Answer:
a^2-b^2=(a+b)(a-b) where a=4x and b=5. (4x+5)(4x-5)
Step-by-step explanation:
Since both terms are perfect squares,factor using the difference of squares formula
Answer:
I hoped this helped!
Step-by-step explanation:
First method:
What we can do first is to distribute directly 4.2 to 6 and
0.43, that is:
4.2 (6 + 0.43)
= 4.2 * 6 + 4.2 * 0.43
= 25.2 + 1.806
= 27.006
Second method:
We can add the two numbers 6 and 0.43 then multiply with
4.2, that is:
4.2 (6 + 0.43)
= 4.2 (6.43)
= 27.006
What we see is the Distributive Property of multiplication
which states that multiplying the sum of a number is similar to multiplying
each number and then adding the products.
