Answer:
Your answer will be D. He knows that 30 × 16 is 5 then multiples 5 by 5 to get 25.
Assume that the notation (a,r,s,t) means multiply q and r, then add the product to s and (2,6,4,8)+(4,7,2,6)? Please show work a

Answer: 7.0 (choice E)</h3>
=============================================
Work Shown:

Let m = 2 so we can use this result later.

Let n = 5 so we can use this result later.
Add the two results.
m+n = 2 + 5 = 7.0 is the final answer.
Answer:
6in
Step-by-step explanation:
Using the pythagerous thereom,
10^2 = 8^2 + b^2
b^2 = 10^2-8^2
b^2 = 100-64
b^2 = 36
b = 6

<h2>a) 16y</h2><h2>b) 8y</h2>
a) First, multiply the numbers 8 and 2, and we get 16.
Now, we have to multiply 16 and the algebraic notation “y”, we get the result of 16y.
<h3><u>
Whenever you multiply the number(s) with algebraic notations, you need to multiply the number(s) and write the algebraic notation at the end.</u></h3>
<u></u>
b) Multiply the number 8 and the algebraic notation “y”, and we get the result 8y.
