Answer:
12a^2 - 9a + 5
Step-by-step explanation:
(5a^2 - 6a - 4) - (-7a^2 + 3a - 9)
5a^2 + 7a^2 = 12a^2
-6a - 3a = -9a
-4 + 9 = 5
12a^2 - 9a + 5
Answer: 4x² + 5x + 3
<u>Step-by-step explanation:</u>

T(110) is used to calculate the value of T when w = 110.
<h3>
Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change (slope) and b is the y intercept.
Given the linear equation:
T(w) = 530 - w
Hence T(110) is used to calculate the value of T when w = 110.

Answer:
Yes, 2 yards is greater than 5 feet. 1 yard is equal to 3 feet, so 2 yards is equal to 6 feet. 6 feet is more than 5 feet.
Answer:
y= -2x-1
