Hello I have to right 24 characters but I need some more questions lol but 24
Answer:
The answer is for this question is False
<span>f(x)=<span>x2</span>−1</span>That means to find the value of the function at any value of x, we square x and subtract 1. If <span>x=2a</span>, we square <span>2a</span> and subtract 1:<span>f(2a)=(2a<span>)2</span>−1=4<span>a2</span>−1</span>Now, we know that <span>f(2a)=35</span>so we can find the value of a:<span>f(2a)=(2a<span>)2</span>−1=4<span>a2</span>−1=35</span><span>4<span>a2</span>−1+1=35+1</span><span>4<span>a2</span>=36</span><span><span>a2</span>=9</span><span><span>a=±3</span></span>

Also, I think that Brainly is an awesome app, but there's an app which is doing great work for me in maths, named Gauthmath. I will suggest it. Video concepts and answers from real tutors.
Answer:
$3.91
Step-by-step explanation:
This is a fraction equal to
100 count ÷ 25.54 cost
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 25.54
100 count ÷ 25.54
25.54 cost ÷ 25.54
=
3.915427 count
1 cost
=
3.915427 count
cost
= 3.915427 count per cost
