Answer:
10
Step-by-step explanation:
Follow PEMDAS
5 (2+1) x 2 divided by 3
calculate within parenthesis
(2+1) : 3
5 x 3 x 2 divided by 3
multiply and divide (left to right)
= 10
* x = times sign
<span>We have to use PEMDAS for this expression.
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
</span>(2x^2 - 5x + 4) Original Mathematical Expression
[2(7)^2 - 5(7) + 4] Plugging the value of x, 7 into expression.
There are parentheses, so that means we have to work in them.
There are exponents, so we have to do those first.
[2(49) - 5(7) +4] Exponents.
There is multiplication, that we can do, so we do that left to right.
[98 - 35 + 4] Multiplication.
There is no division.
There is addition and subtraction, so we do those left to right.
[63 + 4] Subtraction.
67 Addition.
Final Answer: 67
It seemed like it should have been so simple. There was nothing inherently difficult with getting the project done. It was simple and straightforward enough that even a child should have been able to complete it on time, but that wasn't the case. The deadline had arrived and the project remained unfinished.
Answer:
v=9
Step-by-step explanation:
