Hi there!
If you wanted to show your work, a good idea would be showing what numbers you would approximate or round the two numbers to, and divide the numbers.
Hope this helps!
Degree is 3 and total of two terms.
Answer: D
if correct pls give me a heart and mark brainleist as a thank you!
It is just doubled the number before so the next number would be 160, then it would be 360, 720, etc..
Using it's concept, it is found that the coefficient of the mathematical expression 7m² + 2(19) is of 7.
<h3>What is the leading coefficient of a polynomial?</h3>
The leading coefficient of a polynomial is the <u>term that multiplies the highest exponent</u>.
In this problem, the expression is given by:
7m² + 19.
The highest exponent is of 2, in m², hence the leading coefficient is of 7.
