Callum must buy one packet of dog food every 10 days
Answer and Step-by-step explanation:
First, you create an expression that equals the perimeter of the shape.
5r + 2s + 3r + 2s + 5r + 2s + 3r + 2s
<u>Simplify</u>
16r + 8s
Now we look at the students' expressions.
I can see that Brain's expression is equivalent to perimeter of the shape. Do you know why?
It is because his answer is the un-distributive version of our answer.
He simply took out the common number that is in 16 and 8, which 8.
<u>So, Brian is correct.</u>

<span>An arithmetic or geometric is a recursive sequence, because you can write it in terms of the previous term adding or multiplying some constant respectively. A recursive sequence however, is not always arithmetic or geometric.</span>
Answer:
V = 60 m3
Step-by-step explanation:
Volume of a square pyramid:
V = (1/3)a2h
Slant Height of a square pyramid:
By the pythagorean theorem we know that
s2 = r2 + h2
since r = a/2
s2 = (1/4)a2 + h2, and
s = √(h2 + (1/4)a2)
This is also the height of a triangle side
Answer:
one solution
Step-by-step explanation:
4x + 13 = 3x + 15
subtract 3x from both sides:
x + 13 = 15
subtract 13 from both sides:
x = 2
one solution
