First one (20 characters) hope this helped
Follow the order of operation: PEMDAS
Parenthesis
Exponents (and roots)
Multiply
Divide
Add
Subtract
3 x (7-2) + 4
first do Parenthesis (as it shows up first)
7 - 2 = 5
Next, Multiply (the next one you have to do)
5 x 3 = 15
Finally, add
15 + 4 = 19
B. 19 is your answer
hope this helps
Answer:
To create the sketch of a polynomial function there are key features are necessary and these are the vertex, axis of symetry, x and y intercepts
Step-by-step explanation:
To create the sketch of a polynomial function there are key features are necessary and these are the vertex, axis of symetry, x and y intercepts
One of the key features arte the vertex and this shows where it changes concativity.
While the x and y intercepts give you a couple of points of reference.
Also, the axis of symetry is only applicable to even degree polynomials
Answer:
I believe the answer is 4.943 :)

<h3>What is an expression?</h3>
Expression is a finite combination of symbols that is well-formed according to rules that depend on the context. An expression is a combination of numbers, variables, or a combination of numbers and variables, and symbols and it is connected by the sign of equal.
We have,
Expression -8(2a - 1) = 36
So,
Now,
To get the solution to this expression,
i.e.
-8(2a - 1) = 36
Rewrite it as,
i.e.
Opening Brackets,
We get,
-16a + 8 = 36
Now,
Taking variable terms on one side and other terms on another side,
We get,
-16a = 36 - 8
On solving we get,
-16a = 28
i.e.
a = 
So,
The solution to the given equation is .
Hence, we can say that the solution to the given equation is .
