Answer:
21
Step-by-step explanation:
dog = 35/85 = x/51
=> x = 35 x 51 / 85 = 7 x 51 / 17 = 21
Answer) $23
Explanation)
10 x 2.29 = 18.9
1.89 + 1.89 = 3.78
18.9 + 3.78 = 22.68
Your answer is 1. Hoped this has helped
A) x2 + 8x + 16
= x2 + 4x + 4x + 16
= x(x+4) + 4(x+4)
= (x+4)(x+4) these are the equations of the two sides - they are the same because it is square. So the equation of one side is 1x + 4
b) The perimeter is the sides all added together, so that is
x+4+x+4+x+4+x+4 = x+x+x+x+4+4+4+4
= 4x+16 or 4(x+4)
c) When x=8 then the the perimeter is 4 lots of 8+4 inches which is 1 foot. 4 lots of 1 is 4, so the perimeter is 4 feet.
2) The difference of two squares can be written in the form x2 - y2. This can be written as (5n)2 -20, but because 20 is not a square number it can't be written as something-squared.
96 divided by 16 is 6 so you would need exactly 6 bags to store the 96 dog treats
