Answer:
I'm assuming the 2 after 9t and -2t means squared.
7t² + 12t + 4
Step-by-step explanation:
To simplify the expression we should combine like terms. Like terms are terms with same variables and powers.
Let's start with 9t² and -2t² since they have the same variable and power of t². To combine them we should add them together which would be: 9t² + (-2t²) = 9t² - 2t² = 7t²
Next we can combine 7t and 5t since they have the same variable and power of t. 7t + 5t = 12t
4 doesn't have any like terms so we leave it as it is.
Lastly we add all of our terms: 7t² + 12t + 4
It should be 3cm if I did it right
Answer:
4y-12
Step-by-step explanation:
To multiply a sum (or difference) by a factor, each summand (or minuend and subtrahend) is multiplied by this factor and the resulting products are added (or subtracted).
If the operation outside the parentheses (in this case, the multiplication) is commutative, then left-distributivity implies right-distributivity and vice versa, and one talks simply of distributivity.
The correct answer is A: a steel building.
Explanation:
A steel building will have the lowest premiums out of all the choices given above. After reading several insurance companies policies, a steel building has premiums 30% lower than any other homeowner policy. Steel is harder to destroy in a fire and the damage would be less than a wood home, mixed composition, or even an all brick home.
A wood home has the highest premiums out of all the choices given. When one catches on fire, they will burn fast and usually is a total loss unless the fire trucks get there in minutes.
A brick home can still be destroyed by fire on the inside even if the damage is minimal on the outside of the home.
A mixed composition home, will also be damaged by fire and could be a total loss unless fire trucks are there within minutes.
