10 maybe I’m not sure but if this is a question from your teacher then ask them what the f&&&&
<span>(a+7) * (a-4)
a^2 - 4a + 7a - 28
a^2 + 3a - 28</span>
R = -2 :) hope this helps
It is 5 becuase 5 times 1 is 5
The product of the whole integers is 24, hence Tammy’s estimate is right, but the<u> actual product should be 24.78.</u>
<h3>Product of decimals</h3>
The decimal numbers are written with the decimal point included. For instance 2.3 is pronounced as 2 point 3.
Given the product of the decimals
4.2 * 5.9
The following calculation was made by Tammy
<em>Estimated product: 4.2 (5.9) almost-equals 4 (6) almost-equals 24. Exact product: 4.2 (5.9) = 2.478.</em>
4.2 is approximately equal to 4
5.9 is approximately equal to 6
Take the product of the whole number
Product = 4 * 6 = 24
Since the product of the whole integers is 24, hence Tammy’s estimate is right, but the<u> actual product should be 24.78.</u>
