Answer:
2x² + 12x + 10
Step-by-step explanation:
Area of a rectangle = width x length
Therefore,
Area = (x + 1)(2x + 10)
Expand the brackets: 2x² + 10x + 2x + 10
Combine like terms: 2x² + 12x + 10
A quadratic expression is an expression with the variable with the highest power of 2
The answer is A...
(5 , -4) ...
if you need the steps let me know
Since the equation is a true one, then it is an identity.
<h3>How to illustrate the information?</h3>
It should be noted that the information given is represented as 9(a−4)+3(2a+5)=7(3a−4)−6a+7.
After using the distributive law, the value that will be gotten will be:
15a - 21 = 15a - 21.
Therefore since the equation is a true one, then it is an identity.
