Question

Multiply the following
1)x+9y by 4_y
2)6-7z by p+z ​

Answer 1

Step-by-step explanation:

Nonrenewable energy resources, like coal, nuclear, oil, and natural gas, are available in limited supplies. This is usually due to the long time it takes for them to be replenished. Renewable resources are replenished naturally and over relatively short periods of time.

Answer 2

Step-by-step explanation:

Question :-

Multiply the Following :- (3x - 5z) by (2y - 4z)

Solution :-

By using the Distributive Law of Multiplication over Subtraction twice, we get their Product as -

\begin{gathered}\begin {aligned} \bold {(3x - 5z)(2y - 4z)} & = 3x \times (2y - 4z) + (-5z)\times (2y - 4z)\\\\& \Rightarrow 6xy - 12xz + (-10yz) + 20z^2\\\\& = \bold {6xy - 12xz - 10yz + 20z^2} \end {aligned}\end{gathered}

(3x−5z)(2y−4z)

=3x×(2y−4z)+(−5z)×(2y−4z)

⇒6xy−12xz+(−10yz)+20z

2

=6xy−12xz−10yz+20z

This Method is also known as the Horizontal Method.
