Question

Answer 1

Answer:

x=1 is ur answer plz mark me as a brainlist

Answer 2

Answer:

On expansion the result we get is $x^2-x-72$

Step-by-step explanation:

(x+8)(x-9)=$x^2-9x+8x-72$

=$x^2-x-72$

This product is simply multiplication.

Let's understand multiplication:

Multiplication is an operation that represents the basic idea of ​​repeatedly adding the same number. The numbers that are multiplied are called factors, and the result obtained after multiplying two or more numbers is called the product of those numbers. Multiplication is used to simplify the task of repeatedly adding the same number.

Example: If there are 6 boxes of cupcakes and each box has 9 cupcakes, find the total number of cupcakes.

Solution: We can solve this question by addition, but adding them would take longer to get the answer. So 9 + 9 + 9 + 9 + 9 + 9 = 54 cups. In other words, when we have larger numbers at our disposal, then multiplication is useful.

Now we will use multiplication to solve this problem. Multiply the number of boxes by the number of baskets in each box. If we multiply by 6 x 9, we get the total number of cupcakes, which is 6 x 9 = 54 cupcakes. So we can see that we can achieve the same result in less time. This is why multiplication is also called repeated addition.
