The first one is 0 and the second one is 3
18a+(a−9)2
Distribute:
=18a+a2+−18a+81
Combine Like Terms:
=18a+a2+−18a+81
=(a2)+(18a+−18a)+(81)
=a2+81
Answer:
=a2+81

The range of the function c = 50t + 200 is given by [200, ∞).
<h3>What is a
linear equation?</h3>
A linear equation is in the form:
y = mx + b
Where y, x are variables, m is the rate of change and b is the y intercept.
Let c represent the distance travelled in t hours, hence:
c = 50t + 200
The range of the function c = 50t + 200 is given by [200, ∞).

Answer:
60 small and 140 large = 60 + 280 = 340 this is correct!
Step-by-step explanation:
I guess we just use the process of eleimation.
50 small and 150 Large = 50+300 = 350 so that's not right.
130 small and 70 large = 130 + 140 = 270 so, that's not right.
120 small and 80 large = 120 + 160 = 280 so, that's not right.
60 small and 140 large = 60 + 280 = 340 this is correct!
