Answer:
Addition should be performed last, because of PEMDAS.
Step-by-step explanation:
in pemdas multiply/divide comes before add/subtract so therefore you would multiply 7 x 4 first, even though addition comes before it in the problem.
Answer:
About 4 should be below
Step-by-step explanation:
Ok so 2(x+1) would be two times the sum of a number and one. “Sum of a number and one” is just “x+1” and then it’s two times that because the two is outside of the parentheses.
And then 2x+1 would be the product of two and a number increased by 1. The product is two and a number is 2x and then increased by 1 is the +1
The answerssssssssssssss is 90.
