Answer:
21.6, 5.4
Step-by-step explanation:
a=4b
a+b-2=25
5b-2=25
5b=27
b=27/5
a=4*27/5
Answer:
Step-by-step explanation:Let a be the length of line
from question we know that
a+3 is another line
Here
a+(a+3)=15. ( Given in question )
2a = 15 -3
2a=12
a=12/2
a=6
Here a and a +3 are the length of the line
Finally ,6 and 9 are the lengths
We have been given the function

We have to find the value of f(3). In order to find the same, substitute x=3 in the given function.

Now, we simplify this step by step.
First of all
. Thus, we have

Now, we can easily simplify it by PEMDAS


Therefore, the value of f(3) is 98.
3+1=4.
8x0.5=5.
4x1=4
25-21=4
