Sure. The height of the tree is a function of the time in days. Let's call the function h(t) where t is the time in days.
At t=0 we know h(t)=5 centimeters and each day we increase 2.5 centimeters. So our function is
We want to find t when h(t) = 65 so our equation is
That's the answer for the first box. We solve for t:
The expression means that you have to cube the value of and multiply it by the value of .
So, the value of is 5, which becomes 125 when cubed. When we multiply it by the value of , which is 10, the result is 1250:
Answer:
number: 1,3,5
Step-by-step explanation:
Your answer is 4a+2.
5(2a+4)+a-7a-18
10a+20+a-7a-18
10+a-7a+20-18
11a-7a+2
4a+2
(3,5)
