because all the sisters have the same brother so 7+1+2.
Answer: 14x^7
You add the coefficients (numbers to the left of the variable terms) to get 6+8 = 14 which is the coefficient of the final answer. The x^7 stays the same. It's like saying "we have 6 apples added to 8 apples, so there are 14 apples overall". Replace "apples" with "x^7" and it's the same idea.
Answer:
37/8 (fraction) or 4.625 (decimal) or 4 5/8 (mixed number)
Step-by-step explanation:
L = 5 and w = 3
Perimeter = 2(l + w)
P = 2(5 + 3)
P = 2(8)
P = 16 cm
Area = l*w
Area = 5*3
Area = 15 cm^2
2 miles is bigger because 3 kilometers is 1.86 miles when converted to miles.
