The value of a will be equal to
for the given expression.
<h3>What is simplification?</h3>
The process of reducing the complex mathematical expressions into the simplest form is called as the simplification.
here we have two expressions.

We can write the expression as:

Hence the value of a will be equal to
for the given expression.

Answer:
75
Step-by-step explanation:
6(10)+15
60+15
I'm not just going to give you that answer, i'm going to teach you how to do it for yourself. this is a function. what you do first is look at what the question is asking you, it's asking you to solve the function, when the value of x are as follows: -2, 1, 2. start with the easiest number, 1, and plug it in for x in each equation.
5• (1)^2 + 0
10• (1)^2 + 0
then set each equation equal to zero
5 • (1)^2 + 0 = 0
10 • (1)^2 + 0 = 0
now solve each equation. make sure the value value you get for the first equation is a negative number, because the question demands that by giving you "x<1"
complete the same steps for each other value to get the answers. hope this helps.
Tell me, what are you doing?
Área, perimeter? Basically what kind of operation is it asking for?!
Divide 30 by 10. 30mph/10seconds = 3mph/seconds
Hope dis helped :)
